Welcome to the FuelRadar weekly fuel report. As we analyse the latest data across the country, motorists are facing a generally upward trend in petrol and diesel prices. With the national average for Unleaded 91 now sitting at 159.15 cents per litre (cpl), it is more important than ever to monitor local cycles and optimise your fueling stops to keep costs down.
Reported fuel prices and forecast
- Widespread Increases: Petrol prices are rising across almost all capital cities and regional centres. Perth experienced the sharpest spike in Unleaded 91, jumping 13.84 cpl (a 9.06% increase) over the past week.
- Melbourne Holds Steady: In stark contrast to the rest of the country, Melbourne's fuel prices remain remarkably stable. Unleaded 91 saw a negligible rise of just 0.69 cpl (0.45%).
- Diesel Trending Up: Diesel and Premium Diesel prices are steadily climbing nationwide, averaging 179.36 cpl and 182.03 cpl respectively, placing additional pressure on transport and trades.
- Regional Variances: Major regional hubs like Newcastle, Wollongong, and the Gold Coast are mirroring capital city hikes. However, Geelong remains a rare pocket of stability, with Unleaded 91 virtually unchanged and E10 prices actually falling by 2.19 cpl.
- Forecast: We anticipate these rising trends to continue across the eastern seaboard over the coming days as the current petrol price cycle pushes toward its peak.

Looking Ahead
Over the next 3 to 4 weeks, we expect to see the current price cycles mature. For drivers in Sydney, Brisbane, and Adelaide, the current rising trend indicates we are rapidly moving toward the peak of the petrol price cycle. If you are low on fuel, topping up now rather than waiting could save you money at the pump.
Melbourne motorists should remain vigilant. While prices have stayed stable this week, historical patterns suggest a market correction could be on the horizon, potentially driving prices up to match neighbouring states. Perth has just experienced a significant jump, meaning prices should slowly begin to discount over the coming weeks as part of its regular cycle.
Diesel drivers across the country should prepare for continued elevated prices. Unlike regular petrol, diesel does not follow a predictable retail cycle, and current wholesale indicators suggest prices will remain firm.
