Australia enters a period of energy uncertainty in a position of structural weakness. With less than five weeks of domestic petrol and diesel reserves on hand, the nation faces a straightforward arithmetic problem: if imports stop, the country will run out within 30 to 36 days.
This reality is no longer theoretical. Rural and regional areas are facing "real and unacceptable shortages" of fuel, a ripple effect of the US-Israel war with Iran that has caused global oil prices to surge. Between late February and mid-March, average petrol prices have shot up nearly 50 cents a litre across Australia's five largest capital cities. In response, Australians have hoarded fuel, creating supply chain bottlenecks that the government is struggling to manage.
Energy Minister Chris Bowen has taken a series of emergency measures. The government will be temporarily lowering fuel quality standards for 60 days to allow higher-sulphur fuel to be sold, which will add roughly 100 million litres to the market each month. Up to 762 million litres of petrol and diesel will be released from domestic reserves. Yet Bowen has also been explicit about the limits of government action: the extra fuel will not flow immediately due to supply chain complexities, with the minister noting "it's not like they can just press a button and get fuel out the door, but it will make a difference going forward".
The underlying vulnerability is structural. The country used to have eight oil refineries but that number has dwindled to just two — the Viva Energy facility in Geelong, Victoria, and the Ampol Lytton refinery in Brisbane, Queensland — as domestic oil resources are largely exhausted. Australia imports roughly 90 per cent of its oil which it generally takes as refined product from South Korea, Singapore, Malaysia and Taiwan.
The government's case for why this situation is manageable has weakened visibly. Earlier, officials insisted panic buying was the problem, not supply. Now they acknowledge real shortages in regional areas where fuel infrastructure is thin and demand spikes faster than supply can respond. Real pressures on the supply chain have emerged as demand has increased, with demand in the Adelaide terminal rising by 139 per cent.
The opposition and industry critics argue the government should have acted sooner to build domestic reserves and refining capacity. Australia is the only member of the International Energy Agency that does not hold the mandatory 90-day fuel reserve requirement, something the country has failed to meet since 2012, and the goal was downgraded to 50 days. Most IEA members hold an average of 140 days of their previous year's net imports while Australia holds between 50 and 58 days.
Yet the government contends that holding mandatory 90-day reserves would impose ongoing costs on refineries with limited benefit in a modern supply environment where ships arrive regularly and disruptions, though possible, have become less frequent than in earlier decades. Some industry voices argue Australia must rebuild its sovereign fuel storage capacity onshore and maintain reserves that comfortably exceed international minimums and protect and expand domestic refining capability to reduce reliance on imported finished fuels.
What is no longer in dispute is that Australia's current reserves provide a short safety margin. Diesel powers freight, agriculture, mining and construction; petrol keeps essential workers moving; aviation fuel connects cities and regions; without secure and accessible supplies, supermarket shelves will empty, transport will grind to a halt, regional communities will be cut off and emergency services will be compromised.
The fuel crisis illuminates a genuine policy trade-off. Holding larger reserves costs money, imposes carry costs on industry, and reduces supply chain flexibility. Yet having too little leaves Australia vulnerable to events beyond its control—a war in the Middle East, attacks on shipping lanes, or decisions by other nations to restrict exports. Reasonable policymakers disagree on where the balance should sit. What cannot be disputed is that Australia is now operating at the edge of that balance, with the Strait of Hormuz effectively closed and ships carrying one-fifth of global seaborne oil diverted or staying in port.
Farmers and trucking companies need fuel tomorrow, not a policy debate. For them, the question is practical: will supply chains stabilise in time to avoid disrupting the harvest and food distribution? For the government, the challenge is to release enough reserve fuel to ease immediate pressure while resisting calls to abandon minimum standards altogether. And for Australians more broadly, the episode forces an uncomfortable recognition: Australia will not run out of petrol tomorrow, but in a world where a single conflict can immobilise a fifth of global oil trade overnight, relying on luck is not a strategy.
