Why Petrol Prices Are Changing in July, and How to Spend Less at the Servo

If your fill-up cost changed in July, you are not imagining it. The temporary cut to the fuel excise was wound back over the month, and that flows straight through to the price on the board. Here is what actually changed, why not every servo moved at once, and five things you can do to spend less right now.

What changed on 1 July?

The government had been running a larger fuel excise reduction from April to June. From 1 July that was partly restored, leaving a 16 cent per litre reduction in place until 2 August 2026. In plain terms, some of the tax relief on every litre came off, which nudges the base price up.

Why didn't every servo change its price at once?

Fuel moves through the supply chain at different speeds. A servo still selling fuel it bought earlier at the old rate may hold its price for a while, while others update sooner. Wholesale prices, existing stock and individual retailer decisions all play a part. The ACCC notes that changes do not always show up at the bowser immediately.

What else affects petrol prices?

Excise is only one piece. Australian pump prices are also driven by international refined fuel prices, the price of crude oil, the Australian dollar against the US dollar, and how much competition there is near you. When the dollar falls or global prices rise, we feel it locally regardless of the local tax setting.

What are petrol price cycles?

In the big capitals, Sydney, Melbourne, Brisbane, Adelaide and Perth, prices tend to move in cycles. They can jump sharply over a day or two, then drift down gradually over the following weeks before the next spike. Learning your city's cycle helps you fill up nearer the bottom than the top.

Five ways to reduce your fuel costs now

• Use a comparison app. Check live prices near you before you drive, not after.
• Time the cycle. Fill up when prices are near the low point of your city's cycle.
• Do not chase tiny savings. Driving across town to save two cents a litre usually costs more in fuel than you save.
• Combine trips. Fewer cold starts and less backtracking means less fuel burned overall.
• Check your tyres. Underinflated tyres use more fuel. A quick top-up to the right pressure helps.

What happens after 2 August?

The July relief was scheduled to end, with the fuel excise returning to its standard rate from 3 August 2026. That means the small saving from the remaining relief comes off. If government policy changes after that date, check an official source for the latest position rather than relying on older articles.

You cannot control global oil prices or the exchange rate, but you can control when and where you fill up. Compare prices before you go, and always weigh a cheaper price against the cost of driving further to get it.
