The Australian Competition and Consumer Commission (ACCC) is actively examining the impact of international crude oil prices on domestic fuel prices in Australia, particularly in light of recent geopolitical tensions in the Middle East. Commissioner Anna Brakey emphasized that while local petrol retailers cannot control international costs, they must not make false or misleading statements regarding price increases, as this would violate Australian Consumer Law.

The ACCC has communicated its expectations to major fuel companies regarding domestic pricing strategies as the situation evolves. Consumers are encouraged to utilize fuel price apps to find the best deals available.

Recent reports indicate that average retail petrol prices in major Australian cities rose slightly in the December quarter of 2025, although they were lower overall compared to 2024. The average price across the five largest cities was recorded at 180.4 cents per litre, reflecting a minor increase from the previous quarter.

Factors contributing to the rise in prices include higher retail costs and margins, as well as certain wholesale costs. The ACCC's monitoring also revealed that while crude oil prices trended downward during the December quarter, international refined petrol prices remained relatively stable.

In addition to petrol, diesel prices also saw an increase across all capital cities, with average retail diesel prices rising to 185.9 cents per litre. Meanwhile, electric vehicle sales reached a record high in December 2025, accounting for nearly 17 percent of all new vehicle sales.

As part of its ongoing oversight, the ACCC has been directed by the Treasurer to monitor petroleum prices, costs, and profits for an additional five years, with quarterly reports required.
