Petrol prices have jumped 50 cents a litre across Australia since the start of the US-Iran war, and the real problem runs far deeper than the current headlines suggest. Some service stations have run dry. Farmers are being rationed. Regional wholesalers have declared zero supply at key terminals. Yet Australia remains a major energy exporter. The contradiction exposes a strategic failure spanning three decades and both major political parties.
Iran has effectively closed the Strait of Hormuz, a critical passageway that carries 20 per cent of the world's oil supply, following US and Israeli strikes on Iranian military facilities. For most nations, this means elevated prices at the pump. For Australia, it raises a more uncomfortable question: how did an energy exporter with vast oil and gas reserves end up competing frantically for refined fuel from overseas?
More than 90 percent of refined petroleum products consumed domestically are imported, largely from Asian refineries that themselves rely heavily on Middle Eastern crude. This creates a vulnerability that sits two steps upstream in the global supply chain. Australia does not lack oil. It lacks the refining capacity to process its own crude into usable petrol and diesel. This is not a temporary shortage; it is a structural dependency that has been allowed to develop over decades.
The maths are stark. Australia currently holds 36 days of petrol supply, 29 days of jet fuel, and 32 days of diesel. This sounds reasonable until set against the international standard. Australia's current emergency strategic fuel reserve is "non-compliant", and has been since 2012. Member countries of the International Energy Agency are required to hold stocks equivalent to at least 90 days of oil imports, nearly two and a half times Australia's current buffer. When Asian refineries that supply Australia face tightening crude supply, and when panic buying accelerates domestic consumption, that 36-day cushion evaporates quickly.
The response from Energy Minister Chris Bowen has been to assure Australians that supply remains adequate. But reassurance does not match reality on the ground. Danny Kreutzer, founder of Queensland-based fuel transport company Westlink Petroleum, said his requests for fuel from Brisbane-based terminals were virtually cut off in the wake of the Iran war. "We were only getting 10 per cent of our usage," he said. "Eighty per cent of our business is farmers, transport operators and lot feeds". Tamworth-based Transwest Fuels, which supplies more than 2,000 farmers and agricultural customers, has declared it currently has zero petrol supply at Newcastle and Brisbane terminals.
Government action comes too late in the cycle
The government has moved quickly once the crisis became visible. The federal government will relax the Minimum Stockholding Obligation by up to 20 per cent, allowing fuel companies to draw from mandatory domestic reserves to target areas where supply chains are struggling. The government also confirmed a temporary 60-day amendment to fuel quality standards, permitting higher sulphur levels in petrol, expected to unlock an additional 100 million litres per month by allowing fuel originally intended for export to be diverted to the domestic market. Yet these are emergency measures addressing the symptom, not the underlying vulnerability.
The deeper issue is one of strategic location. A crisis in the Persian Gulf affects the refineries in Singapore, South Korea and Japan that produce the petrol, diesel and jet fuel that Australia imports. In response to Hormuz disruption, these refineries face their own tightening crude supply and competing demand from closer buyers, including China. Australia, sitting at the far end of the supply chain, loses purchasing power. Worse, roughly 83 percent of maritime imports move through Indonesian straits, creating a second chokepoint beyond Hormuz.
Where successive Australian governments failed most visibly is in onshore fuel reserves. Under the former Liberal-National Coalition government in particular, Australia's strategic fuel reserves were effectively offshored, with public money spent storing fuel overseas rather than building sovereign stockpiles at home. This decision, made years ago, now looks indefensible. A researcher warned in 2019 that Australia's stockpile of transport fuels was far from adequate. "Unfortunately, the issue persists in 2026".
Competing values and genuine complexity
It would be easy to assign blame purely to one government or one ideology. The reality is more complicated. Australian refineries have closed over recent decades partly because Asian competitors offer cheaper production and transport costs. Holding larger onshore reserves carries a real fiscal cost. Rebuilding domestic refining capacity requires substantial investment and faces competition from established producers elsewhere. These are genuine trade-offs, not simple failures of will.
Some economists argue that Australia's current situation, while uncomfortable, reflects rational market economics rather than vulnerability. Australia sources most of its refined petroleum products from Singapore, which imports around 80 percent of supplies from the Middle East. As a result, Australia has next to no oil independency. But this dependency worked smoothly during years of stable global supply. The current crisis shows what happens when that stability breaks.
Others note that Australia remains a net energy exporter, with vast gas reserves. Australia imports roughly 90 percent of its liquid fuel, but world crude oil prices have a direct impact on pump prices. In theory, Australia could use export earnings to secure fuel supplies at elevated prices. In practice, during a global shortage, prices rise everywhere simultaneously, and smaller nations lose competitive advantage.
What now
The government's emergency measures will likely stabilise supply in the near term. Analysts forecast regular unleaded petrol prices could soar close to $3.50 a litre, but the alternative to market pricing is rationing, which governments have so far avoided. Panic buying will eventually subside once consumers realise supply is not actually ceasing.
But the structural problem remains. Australia needs transparent reporting of usable, onshore fuel stocks, expanded multi-fuel storage capacity, and regional fuel security partnerships with countries such as New Zealand, Vietnam and Malaysia to build shared reserves and mutual emergency arrangements. Whether government will commit to such measures once the headlines fade is uncertain. Both major parties have allowed this vulnerability to develop. Neither has a compelling track record on reversing it.
The Iran conflict is not Australia's war. But its consequences are immediate and visible. That alone should trigger a sober reassessment of whether a wealthy, energy-rich nation can indefinitely rely on complex global supply chains for basic economic inputs. The case for greater fuel sovereignty is not ideological. It is prudential.
