A distribution centre is one of the most capital-intensive and operationally consequential investments a supply chain organisation makes. Get the design right and you have a facility that runs efficiently for 10–15 years, absorbs volume growth without constant disruption, and gives the operation genuine competitive advantage. Get it wrong — and wrong usually means locked-in at the briefing phase, before anyone has started drawing — and you spend the life of the lease working around structural constraints that cost you money every single day.

This article is a practical guide to the DC design process: how to define the brief, how to size the facility, how to make the layout decisions that determine operational performance, how to select the right storage and materials handling systems, and how to manage the design project to avoid the mistakes that consistently derail Australian DC projects.

It is written for supply chain leaders, operations directors, CFOs, and project teams who are facing a new DC build or fit-out decision and want to understand what good looks like — and where the traps are.

Why DC Design Gets Expensive When It Goes Wrong

The consequences of a poorly designed distribution centre are not immediately visible. They accumulate. A receiving dock that is two positions short of what the throughput requires forces operations to manage daily inbound queues. A pick face that was sized for current SKU counts and cannot expand without a racking reconfiguration becomes a constraint within three years of opening. A floor-level mezzanine installed to accommodate manual picking that is later incompatible with the goods-to-person automation the business wants to deploy creates a retrofit problem at seven figures.

None of these are technology failures. They are design failures — specifically, failures to adequately define requirements before the design work began. The brief drives everything. A weak brief produces a facility designed to the wrong parameters, and the cost of correcting that inside a 10-year lease is enormous.

The starting point for any DC design project is therefore not AutoCAD. It is a rigorous requirements definition process that establishes what the facility needs to do — not just today, but across the full lease horizon.

Stage 1: Defining the Brief — The Most Important Document You Will Produce

The design brief is the document that defines what the distribution centre must achieve. Every subsequent design decision — size, layout, storage systems, automation, dock configuration — is derived from the brief. Errors in the brief produce errors in the design that cannot be corrected without starting again.

A complete DC design brief covers the following dimensions:

Throughput requirements. What volumes does the facility need to handle — inbound receipts, outbound despatches, and the peak-to-average ratio that determines how the facility must be sized. Many Australian DCs are designed to average throughput and then struggle operationally during the peaks (promotional periods, seasonal demand, end-of-month retailer orders) that actually determine how the facility needs to function. Size for the operational peak, not the annual average.

Order profile. What does the outbound order look like — pallet orders, carton orders, unit picks, or a mix? The order profile is the single most important determinant of picking system design. A DC despatching 95% full pallet orders needs a completely different pick design from one despatching mixed-carton store replenishment or e-commerce unit picks. Getting this wrong — designing a pick operation for the wrong unit of measure — is one of the most common and costly DC design errors.

SKU profile. How many active SKUs does the facility hold? What is the velocity distribution — what proportion of SKUs are fast-moving (A-class), medium-moving (B-class), and slow-moving (C-class)? What are the physical characteristics — weight, dimensions, fragility, temperature requirements, hazardous materials classification? The SKU profile determines storage system selection, slotting strategy, and the pick face configuration.

Inventory holding requirement. How many days of stock does the facility need to hold? This determines the storage volume requirement — and therefore a significant component of the floor area calculation. Inventory holding requirements are frequently underestimated in DC briefs because the analysis is done at average inventory levels rather than at the maximum holding position the facility must accommodate.

Growth assumption. The facility will serve the business for the duration of the lease — typically 10–15 years for a purpose-built DC. The brief must include a credible view of volume growth over that period, with the design incorporating sufficient flexibility to accommodate that growth without a major reconfiguration. A facility designed for today's throughput with no expansion provision will be operationally constrained within three to five years.

Operating model. How will the facility be staffed and operated? What shift patterns? What degree of automation is being considered — now or in the future? Will the facility operate under a WMS, and if so, which one? The operating model directly affects the physical design: automation infrastructure requirements, power and data provisions, floor flatness specifications, and the spatial requirements for operational support areas.

Special requirements. Temperature-controlled storage (chilled, frozen, ambient-controlled), hazardous materials storage and handling, pharmaceutical serialisation and traceability requirements, bonded storage, returns processing areas, value-added services (pick-and-pack, kitting, labelling). Each of these has specific physical design implications that need to be captured in the brief before the design begins.

Stage 2: Sizing the Facility

With the brief defined, the facility can be sized. DC sizing is an engineering calculation, not an estimate — and the quality of the output depends entirely on the quality of the input data.

The sizing process works through three components:

Storage volume calculation. Convert the inventory holding requirement (in units or pallets) into a physical storage volume, accounting for the storage systems being used. Selective racking at 9–10 metres clear height yields a fundamentally different storage density from drive-in racking, narrow-aisle racking, or automated storage. The storage volume calculation also needs to account for the space occupied by aisles, which varies significantly by storage system — selective racking with standard forklifts requires aisle widths of 3.0–3.5 metres; very narrow aisle (VNA) racking with man-up trucks reduces this to 1.6–1.8 metres, increasing storage density by 30–40% at higher capital and operating cost.

Operational area calculation. The non-storage operational areas of the DC — inbound staging and receiving, outbound marshalling and despatch, pick faces, packing benches, value-added services, battery charging, maintenance, waste management, and staff amenities — typically represent 25–35% of total floor area in a well-designed facility. These areas are frequently undersized in initial design briefs because the focus is on storage, and the operational consequences of inadequate staging and marshalling space are only felt once the facility is running.

Dock calculation. The number of inbound and outbound dock doors required is determined by the peak hourly throughput of vehicles, the average turnaround time per dock, and the separation required between inbound and outbound operations. Dock underprovision is a structural constraint that cannot be easily remedied within an existing building — the number of dock positions should be calculated for the peak operational position over the lease horizon, not current average throughput.

The output is a total net internal area (NIA) requirement. To convert this to a gross internal area (GIA) or gross external area, add a structural factor (typically 3–8% for columns, walls, and plant rooms) and confirm against the clear internal height assumption.

In the current Australian industrial property market, where national vacancy rates edged upward through 2024 and into 2025 as new supply entered the market Trace consultants, there is more tenant negotiating leverage than has existed for several years — but lease economics still favour locking in a well-sized facility over signing a lease and then discovering the building is inadequate.

Stage 3: Layout Design — The Four Principles

With the size established, the internal layout can be designed. Four principles govern distribution centre layout, and the best DC designs achieve a well-balanced optimisation across all four simultaneously. Optimising for one at the expense of the others is a common design error.

Flow. Goods should move through the facility in a logical, unidirectional sequence — inbound, storage, pick, pack, despatch — with minimal backtracking and no cross-flow between inbound and outbound traffic streams. The three canonical layout configurations are the I-shape (receive at one end, despatch at the other — maximum separation, maximum hardstand requirement), the U-shape (receive and despatch on the same elevation — most common in Australian conditions, minimises hardstand), and the L-shape (receive and despatch on perpendicular elevations — suits irregular sites). The right choice depends on site geometry, relative volumes of inbound and outbound activity, and the separation requirements of the specific operation.

Accessibility. Every storage location needs to be accessible to the handling equipment used to service it, at the frequency required by the product's velocity. Fast-moving SKUs need pick faces that are immediately accessible, at the right height, without retrieval from depth storage. Slow-moving SKUs can be stored at height or in deep locations where access takes longer. Designing storage accessibility around velocity — putting fast movers closest to the pick despatch point, in the most accessible locations — is the slotting principle that has the greatest impact on pick productivity.

Space utilisation. The cubic volume of the building should be used as efficiently as the handling equipment and storage systems allow. Australian industrial property is expensive; unused cubic volume is wasted capital. The tension is between space utilisation and accessibility — very dense storage systems (drive-in racking, mobile racking, AS/RS) maximise cubic use but constrain access, while wide-aisle selective racking maximises accessibility at the cost of storage density. The right balance depends on the velocity profile: facilities with a high proportion of slow-moving, low-access-frequency SKUs can justify denser storage systems; facilities with high throughput and frequent access requirements need more accessible configurations.

Safety and throughput. The layout must provide clear separation between forklift and pedestrian traffic, adequate sight lines at intersections, sufficient aisle widths for the equipment in use, and compliance with Work Health and Safety legislation and the relevant Australian Standards. Safe design is not a constraint imposed on operational design — it is an integral part of it. Facilities that compromise safety in the pursuit of storage density or throughput create liability and operational disruption that far outweighs any efficiency gain.

Stage 4: Storage System Selection

Storage system selection is one of the most consequential technical decisions in DC design. The wrong system — one that is right for the product range in the brief but wrong for how the range evolves — becomes a stranded asset.

The main storage system options and their appropriate applications:

Selective pallet racking is the most common system in Australian DCs — every pallet position is directly accessible, the system is highly flexible (beam heights can be adjusted, configurations changed), and it suits wide velocity ranges. It is the right default choice for most general merchandise, FMCG, and retail distribution applications. Its limitation is space efficiency: because every pallet position requires its own aisle access, utilisation of the building footprint is lower than denser systems.

Drive-in and drive-through racking sacrifices individual pallet accessibility for density — forklifts drive into the racking structure to place and retrieve pallets in depth. It is appropriate for high-volume, low-SKU-count operations with limited product variability and where FIFO discipline is either not required or can be managed structurally (drive-through for FIFO, drive-in for LIFO). Common in cold storage (where maximising refrigerated volume is paramount) and beverage distribution.

Narrow-aisle and very narrow aisle (VNA) racking reduces aisle widths from the 3.0–3.5 metres required by counterbalance forklifts to 1.6–1.8 metres by using guided turret trucks or man-up order pickers. The density improvement is substantial — 30–40% more pallet positions on the same footprint — at the cost of specialist equipment, higher capital investment, and reduced operational flexibility. It suits operations where land cost is high and the investment in specialist equipment is justified by the density improvement.

Automated Storage and Retrieval Systems (AS/RS) — including stacker cranes, shuttle systems, and goods-to-person systems — deliver the highest storage density and can operate at heights of 30–40 metres. They are increasingly relevant for Australian operations as labour costs rise and automation technology costs fall, but they require significant capital investment, have specific building specification requirements (floor flatness, seismic considerations, sprinkler system design), and are most appropriate for operations with the throughput to justify the investment. The business case is strongest for operations with high SKU counts, significant slow-moving stock, or strong labour cost pressure.

Mezzanine and multi-level picking suits operations with high unit-pick requirements — e-commerce fulfilment, pharmaceutical distribution, and parts distribution. Mezzanines add effective floor area within the building height, supporting manual or semi-automated pick operations across multiple levels. They require careful structural design and fire engineering, and the decision to install mezzanine structure needs to be made early in the design process, as retrofitting is expensive.

Stage 5: Dock and Yard Design

The dock and yard are frequently the most undersized elements of Australian DC designs — because they are the least visible in a building floorplan but among the most operationally critical.

Dock door quantity should be sized for the peak inbound and outbound vehicle arrival rate, with separate dock zones for inbound and outbound to avoid cross-contamination of receiving and despatch operations. Dock levellers, dock seals, and vehicle restraints are standard equipment in a well-equipped Australian DC — not optional additions.

Yard design needs to accommodate the full length of B-double or road train vehicles where applicable, provide adequate turning radii, separate truck movements from staff car parking, and manage the queue of vehicles waiting for dock allocation during peak periods. Yards that are too small to accommodate the vehicle mix that actually arrives at the facility — a common problem when the brief was written assuming semi-trailers and the customer shifts to B-doubles — create serious operational bottlenecks and safety risks.

Container unloading areas, wash-down bays, waste management areas, and trailer parking for pre-loaded or pre-staged vehicles all need to be designed into the yard from the outset.

The Australian Context: Specific Design Considerations

Several factors make DC design in Australia distinct from the generic principles in international reference material.

Industrial property constraints. The Australian industrial property market is dominated by institutional landlords — GPT, Goodman, Charter Hall, Logos, CEVA — with standard speculative DC products in the 10,000–50,000 sqm range concentrated in established logistics precincts in western Sydney, the Melbourne west (Laverton, Truganina, Dandenong), Brisbane's Trade Coast and southern corridor, and Perth's Kewdale and Hazelmere precincts. Most Australian occupiers take existing buildings rather than building to suit, which means fitting the design to the building rather than designing the building from scratch. This requires a different approach: the brief must be defined first, the building found second, and the fit-out designed to the specific building's structural parameters — clear height, column grid, dock positions, yard depth, and power supply.

Clear height. Australian speculative DC buildings are now typically built to 12–14 metres clear internal height, with some premium logistics facilities at 15–17 metres. This is substantially higher than the 9–10 metre facilities that dominated the market until the mid-2010s, and it opens up storage system options — particularly high-bay racking and AS/RS — that were not practically available to most occupiers previously.

Labour market. Warehouse labour is structurally scarce and expensive in Australian gateway cities. This shifts the automation business case: the threshold throughput at which automated picking systems are financially justified is lower in Australia than in comparable international markets, because the labour cost it displaces is higher. DC designs that do not at minimum provision for future automation — power supply, floor flatness, structural clearances — are foreclosing options that may become economically necessary within the lease term.

Fire engineering and sprinkler design. Australian Standards AS 2118 and the requirements of AFSS (Automatic Fire Suppression Systems) significantly affect racking height and configuration in Australian DCs, particularly for FMCG, plastics, and high-bay applications. Early engagement with fire engineers during the design process — before racking design is finalised — avoids costly late-stage redesign.

How Trace Consultants Can Help

At Trace Consultants, DC design advisory is part of our Warehousing & Distribution practice. We help Australian organisations define their DC requirements, assess building options against those requirements, design the internal layout and storage system configuration, develop the automation business case, and manage the design and fit-out project.

Our approach bridges the gap between property and operations — we understand both the industrial property market and the operational requirements of a well-run distribution centre, and we design facilities that work as operations rather than as impressive buildings. We also integrate Supply Chain Network Design thinking into DC projects, ensuring facility-level decisions are consistent with the network strategy rather than made in isolation.

We work across FMCG and manufacturing, retail, health and aged care, and government and defence. DC design requirements differ significantly across sectors — the design brief for a pharmaceutical cold chain DC is fundamentally different from a general merchandise retail DC — and that sector knowledge shapes every stage of the process.

The Brief Is the Design

Every structural problem in a running distribution centre can be traced back to something that was either missing from the brief or inadequately defined in it. Peak throughput not modelled. Growth not provided for. Order profile assumed rather than analysed. Dock positions sized for today's vehicle mix, not tomorrow's.

The investment in getting the brief right — rigorous data analysis, honest operational forecasting, proper stakeholder engagement — is trivial compared to the cost of operating a constrained facility for a decade. The brief is the design. Everything else is implementation.

How to Select a 3PL in Australia: A Practical Guide for Operations and Supply Chain Leaders

Choosing a third-party logistics provider is one of the most consequential operational decisions an Australian business can make. Get it right and you gain a scalable, cost-efficient distribution capability with a partner who grows with you. Get it wrong and you're locked into a contract that underdelivers on service, erodes customer relationships, and costs more to exit than it would have cost to do it properly the first time.

Most businesses approach 3PL selection the wrong way. They start with a shortlist of providers — often compiled from industry contacts or a quick search — and run a loose tender before picking whoever came in cheapest or made the best impression in the room. What gets skipped is the foundational work: defining what you actually need, specifying it clearly enough that providers can price it accurately, and building a scorecard that evaluates the things that will matter in year two and three, not just at contract signing.

This guide covers how to run a rigorous 3PL selection process in Australia — from the requirements definition phase through to transition and go-live. It applies to businesses outsourcing logistics for the first time, and equally to those retendering an existing arrangement where performance has drifted.

What Is a 3PL and What Does It Actually Do?

A third-party logistics provider manages some or all of the warehousing, inventory management, and distribution functions for a business. In the Australian market, 3PL services typically span: inbound receiving and put-away, bulk and pick-face storage, order picking and packing, outbound despatch and carrier management, returns processing, and inventory reporting.

Beyond that baseline, 3PLs vary considerably in capability. Some offer value-added services — kitting, labelling, quality inspection, cold chain management, dangerous goods handling. Some have sophisticated warehouse management systems (WMS) with real-time visibility and customer portal access. Others are running basic operations that look more impressive in a sales presentation than they do on the warehouse floor.

The distinction that matters most is between providers who are genuinely integrated logistics partners — capable of contributing to your supply chain strategy, managing complexity, and scaling with your business — and providers who are fundamentally space-and-labour businesses offering a commodity service. Both have their place. Knowing which one you need before you go to market is the starting point for a good selection process.

Before You Go to Market: Define Your Requirements

The single most important step in a 3PL selection is the one most businesses skip or undercook: a rigorous definition of current-state requirements and future-state needs before any provider engagement begins.

Volume and throughput profile. How many pallets in and out per week? How many order lines per day? What is your peak-to-average ratio — do you run at three times average volume in the lead-up to Christmas, or is throughput relatively consistent? A 3PL that can handle your average volume may fall over at peak. Understanding and communicating your profile accurately — not optimistically — is essential for getting accurate pricing and capacity commitments.

SKU profile and product characteristics. How many active SKUs do you carry? What are the storage requirements — ambient, temperature-controlled, hazardous, high-value? What does your pick profile look like — high-volume single-SKU orders, or complex multi-line orders with value-added processing? The physical characteristics of your product (dimensions, weight, fragility, shelf life) determine what infrastructure and capability a 3PL needs to service you.

Service level requirements. What do your customers require in terms of order cut-off times, despatch frequency, and delivery windows? Do you ship direct-to-consumer, direct-to-trade, or both? Are there specific carrier requirements from your major customers — some large retailers mandate specific carriers or booking systems? These requirements need to be documented and included in your tender specifications, not discovered after contract signature.

Integration requirements. How does your current order management or ERP system connect to a 3PL's WMS? What data do you need — real-time inventory visibility, despatch confirmations, DIFOT reporting? Integration failure is one of the most common causes of 3PL transition pain. Understanding your technical requirements upfront, and validating that prospective providers can meet them, is non-negotiable.

Growth trajectory. Where will your volume be in two and four years? A 3PL selection should be made for your future business, not your current one. A provider with capacity and capability headroom to grow with you is worth paying a modest premium over one who is the right fit today but will be under pressure in eighteen months.

The Australian Market: What You're Choosing Between

The Australian 3PL market is fragmented. At one end are the large national operators — Linfox, Toll, DHL Supply Chain, Yusen Logistics, CEVA — with multi-site networks, significant technology investment, and the infrastructure to service large, complex accounts across multiple states. At the other end are specialist regional operators who may offer better service levels and more responsive account management for a mid-market business that would be a low priority for a national provider.

Between those extremes is a broad middle market of operators with one or two facilities, varying degrees of technology maturity, and service offerings ranging from basic bulk storage through to sophisticated fulfilment operations. The right choice depends on your requirements — geography, volume, complexity, service level expectations — not on provider size or brand recognition.

A few characteristics of the Australian market worth noting for the selection process. Australia's geography creates genuine logistics complexity — a national distribution network covering Melbourne, Sydney, Brisbane, Perth, and Adelaide requires either a provider with multi-state infrastructure or a deliberate strategy for how secondary markets are served. For businesses whose customers are concentrated in south-east Queensland and the eastern seaboard, a single-site operator may be entirely adequate. For businesses with significant Western Australian volume, the freight cost and lead time implications of eastern-seaboard-only storage are material and need to be worked through explicitly.

Temperature-controlled capability is a genuine differentiator in the Australian market. Cold chain 3PL capacity — particularly for the 2–8°C range — is constrained relative to ambient, and the providers with genuine capability in this space are a smaller subset of the overall market.

Running the Selection Process

A rigorous 3PL selection process runs in four stages.

Stage 1: Requirements definition and longlist development. Build the requirements document — volume profile, SKU profile, service level requirements, integration requirements, growth trajectory. Identify a longlist of eight to twelve providers with plausible capability to meet your needs. The longlist should include both large nationals and credible specialist operators. Don't pre-filter too aggressively at this stage — surprises in both directions are common.

Stage 2: RFI (Request for Information). Issue a structured RFI to the longlist. The purpose is to gather enough information to shortlist to four or five providers for a full tender. Key questions: geographic footprint and capacity, WMS capability and integration track record, relevant customer references (same sector, similar complexity), financial stability, and any specialist capabilities required. Conduct reference checks at this stage — not after you've already chosen a preferred provider.

Stage 3: RFP (Request for Proposal) and site visits. Issue a detailed RFP to your shortlist. The RFP should include your full requirements specification, a standard pricing schedule, and specific questions about how the provider would handle your account. Require providers to submit pricing against your actual volume profile, not a simplified version of it. Visit every shortlisted site before scoring — a warehouse tour tells you more about an operator's culture, systems discipline, and housekeeping standards than any document they produce.

Stage 4: Evaluation, negotiation, and selection. Score proposals against a weighted scorecard that reflects your actual priorities. Price matters, but it is rarely the only thing that matters — and it is often the least reliable indicator of total cost. A provider with higher headline rates and better inventory accuracy, DIFOT performance, and damage rates will typically deliver better total cost than the cheapest quote. Negotiate with your preferred two providers before making a final selection.

What to Put in the Contract

The 3PL contract is where a significant number of Australian businesses underinvest — and where they pay for it later. Key elements that should be explicitly addressed.

Service level agreements with teeth. Define the KPIs — DIFOT, inventory accuracy, order accuracy, inbound turnaround time — with specific targets and specific consequences for missing them. A contract that references service levels but doesn't specify what happens when they're breached is not a contract for performance, it's a contract for goodwill.

Pricing structure and variation mechanisms. Understand exactly how you will be charged — per pallet in, per pallet stored per week, per order line, per carton despatched, per labour hour for value-added services — and how charges vary with volume. Know what happens at peak. Know what the annual CPI or labour cost escalation mechanism is. Pricing surprises are the most common source of 3PL relationship breakdown in the first twelve months.

Technology and reporting obligations. What data will the 3PL provide, in what format, and at what frequency? What portal or API access will you have? What are the response time obligations for data queries or discrepancy investigations? Specify these as contract obligations, not as assumptions.

Exit provisions. How long is the initial term? What are the notice periods? What happens to stock and data on exit — transition assistance obligations, data extraction, final reconciliation? The time to negotiate your exit from a 3PL relationship is before you've entered it, not when things have gone wrong and you're trying to leave.

The Transition: Where 3PL Selections Most Often Fail

Selecting the right provider and then transitioning badly is a more common failure than selecting the wrong provider. 3PL transitions are high-risk operational events — there is a period where stock is moving between sites, system integrations are being tested, and a new team is learning your product, processes, and requirements. Service disruption during this period is almost inevitable unless the transition is planned and managed rigorously.

Key principles for a successful transition: run parallel operations for as long as possible before the cutover; never cut over at peak; test system integration end-to-end before a single live order goes through it; train the 3PL team on your product before go-live, not during; and assign a dedicated transition manager on your side whose job it is to manage nothing else during the cutover period.

The majority of 3PL transition failures are not caused by the provider being incapable — they're caused by insufficient planning, unrealistic timelines, and underestimating the complexity of integrating two organisations' systems, processes, and people.

How Trace Consultants Can Help

At Trace Consultants, we help Australian businesses run rigorous 3PL selection processes — from requirements definition through to contract execution and transition management.

Requirements definition and market assessment. We build the requirements specification that is the foundation of a good selection process — volume and SKU profiling, service level mapping, integration requirements, and growth modelling. We also provide an independent view of the Australian 3PL market, including which providers have genuine capability for your requirements and which are better suited to a different profile.

Procurement process management. We design and run the RFI and RFP process — developing tender documentation, managing provider engagement, facilitating site visits, and building the evaluation scorecard. We ensure you're comparing providers on the dimensions that will determine the quality of the relationship over three to five years, not just the ones that are easy to compare.

Contract negotiation support. We support the commercial negotiation — pricing structure, SLAs, escalation mechanisms, and exit provisions — drawing on benchmarks from comparable Australian 3PL arrangements to ensure you're not paying above market or accepting below-market terms.

Warehousing & Distribution transition management. We manage the transition programme — site readiness, systems integration, stock transfer, parallel running, and go-live — with a dedicated project manager whose job is to get you operational without service disruption.

We work across retail and FMCG, manufacturing, health and aged care, government, and hospitality. The selection methodology is consistent. The right answer for each client is not.

There's a question that sits at the heart of every supply chain, and most organisations don't ask it often enough: is our distribution network actually set up to deliver what we're promising to customers, at a cost we can sustain?

It sounds simple. It's anything but. Network design and warehouse strategy are among the most consequential decisions a business makes — and they're also among the stickiest. Once you've signed a lease, built out a facility, and configured your operations around a particular footprint, you're locked in for years. Get it right and you create a platform for lower costs, faster service, and the flexibility to adapt as conditions change. Get it wrong and you bake inefficiency into the business in ways that are expensive and painful to undo.

In Australia right now, these decisions carry even more weight than usual. The industrial property market is shifting, customer expectations keep ratcheting up, construction costs remain elevated, and the economics of distribution are being reshaped by everything from e-commerce growth to interest rate movements. Organisations that approach network design and warehouse strategy with rigour — grounded in data, not gut feel — will outperform those that don't.

This article lays out how to think about these decisions in the current Australian context, where the common pitfalls are, and how to avoid them.

Why Network Design Matters More Than Most Executives Realise

When people hear "supply chain strategy," they tend to think about procurement contracts, transport rates, or warehouse management systems. Those things matter, but they're all downstream of a more fundamental question: what does the physical network look like?

Network design determines how many distribution centres, warehouses, cross-docks, or fulfilment centres you operate, where they're located, which customers and channels each facility serves, and how inventory is positioned across the network. It shapes your transport costs, your service levels, your working capital, and your ability to respond when things go wrong — whether that's a supplier delay, a demand spike, or a natural disaster.

In Australia and New Zealand, geography amplifies every network decision. The distances between population centres are vast. Freight costs are a significant share of total cost-to-serve. Labour markets vary enormously from one corridor to the next. And port dependencies — particularly for import-heavy businesses — add another layer of complexity that has to be factored into any serious network analysis.

A centralised network with one or two large distribution centres might offer economies of scale in warehousing but push transport costs higher and extend delivery times to regional areas. A decentralised network with multiple smaller facilities brings you closer to customers but increases inventory, complexity, and overhead. The right answer depends entirely on the specifics of your business — your product characteristics, order profiles, service commitments, and growth trajectory.

This is where strategy and network design capability becomes essential. It's not about having a strong opinion on centralised versus decentralised. It's about having the analytical tools and the industry experience to model both options (and everything in between), stress-test them against realistic demand scenarios, and quantify the trade-offs so leadership can make an informed decision.

The Current State of Australia's Industrial Market

Anyone making network decisions in 2026 needs to understand what's happening in the industrial property market, because the window of opportunity is shifting.

Through 2024 and into early 2025, Australia's industrial vacancy rates edged upward as a wave of new supply entered the market. National vacancy averaged around 2.8% through the first half of 2025 and rose to approximately 3.7% by the third quarter — still below the pre-2020 equilibrium of 5%, but enough to give tenants more negotiating leverage than they'd had in years.

That breathing room won't last. Speculative supply is forecast to fall by around 46% over the 2026–2027 period compared to the prior two years. Construction feasibility constraints — driven by elevated build costs and higher required economic rents — are causing developers to delay or shelve projects. At the same time, consumer spending is recovering, leasing activity is strengthening, and gross take-up is projected to reach 3.3 million square metres in 2026 and climb to 3.8 million in 2027.

The result is a market that's heading back towards tighter conditions. National vacancy is expected to peak at just under 4% by mid-2026 before declining to around 2.5% by late 2027. Prime net face rents are forecast to grow at roughly 3.9% per annum through 2026 and 2027, with effective rental growth accelerating as incentives pull back.

For occupiers, the implication is clear: the time to be making network decisions is now, while there's still some choice in the market. Waiting 18 months and hoping conditions will be the same is a gamble that the data doesn't support.

But — and this is the critical point — making a property decision is not the same as making a network decision. Signing a lease because a good deal is available in a particular submarket is not a strategy. It's a reaction. The property decision should follow the network decision, not the other way around. You need to know what network configuration best serves your business before you go looking for buildings.

Where Businesses Get Network Design Wrong

Having worked with organisations across retail, FMCG, government, manufacturing, and services, there are a handful of patterns that come up again and again when network design goes off the rails.

Starting with the building, not the question. This is the most common mistake. A lease comes up for renewal, a property agent presents an opportunity, or the board decides "we need a new DC." The response is to go find a building. But without first understanding the flows, the demand patterns, the cost-to-serve, and the service requirements, you end up with a facility decision disconnected from the network it sits in. The right sequence is always: strategy first, then network modelling, then facility requirements, then property search.

Ignoring the total cost picture. Transport and warehousing costs behave inversely — push one down and the other tends to go up. Organisations that optimise for warehouse cost alone (usually by consolidating into fewer, larger facilities) often find their freight bill blows out. The reverse is also true. A proper network model captures warehousing costs, inbound and outbound transport, inventory carrying costs, and fixed overheads to give a genuine total cost-to-serve view. Without this, you're optimising one line item at the expense of the whole.

Designing for today, not for where you're heading. Networks have long asset lives. Leases are typically 5–10 years, and the capital invested in fit-out, racking, and automation can take even longer to pay back. A network designed purely for today's volumes and channels may be undersized — or oversized — within a few years. Good network design incorporates demand scenarios that account for growth, channel shifts, seasonal variation, and potential disruption. This is where planning and operations capability intersects with network strategy.

Underestimating the labour dimension. Two sites that look identical on a spreadsheet can perform very differently depending on the local labour market. Wage rates, turnover, skills availability, commute patterns, and proximity to competing employers all affect your ability to staff a facility reliably. In Australia, where workforce planning and scheduling is already a challenge for most sectors, this should be a first-order consideration in any location analysis — not an afterthought.

Treating the warehouse as a black box. Network models tend to treat warehouses as cost-per-pallet or cost-per-order nodes. That's fine at a strategic level, but it's not enough when you're making real investment decisions. The internal design of the warehouse — layout, storage media, pick methodology, dock configuration, automation level — directly determines throughput capacity, cost, accuracy, and scalability. Network design and warehouse design need to be done in parallel, not sequentially, because they influence each other in ways that matter.

Warehouse Strategy: More Than Layout and Racking

A warehouse strategy defines what your facilities need to do, how they should be configured to do it, and what investments are required to achieve the desired performance. It sits between your network strategy (which tells you how many facilities, where, and what they serve) and your operational execution (which is the day-to-day running of the site).

For Australian businesses, getting warehouse strategy right is particularly important because of several converging pressures.

E-commerce continues to grow. Online fulfilment demands a fundamentally different warehouse operation than store replenishment. Picking individual items rather than full cases or pallets, managing returns at scale, and meeting next-day or same-day delivery windows all require specific design considerations — from pick-face layout to packing stations to outbound sortation. Many businesses that bolted on e-commerce capability during the pandemic are now discovering that their warehouse operations aren't scaled or designed for the volumes that online represents as a permanent channel. Designing warehouses that can serve both store and online channels efficiently is one of the core challenges for in-store and online retail supply chains.

Labour is scarce and expensive. Australia's warehouse workforce has been under pressure for several years, and the outlook doesn't suggest that's about to change. This makes the case for automation more compelling — but automation is a significant capital investment that needs to be justified against realistic volume projections and operational requirements. The question isn't whether to automate; it's what to automate, when, and to what extent. A phased approach — sometimes called "automation-when-ready" — designs the facility to accommodate future automation while being operationally effective with manual or semi-automated processes in the near term.

Sustainability expectations are rising. Warehouses consume significant energy, particularly when refrigeration is involved. The design of a facility — its orientation, insulation, lighting, HVAC, and solar potential — affects both operating costs and emissions. For organisations with supply chain sustainability commitments, warehouse strategy needs to integrate environmental performance from the outset, not treat it as a retrofit.

Construction costs remain elevated. Building a new warehouse, or fitting out an existing shell, is substantially more expensive than it was three years ago. Material costs, labour shortages in the construction industry, and longer approval timelines all contribute. This means every design decision carries more financial weight, and the cost of getting it wrong — overbuilding, underspecifying, or choosing the wrong location — is higher than it's been in a long time.

Connecting Network and Warehouse Decisions

One of the most common structural problems we see is a disconnect between network-level decisions and facility-level decisions. The network team models the optimal number and location of DCs. The property team goes and finds buildings. The operations team then has to make whatever they've been given actually work. Each group is doing sensible things in isolation, but the lack of integration means the result is suboptimal.

A centralised network with one or two large facilities might call for a high-throughput, automated warehouse with significant investment in materials handling equipment. A decentralised network with several regional facilities might favour smaller, more flexible operations with lower automation and greater reliance on labour. If the network configuration and the warehouse design aren't aligned, you end up with facilities that are either over-engineered for the flows they handle or under-equipped for the volumes they need to process.

At Trace Consultants, we deliberately run network and warehouse design modelling in parallel. The network model tells us the optimal flows, and the warehouse design work tells us what it takes to process those flows operationally. The two inform each other iteratively until we arrive at a solution that works on paper and will work in practice.

This integrated approach also extends to transport. Dock door numbers, yard layout, staging space, and dispatch scheduling all depend on the outbound transport plan — which in turn depends on the network configuration. Similarly, inbound logistics — container receival, cross-dock operations, putaway sequencing — need to be designed around the reality of how product arrives, not an idealised assumption.

The Role of Data — and Its Limits

Network design and warehouse strategy both depend heavily on data: demand data, order profile data, SKU data, transport data, cost data, and facility performance data. Good data enables good modelling. Poor data produces models that look precise but are actually misleading.

The first step in any network or warehouse project should be a thorough data review — cleaning, validating, and enriching the data to ensure it's fit for modelling. This includes understanding what the data does and doesn't capture. Most ERP and WMS systems will give you transactional data, but they rarely capture the nuances that affect warehouse design — things like handling complexity, product fragility, storage requirements, or the real-world constraints that operators deal with every day.

This is why the best network and warehouse design work combines quantitative modelling with qualitative insight. The model gives you the numbers, but experienced operators and site managers give you the context that turns a theoretical optimum into a practical solution. It's also why technology selection — from network modelling tools to WMS platforms — should be guided by what your organisation actually needs, not by what's newest or most feature-rich.

What About 3PL Versus In-House?

For many Australian businesses, the network design question is inseparable from the operating model question: should we run our own warehouses and transport, or outsource to a third-party logistics provider?

There's no universally right answer. In-house operations offer control, visibility, and the ability to invest in capability over time. 3PL arrangements offer flexibility, variable cost structures, and access to scale without capital commitment. Most organisations end up with some hybrid — perhaps owning their primary DC and using 3PLs for overflow, regional distribution, or specialised services.

What matters is that the operating model decision is made in the context of the network strategy, not independently of it. A poorly structured 3PL arrangement can erode the benefits of an optimised network, while a well-designed outsourcing model can extend the network's reach without proportional cost increases. Trace Consultants helps organisations evaluate insource versus outsource options as part of the broader network design process, ensuring the operating model supports the strategy rather than constraining it.

Resilience: The Dimension That's Easy to Forget

Most network design exercises focus on cost and service — and rightly so, since these are the primary performance dimensions. But the events of the past five years have taught us that resilience deserves equal attention.

A network that's optimised purely for efficiency can be dangerously fragile. A single DC serving the entire east coast is efficient right up until it's affected by flooding, fire, industrial action, or a pandemic-related shutdown. At that point, the cost of disruption far exceeds whatever savings the centralised model delivered.

Building resilience into network design means designing for redundancy where it matters — whether that's maintaining safety stock in a secondary location, designing facilities that can flex capacity, or structuring supplier and transport contracts to enable rapid redirection. Trace Consultants' resilience and risk management practice helps organisations stress-test their networks against realistic disruption scenarios and build contingency into their supply chain architecture.

How Trace Consultants Can Help

At Trace Consultants, we see network design and warehouse strategy as two halves of the same strategic coin. Our approach brings them together into an integrated process that delivers clear, quantified recommendations aligned with your commercial objectives.

Here's what that looks like in practice:

Rapid diagnostic and cost-to-serve analysis. We start with a sharp review of your demand flows, service promises, and current cost structure to identify the two or three levers that will have the greatest impact. This work gives leadership a clear picture of where the opportunities are before committing to a full design programme.

Scenario-based network modelling. We model multiple network configurations — varying facility count, locations, and inventory posture — and quantify the transport, warehousing, and inventory implications of each. We include emissions estimates and risk stress-tests so decisions are robust, not just efficient. Our strategy and network design team brings deep experience across retail, FMCG and manufacturing, government and defence, and health and aged care sectors.

Warehouse strategy and design. We develop layout options, storage media recommendations, process designs, and automation roadmaps tailored to your operational reality. Workforce requirements and safety are embedded from the start, not bolted on at the end. Our warehousing and distribution practice has helped organisations achieve significant reductions in warehouse operating costs and meaningful improvements in throughput and fulfilment accuracy.

Implementation support. Strategy without execution is just a slideshow. We stay involved through property fit-out, process change, systems implementation, and project and change management to ensure that what's designed on paper translates into real-world performance.

Independent, solution-agnostic advice. We don't sell property, equipment, or software. Our recommendations are shaped entirely by your operational requirements and strategic objectives. That independence is what allows us to give advice that genuinely serves our clients' interests.

The Stakes Are Higher Than They Look

Network design and warehouse strategy decisions lock in a significant portion of your cost base and service capability for years. In an environment where industrial property is tightening, construction costs remain high, customer expectations continue to rise, and the competitive landscape shifts fast, these decisions deserve more rigour than they typically receive.

The organisations that approach this work systematically — starting with strategy, grounding decisions in data, modelling scenarios, integrating network and facility design, and planning for resilience — will build supply chains that perform today and adapt tomorrow. Those that make property decisions opportunistically, design warehouses in isolation from the network, or skip the analytical work will find themselves locked into suboptimal configurations that are expensive to unwind.

If your network was designed for a different era — fewer channels, different volumes, a different cost environment — it's probably costing you more than you realise. And with the Australian industrial market heading into a tightening cycle, the window to act on better information is closing.

Trace Consultants can help you see clearly, decide confidently, and move quickly. We keep it practical, transparent, and focused on outcomes your board, your operations team, and your customers will recognise.
