Fuel Prices surge after Iran strikes: What it means for Australian motorists
fuel prices are climbing after missile strikes on Iran and retaliatory attacks have effectively closed the Strait of Hormuz, restricting roughly one-fifth of the world’s seaborne crude. Treasurer Jim Chalmers and Energy Minister Chris Bowen moved to steady public concern as queues formed at service stations and some outlets ran short of petrol. Updated 08: 00 ET on March 8, 2026.
Fuel Prices and Australia’s supply picture
The core impact is simple and immediate: expensive oil feeds through into higher motor fuel costs, and those higher costs are being felt as fuel prices rise at the bowser. Australia imports about 90% of its liquid fuel — petrol, diesel and aviation fuel — and most of those products are supplied from refineries in Singapore, South Korea and Japan. That supply chain in turn depends on Middle Eastern crude, and the near closure of the Strait of Hormuz has removed a major artery of seaborne crude, tightening global flows and lifting commodity prices.
Locally, the refining footprint has shrunk: the number of Australian oil refineries has fallen from 12 to two. Both remaining refineries are described as propped up by government support, and two refineries closed during Angus Taylor’s tenure as energy minister. Australia also keeps a strategic reserve of petroleum products, which officials cite as a buffer against immediate shortages of supply.
Availability and price are not the same thing. Expensive oil makes petrol more expensive, but there is no clear and present sign that imports are about to stop. Still, panic-buying at pumps can amplify strain on racks and depots and push fuel prices even higher than the underlying market move.
Immediate reactions
Chris Bowen, Energy Minister, Australian Government, warned motorists directly: “There are real challenges, but there is no need for panic-buying; that will just make the situation worse. ” Treasurer Jim Chalmers sought to reassure Australians that the US-Israeli war on Iran did not mean the nation was about to run out of fuel, framing public comments as an attempt to calm consumer behaviour amid visible shortages at some service stations, including reports of Costco outlets running dry and long queues elsewhere.
Industry officials point to the strategic reserve and existing import channels while acknowledging that higher crude prices translate into higher retail costs. The shrinking local refining base increases reliance on overseas supplies, and that structural shift underpins official concern about economic security even as immediate shortages are not declared imminent.
What’s next
Watch how the government balances the reserve, continued support for the two remaining refineries and diplomatic moves affecting strait access; those factors will determine whether fuel prices stabilise or keep climbing. Officials say there is no present signal that imports will dry up, but motorists and businesses will be monitoring pump conditions and price boards closely over the coming days.
For now, the immediate test will be whether public calm holds and stock at local depots is drawn down steadily rather than in panic bursts that would accelerate price spikes and availability problems. Fuel prices remain the key metric consumers will watch as this situation unfolds.
