Australian motorists are now paying approximately 20 cents more per litre for petrol following the federal government’s decision to reinstate the full fuel excise from August 1, 2026. This move, which saw the excise return to its original 53 cents per litre, marks the end of a temporary discount introduced earlier this year to alleviate cost-of-living pressures.

The reinstatement means an immediate increase in daily running costs for millions of households and businesses across the country, directly impacting August 2026 fuel budgets.

The Return of the Full Fuel Excise

The temporary reduction in the fuel excise was initially implemented in April 2026, a measure taken by the government amidst global energy market volatility spurred by geopolitical events, including the Iran war and issues concerning the Strait of Hormuz. The discount was designed to provide relief at the bowser, effectively reducing the federal government’s take on every litre of fuel sold.

However, Energy Minister Chris Bowen stated that Australians should not be surprised by the return of the full excise, emphasising that it was always communicated as a temporary measure. This aligns with the government’s long-standing position that such relief packages are not sustainable in the long term.

“I think Australians have understood as we made crystal clear all the way through this was a temporary measure.” — Chris Bowen, Energy Minister (August 1, 2026)

Immediate Impact on Petrol Prices

For many motorists, the price increase was felt almost immediately, with some service stations adjusting their prices even before the official August 1 deadline. With the excise now fully restored, a tank fill-up that previously cost around AUD 1.99 per litre for Octane-95 on August 3, 2026, is now significantly higher. This translates to an additional AUD 10 for a typical 50-litre tank of fuel.

Historical data from GlobalPetrolPrices.com shows that the average gasoline price in Australia between August 2016 and August 2026 was AUD 1.53 per litre. The current price of AUD 1.99 per litre on August 3, 2026, already reflects a 15% increase from one month prior (AUD 1.73/litre) and an 8.2% increase from three months prior (AUD 1.84/litre). The maximum price recorded in this period was AUD 2.30 per litre on March 30, 2026.

This latest increase pushes pump prices closer to the higher end of historical ranges, placing renewed pressure on household budgets already grappling with broader cost-of-living challenges.

Broader Economic Considerations

The reinstatement of the fuel excise is a critical factor for inflation and consumer spending. Higher transport costs can flow through to the prices of goods and services, as businesses face increased expenses for logistics and operations. While the government’s intention was for the discount to be temporary, its removal at a time when many Australians are still feeling financial strain could have ripple effects across the economy.

For some households, managing these increased fuel costs might involve reviewing overall energy consumption. While separate from petrol, understanding and optimising home energy usage can offer avenues for savings.
