Transport operators unable to absorb diesel costs are being forced to park their trucks, according to industry leaders warning of economic collapse if the fuel crisis deepens. The Middle East conflict has already caused a 70% rise in fuel costs since early March, creating a crisis that extends far beyond the bowser to every aspect of Australia's supply chain.
National average unleaded petrol reached 219.5 cents per litre for the week ending March 15, with diesel climbing to 245.6 cents per litre, including isolated reports of $3 per litre in parts of Sydney's northern beaches. The National Road Transport Association warned that rising fuel prices are set to force heavy vehicle fleets off the road, resulting in grocery price spikes and empty supermarket shelves by mid-April.
The cost of fuel has to be worn by the end customer or people cannot actually operate in business; they cannot make their contracts work, according to NatRoad CEO Warren Clark. The structural problem is acute: fuel is typically one of the top three costs for a trucking business, and any increase in fuel prices has a big impact. Yet many operators lack the contractual mechanisms to pass those costs on quickly.
The crisis stems from global geopolitics. Iran has effectively closed the Strait of Hormuz, a critical passageway that carries 20 per cent of the world's oil supply. Energy Minister Chris Bowen confirmed on March 21 that six oil shipments bound for Australia in April have been turned back or deferred due to escalating tensions, compounding fears that key Asian suppliers like Malaysia and South Korea may prioritise domestic needs over exports.
Australia's structural vulnerability is undeniable. The country imports roughly 90% of its fuel, mostly as refined product from South Korea, Japan, Singapore, Malaysia and Taiwan. Only two refineries remain after closures, exposing the nation to geopolitical risks. This dependence transforms distant conflicts into immediate domestic pain.
Regional shortages are already acute. Nathan Falvo, a service station owner in Robinvale in Victoria's far northwest, was forced to ration the latest fuel delivery after running completely dry over the weekend, with all three stations in the town introducing a $50 sales limit on what was called one of the fruit bowls of Australia. In New South Wales, Premier Chris Minns reported 107 stations without diesel and 42 completely out of fuel as of mid-March.
The cascade of economic damage compounds by the day. Farmers have sounded the alarm, with National Farmers' Federation president Hamish McIntyre warning food prices could rise by as much as 50 per cent. Farmers burn reserves for tractors, risking crop losses; milk tankers idle and meat processing slows; weekly diesel needs jumped 40 per cent, per distributors.
The government is attempting to manage the crisis. The Australian Competition and Consumer Commission launched a probe into major fuel retailers over alleged anti-competitive conduct, while the government formed a National Fuel Supply Taskforce to coordinate distribution. The International Energy Agency urged conservation measures, calling on Australians to work from home where possible, avoid non-essential air travel and use public transport; Bowen echoed the advice, noting no one-size-fits-all mandate but encouraging voluntary cuts to preserve supplies for essential services like farming, freight and emergency response.
Yet the underlying issue defies quick fixes. Australia's low fuel reserves breach international standards. Australia's uniquely low reserves breach the IEA's 90-day requirement, with defence analysts describing the situation as absolutely pathetic and blaming decades of policy inaction on fuel security. In a world where a single conflict can immobilise a fifth of global oil trade overnight, relying on luck is not a strategy; in an emergency it could take 30 to 40 days to ship crude to Singapore for refining and then transport the fuel back to Australia.
The transport industry has set out demands. The Australian Trucking Association is calling on the Australian and state governments to activate the Disaster Recovery Funding Arrangements immediately to help small trucking businesses, which typically offers cash grants and concessional loans to businesses with fewer than 20 employees. Industry bodies also seek temporary removal of road user charges and amendments to labour law to expedite fuel levy negotiations with major customers.
As March 22 draws to a close, Australia faces a genuine test of economic resilience. The immediate question is not whether transport costs will rise—they have already. It is whether the government can coordinate relief quickly enough to prevent a cascade of small business failures, and whether the broader economy can absorb the shock. If tankers face prolonged delays beyond mid-April, theoretical risks become operational reality.
