Fuel Prices in Australia: What You Pay at the Pump and Why
Australia's average retail price for petrol sits at about $1.155 USD per litre, which works out to roughly $4.37 USD per US gallon. In local terms that is around A$1.67 per litre. Diesel runs a little higher at about $1.307 USD per litre. Compared with the global picture, Australia is on the cheaper end: the world average is $1.484 USD per litre, and Australia ranks 42nd out of 170 countries surveyed, meaning fuel here is more affordable than in most developed economies.
What actually drives the price
Three big forces shape what Australians pay: the global crude oil price, the AUD/USD exchange rate, and federal fuel excise. Australia is a price taker on oil. Although it produces some crude and runs only a handful of remaining refineries, the country imports the bulk of its refined petrol and diesel, much of it from Singapore and South Korea. That means the import parity price tracks international benchmarks closely, and the Australian dollar's strength against the US dollar directly moves the landed cost. When the AUD weakens, fuel gets more expensive even if the USD oil price is flat.
Tax is the other heavyweight. The Commonwealth charges a fuel excise on petrol and diesel that is indexed to inflation twice a year, and on top of that the 10% Goods and Services Tax (GST) applies to the whole price, excise included. Together these levies make up a substantial slice of every litre. Unlike some oil-rich nations, Australia does not subsidise pump prices for ordinary motorists; there is no consumer fuel subsidy, only a fuel tax credit scheme for eligible businesses such as heavy transport, mining and agriculture.
The price cycle and where the trend points
Anyone who fills up in Sydney, Melbourne, Brisbane or Adelaide knows the "price cycle" — a recurring pattern where prices spike sharply then drift down over a few weeks before jumping again. These cycles are a feature of the retail market in the larger capitals and are tracked closely by the ACCC and state fuel-price apps. Timing your fill to the bottom of the cycle can save real money.
Over the longer run, Australia's history shows just how much oil and currency swings matter. Since July 2016 the average price has been about $1.049 USD per litre. The record low was $0.676 USD on 4 May 2020, during the early COVID demand collapse when global crude briefly cratered. The all-time high of $1.587 USD came much more recently, on 30 March 2026. That climb from the 2020 trough to a fresh 2026 peak signals an upward trend driven by higher crude, a softer Australian dollar and the steady ratchet of indexed excise.
How Australia compares globally
Australia's prices look modest against import-dependent, heavily taxed markets but high against subsidised oil exporters. For contrast, see crisis-hit pricing in Lebanon, the heavily managed and partly subsidised retail market in India, and resource-rich but logistically challenging economies like Liberia and the DR Congo.

FAQ
Why is petrol more expensive in some Australian cities than others?
Regional and rural areas often pay more because of higher transport and distribution costs, lower competition and slower turnover. Big capitals like Sydney and Melbourne run a discounting "price cycle" that smaller towns do not, so a litre can vary noticeably across the country even though the national average is about $1.155 USD.
Does Australia subsidise fuel for drivers?
No. There is no consumer fuel subsidy at the pump. Prices reflect the global oil price, the AUD/USD exchange rate, federal excise and 10% GST. The only relief is the fuel tax credit, which refunds excise to eligible businesses such as mining, farming and heavy haulage — not to everyday motorists.
Why have Australian fuel prices risen so much since 2020?
The 2020 record low of $0.676 USD per litre reflected a once-in-a-generation collapse in oil demand. Since then crude has recovered, the Australian dollar has weakened against the USD, and fuel excise is indexed to inflation twice a year. Those combined pressures pushed prices to an all-time high of $1.587 USD per litre in March 2026.
