Australia's 2026 fuel crisis: what Adelaide drivers need to do before 1 July
Petrol prices surged after the Iran war shut the world's busiest oil shipping route. The federal government halved the fuel excise as a stopgap, but it ends on 30 June. Here is the plain English picture, and the practical things Adelaide drivers can do now (and next time) to soften the blow.
Quick read
The war between the US-Israel coalition and Iran started on 28 February 2026 and choked off the Strait of Hormuz, where around 25% of the world's seaborne oil passes through. Australia imports about 84% of its fuel, so prices spiked. From 1 April, the government cut fuel excise from 52.6 to 20.6 cents per litre, with the states agreeing to a top-up, saving drivers around 32 cents per litre (plus GST) at the bowser.
That cut ends 30 June 2026. Unless extended, pump prices will jump back overnight on 1 July.
Do this now:
- Fill up before 1 July at a cheap suburb (use the RAA fuel map or Petrolmate app)
- Check your tyre pressure this week (saves up to 5% on fuel)
- Combine errands into one trip, not three
- Ease off the accelerator (gentle driving saves 15-20% in city traffic)
- Do not panic buy or stockpile fuel at home, it is dangerous and makes shortages worse
What happened
On 28 February 2026, the war between the US-Israel coalition and Iran began. Within days, Iran restricted shipping through the Strait of Hormuz, the narrow waterway between Iran and Oman that carries roughly 25% of the world's seaborne oil trade and about 20% of global liquefied natural gas. The International Energy Agency called the disruption "the largest supply disruption in the history of the global oil market".
Australia only has two operating oil refineries (Ampol's Lytton in Brisbane and Viva Energy's Geelong plant), and together they cover less than 20% of national demand. The rest comes from refineries in Singapore, South Korea and Malaysia, which themselves rely on Middle East crude. When Hormuz closed, Australia felt it within weeks.
By mid-March, average petrol prices in Adelaide had climbed sharply, some service stations in Victoria and NSW ran dry from panic buying, and the federal government released up to 762 million litres of petrol and diesel from domestic reserves. On 30 March, Prime Minister Anthony Albanese announced fuel excise would be halved from 1 April to 30 June. The states then agreed on 2 April to return a portion of their GST windfall, bringing the total saving to about 32 cents per litre (plus GST), or roughly $23 off a 65-litre tank.
The 1 July deadline
The fuel excise cut runs from 1 April to 30 June 2026. From 1 July, the excise reverts from 20.6 to 52.6 cents per litre. Including the lost state GST top-up and adding GST on top, that is close to a 35 cents per litre jump at the bowser. On a 60-litre tank, that is about $21 extra to fill up. The government has not ruled out an extension, but Energy Minister Chris Bowen has said motorists should not expect the relief to be permanent.
Why this keeps happening
Australia has been here before. The 2022 fuel excise cut after Russia's invasion of Ukraine ran for six months and cost the budget about $3 billion. The 2026 cut is three months and costs around $2.55 billion. Each crisis is treated as a one-off, but the underlying setup is the same: Australia imports the vast majority of its fuel, holds far less in reserve than the IEA's recommended 90 days, and has steadily lost refining capacity over the last two decades. Until that changes, every overseas supply shock lands directly at the local petrol pump.
What you can do to soften the next shock
You cannot fix global oil supply, but you can absolutely cushion yourself from it. Most of these are zero-cost, and they compound. The official infrastructure.gov.au fuel saving tips page is the source for most of these.
1 Inflate your tyres
Underinflated tyres can add up to 5% to your fuel use. Your car's correct pressure is on a sticker inside the driver's door frame. Most servos in Adelaide have free air pumps. Five minutes, real savings.
2 Empty the boot
Extra weight costs fuel. The golf clubs, the workshop tools, the box of clothes for the op shop you keep meaning to drop off, take them out. Roof racks and bike racks cause drag even when empty.
3 Drive gently
Hard acceleration and sudden braking are the biggest fuel wasters. Research from the Australian Automobile Association suggests gentle, anticipatory driving improves fuel economy by 15-20% in city traffic and 10-15% on highways. Watch the cars ahead, anticipate red lights, coast where you can.
4 Combine trips
A cold engine uses much more fuel for the first few kilometres. Three separate short trips burn far more than the same distance done in one go.
5 Time your fill-ups
In Adelaide, prices typically dip Monday through Wednesday and spike Thursday and Friday. Use the RAA fuel map or apps like Petrolmate to compare suburbs. The difference between the cheapest and most expensive stations can be over 20 cents per litre.
6 Don't panic buy
RAA's official position during the March 2026 shortages was blunt: panic buying makes shortages worse, queues longer, and prices higher. Buy when you need it, not because of headlines. Storing fuel at home is a serious fire hazard.
7 Think honestly about your next car
SA's $3,000 EV rebate closed at the end of 2024, and the three-year rego exemption only applies to EVs first registered before 30 June 2025. The federal Fringe Benefits Tax exemption on novated EV leases is still active for now, and can save eligible drivers several thousand a year. EVs are not automatically cheaper, depending on your kilometres, charging access at home, and which model. But if you are buying anyway, run the numbers honestly for both petrol and electric, with current Adelaide fuel prices in the spreadsheet.
The bigger picture
Australia's fuel security depends on shipping routes 12,000 kilometres away. The 2022 Ukraine shock, the 2025 Israel-Iran flare-up, and the 2026 Hormuz closure all caused the same scramble. The federal Treasury Laws Amendment Bill 2026 introduced fines of up to $100 million for fuel price gouging, and the 2026 Federal Budget allocated $10 to $14.8 billion for fuel security and resilience, including a planned government-owned reserve. Whether that translates into smoother bowsers next time is the open question.
In the meantime, the levers in your hands are your tyres, your right foot, your boot, and when you fill up. Small habits, real money.
