Australian motorists are bracing for an increase in petrol and diesel prices as the federal government’s temporary fuel excise discount officially concludes at midnight on August 2, 2026. The measure, which had been in place since April to help shield households from the economic shock of the conflict in the Middle East, will see the full tax rate return to the pump. This change marks the end of a phased withdrawal of support that began in July, when the initial discount was reduced to 16 cents per litre.
The fuel excise is a flat tax on petrol and diesel that serves as a significant source of government revenue, typically used to fund essential services like health and infrastructure. When global oil prices surged earlier this year due to disruptions in the Strait of Hormuz, the government halved the excise to provide immediate relief to families and businesses. While the policy was successful in dulling the impact of record-high fuel costs, officials have consistently maintained that the relief was intended to be a temporary response to an acute crisis rather than a permanent fixture of the tax system.
Treasurer Jim Chalmers confirmed the decision to let the measure expire, noting that the government had deliberately tapered the support to help the economy adjust. While the return of the full excise is expected to push prices up, the Australian Competition and Consumer Commission has been tasked with monitoring fuel retailers to ensure that any price adjustments at the bowser are legitimate and not the result of price gouging. Motorists are advised that while prices may rise, the extent of the increase will vary depending on local market conditions and individual service stations.
