What's happening with Australia's fuel excise in 2026?
Fuel excise is the federal tax built into the price of every litre of petrol and diesel. It normally rises twice a year in line with inflation, and in early 2026 it sat at 52.6 cents a litre. When conflict in the Middle East pushed oil prices higher, the government brought in cost-of-living relief: from 1 April it roughly halved the excise, taking about 32 cents a litre off the bowser price. On 20 June that relief was extended into July but tapered to a 16 cent cut, lifting the excise to 36.6 cents, so pump prices rose at the start of July. The reduced rate runs until 2 August. From 3 August the full 52.6 cent excise returns, and because GST is charged on top of it, that's expected to add about 18 cents a litre at the pump, or roughly $9 on a 50-litre tank, unless retailers absorb part of the increase. A routine inflation adjustment in early August nudges the rate a little higher again.
