Building Northern Resilience: Why Australia's Supply Chain Strategy Needs a Geographic Reset
The Hormuz crisis has focused national attention on a single chokepoint. That is understandable. The closure of the strait has removed roughly 20% of global oil supply from the market, triggered the largest coordinated release of strategic petroleum reserves in history, and pushed Australian fuel prices to record levels. But focusing on Hormuz alone misses the deeper structural lesson.
Australia's fuel security, and its broader supply chain resilience, does not depend on one chokepoint. It depends on a chain of maritime chokepoints stretching from the Persian Gulf through the Indian Ocean to the Indonesian archipelago. The Strait of Hormuz. The Strait of Malacca. The Lombok Strait. The Sunda Strait. These waterways carry the vast majority of Australia's maritime trade: roughly 83% of imports and 90% of exports transit through Southeast Asian sea lanes.
Hormuz is the first link in that chain to break. The question that government, defence, and infrastructure leaders should be asking is not "how do we respond to this crisis?" It is "what happens if the next disruption is closer to home?"
This article examines the layered geographic vulnerability of Australia's supply chains, the case for a deliberate northward shift in resilience infrastructure, and the practical supply chain planning that government, defence, and critical infrastructure operators should be undertaking now.
The Chain of Chokepoints: Australia's Layered Vulnerability
The standard framing of Australia's fuel vulnerability focuses on import dependency: Australia imports roughly 90% of its refined fuel, has only two operating refineries, and holds reserves well below the International Energy Agency's 90-day standard. All of that is true, and all of it matters. But it is only the first layer.
The second layer is the refinery dependency. Australia does not import crude from the Gulf in significant volumes. It imports refined products from Asian refineries in Singapore, South Korea, and China. Those refineries depend on Gulf crude. So the Hormuz disruption hits Australia indirectly, through the refining system that sits between the Gulf and Australian fuel terminals. That creates a lag (the subject of the first article in this series) but it also creates a concentration risk: a small number of refining hubs, located in a small number of countries, processing crude from a single dominant supply region.
The third layer, and the one that has received the least attention, is the geographic corridor through which refined products reach Australia. Every tanker, container ship, and bulk carrier arriving at an Australian port from Asia transits through the narrow waterways of Southeast Asia. The Malacca Strait is 1.5 miles wide at its narrowest point and carries the highest concentration of commercial shipping of any waterway on earth. The Lombok and Sunda straits are the primary alternatives, but they are not wide-open ocean: they are defined corridors with their own navigational constraints and geopolitical contexts.
If a disruption in the Middle East were to coincide with, or trigger, disruption in Southeast Asian sea lanes, whether through state-level coercion, grey-zone activity, piracy escalation, or broader regional conflict, Australia would not simply face expensive fuel. It would face physically constrained access to refined products, containerised goods, and industrial inputs. The rerouting options are limited: sailing around Australia's south adds days to every voyage and does not solve the problem of constrained origin-end loading.
This is not a theoretical scenario. The 2023 Defence Strategic Review warned explicitly that Australia's assumed strategic warning time had eroded. The current crisis is demonstrating in real time how quickly maritime disruption can cascade through supply chains. The lesson is that resilience planning needs to account for disruption at any point along the maritime corridor, not just at the most distant chokepoint.
The Case for a Northern Shift
Australia's current fuel and supply chain infrastructure is concentrated in the south and east. The two operating refineries are in Brisbane and Geelong. The major fuel import terminals are in Sydney, Melbourne, Brisbane, and Fremantle. The national fuel distribution network is designed to flow product from these coastal terminals inward by road and rail.
This configuration works when the supply chain is functioning normally. It is structurally vulnerable when it is not. If imports through Southeast Asian sea lanes are constrained, southern and eastern terminals are the last to receive supply, because they are the furthest from the origin of inbound shipping. Northern Australian ports, by contrast, are geographically closer to alternative supply corridors and to the Pacific routes that bypass Southeast Asian chokepoints entirely.
ASPI has argued that the centre of gravity in Australia's fuel security debate must shift north. The logic is straightforward: distributed fuel resilience requires storage, terminal capacity, and distribution infrastructure positioned across the continent, not concentrated in the population centres of the southeast. Larger northern storage facilities, greater redundancy in import terminals, and expanded capacity to move fuel across the continent during disruption would all materially improve Australia's ability to sustain operations under constrained supply.
This is not solely a fuel argument. The same geographic logic applies to defence logistics, critical mineral processing, food distribution, and industrial supply chains. Northern Australia is closer to allied staging areas, closer to emerging Indo-Pacific trade corridors, and better positioned to receive supply from diversified sources (including the United States, which is now shipping emergency fuel to Australia on 55 to 60-day voyages from the Gulf Coast). Infrastructure investment in the north serves multiple strategic objectives simultaneously: fuel security, defence readiness, economic development, and supply chain diversification.
What Government Agencies Should Be Doing Now
The National Fuel Security Plan agreed by National Cabinet on 30 March 2026 addresses the immediate crisis: emergency reserve releases, fuel quality standard relaxation, Export Finance Australia underwriting for additional cargoes, and a national fuel supply taskforce. These are necessary short-term measures. But the crisis has exposed structural weaknesses that short-term measures cannot fix.
Rethinking strategic reserves
Australia uses more energy from diesel alone than from electricity. Yet the country has failed to meet the IEA's 90-day reserve requirement since 2012. Current reserves of approximately 30 to 39 days provide a narrow buffer that is adequate for short disruptions but wholly inadequate for a sustained closure measured in months. The Hormuz crisis should accelerate investment in the Boosting Australia's Diesel Storage Programme and expand its scope to include northern and remote storage facilities capable of supporting defence, mining, and agricultural operations during prolonged disruption.
Building distributed terminal capacity
The current fuel distribution model relies on a small number of major import terminals. If any of those terminals becomes inaccessible (due to disruption, infrastructure failure, or capacity saturation during a supply surge), there is limited redundancy. Investment in additional terminal capacity, particularly in northern Australia and along the western coast, would provide alternative entry points for fuel imports and reduce the concentration risk inherent in the current network.
Mapping n-tier supply chain dependencies
Government procurement frameworks typically manage direct supplier relationships. The Hormuz crisis has demonstrated that the critical vulnerabilities often sit two or three tiers upstream: the refinery that processes the crude, the shipping line that carries the cargo, the insurance market that underwrites the voyage. Government agencies need to build n-tier supply chain maps for critical categories (fuel, fertiliser, medical supplies, defence materiel, food distribution) that identify chokepoint dependencies and concentration risks across the entire supply chain, not just the direct contract.
Fixing procurement contract frameworks
As discussed in earlier articles in this series, many government procurement contracts lack effective fuel escalation mechanisms, or contain no provision for cost escalation beyond annual CPI review. This is a structural weakness that predates the current crisis but is now causing real operational consequences: suppliers absorbing cost increases they cannot sustain, which will eventually lead to service degradation, variation claims, or supplier failure. The crisis should trigger a systematic review of procurement contract templates across Commonwealth and state agencies, with specific attention to fuel and energy cost escalation, force majeure provisions, and change-in-law clauses linked to the Liquid Fuel Emergency Act.
Integrating fuel security into defence logistics planning
The Australian Defence Force's fuel requirements are significant and operationally critical. The current crisis has reinforced the case for accelerating defence-grade energy systems that reduce reliance on imported petroleum, including synthetic fuels, hybrid energy systems for bases, and distributed fuel storage positioned for operational flexibility rather than peacetime efficiency. Defence logistics planning must assume that fuel supply disruption is a feature of the operating environment, not an exceptional event.
What Critical Infrastructure Operators Should Be Doing
Airports, ports, hospitals, water utilities, telecommunications networks, and energy generators all depend on liquid fuel, whether for primary operations, backup power, or logistics. The Hormuz crisis is a stress test for their supply chain resilience, and the results should inform investment decisions for the next decade.
Audit your fuel supply agreements. Do you have a direct supply agreement with a major fuel distributor that provides priority allocation during constrained supply? Or are you purchasing on the spot market, where you will be lowest priority in a rationing scenario? The difference matters enormously when supply tightens.
Test your backup power assumptions. Many critical facilities rely on diesel generators for backup power. The assumption is that fuel will be available to run them. In a sustained supply disruption, that assumption may not hold. What is your generator runtime at current fuel stocks? What is your resupply plan if fuel deliveries are delayed by days or weeks?
Map your logistics dependencies. Every item that arrives at your facility by truck carries a diesel cost. In a rationing scenario, your suppliers' ability to deliver may be constrained before your own operations are directly affected. Understanding which suppliers operate their own fleets (and have fuel security) versus those that rely on third-party logistics (and are more vulnerable to rationing) is critical planning information.
Stress-test your continuity plans against the current scenario. Most business continuity plans model short-duration disruptions: a 48-hour power outage, a one-week supply interruption. The Hormuz crisis is a multi-month event with uncertain duration. Does your continuity plan account for sustained cost escalation, supplier financial distress, and potential rationing of a critical input? If not, it needs to be updated.
The Longer View: From Crisis Response to Structural Resilience
Australia's geographic advantage, the vast distance that insulates it from most conflicts, has been treated as a substitute for resilience rather than a means of building it. The Lowy Institute has argued that comfort has diluted discipline: because supply chain dependency did not produce a lasting crisis during COVID, it was treated as acceptable. The current crisis is making the costs of that complacency visible.
The structural reforms required are not new ideas. Fuel reserve expansion, domestic refining support, distributed storage, northern infrastructure investment, procurement framework modernisation, and defence logistics transformation have all been discussed in policy circles for years. What the Hormuz crisis provides is the forcing function: the real-world demonstration that these investments are not theoretical hedges against improbable scenarios, but operational necessities for a country that imports 90% of its refined fuel through a chain of contested maritime corridors.
Every oil shock in modern history has generated a proportional policy response. The 1973 embargo accelerated France's nuclear programme. The 1979 Iranian Revolution drove Japan's energy efficiency transformation. The question for Australia in 2026 is whether this crisis will be the catalyst for genuine structural investment in supply chain resilience, or whether, as has happened before, the urgency will fade once prices moderate and the tankers start flowing again.
The organisations and agencies that use this moment to build resilience, not just respond to the crisis, will be the ones best positioned for whatever comes next. And something will come next. The geography of risk has not changed. Only the awareness of it has.

Where to Begin
The Hormuz crisis will end. The maritime geography that makes Australia vulnerable will not. The chain of chokepoints from the Persian Gulf to the Indonesian archipelago will remain, and the question of whether Australia has the distributed infrastructure, diversified supply corridors, and resilient procurement frameworks to withstand disruption at any point along that chain will persist long after oil prices moderate.
The time to invest in structural resilience is when the cost of not doing so is fresh in memory. That time is now.
