Australia's Cheapest Fuel Prices - Wednesday 20 May 2026

Welcome to the FuelRadar national fuel price report for 20 May 2026. As we analyse the latest pricing data across Australia, we continue to see significant volatility in the petrol market. Global crude oil fluctuations and local supply chain factors have led to varying prices at the bowser. This report highlights the cheapest fuel prices currently available to help you optimise your travel budget and make informed decisions.

When comparing prices across the nation, coastal centres generally offer more competitive rates than regional or remote areas. New South Wales and Queensland are currently battling for the lowest average prices, particularly in the E10 and Unleaded 91 categories. Conversely, the Northern Territory and Tasmania remain at the higher end of the spectrum due to elevated transport and logistical costs. Review the state-by-state breakdown below to find the most affordable stations in your local area.

Money-Saving Tips

• Monitor the cycle: Capital cities often follow a distinct petrol price cycle. Aim to fill up when prices hit the bottom of the cycle in your city.
• Choose E10 where possible: If your vehicle is compatible, E10 is frequently the cheapest unleaded option available at the pump.
• Shop around: Prices can vary significantly even within the same suburb. Always check local stations before committing.
• Combine trips: Optimise your daily route to reduce overall fuel consumption and minimise cold engine starts.
