FuelWatch shows fuel prices in your area so you can choose where and when to fill up.
Fuel retailers must notify FuelWatch of their next day's prices by 2pm each day. These prices are ‘locked in’ for 24 hours from 6am the following day. FuelWatch makes the following day's prices available to the public by 2:30pm each day.
Prices shown on FuelWatch are the standard cash prices. They exclude discounts and charges, such as supermarket discounts or credit card fees.
The FuelWatch scheme will be expanded to include every fuel retailer in Western Australia from 1 May 2026.
Using FuelWatch to find fuel prices
Prices are flagged over the map with the lowest price highlighted in red. This makes it easy to find your best fuel deal near you by:
- searching by suburb or postcode
- using my location feature (compass). You will need to enable location permission.

Tomorrow's fuel prices today

FuelWatch price trends tracks fuel prices so you can see if prices are trending up or down.
Current Perth fuel prices
The charts for Perth below show year-to-date (YTD) daily average retail prices and terminal gate prices (TGP). TGP are an indicator of average wholesale prices.
The difference between the retail and TGP price shows the retail margin. Retail margins are used as a guide to profit margins but is not actual profits as operating costs have not been taken into account.
On 1 April 2026, the fuel excise on petrol and diesel was reduced by 32 cents per litre (cpl). It is important to note that it can take days and sometimes weeks for metro fuel retailers to deplete their current stocks that were subject to the full excise and replenish with a new wholesale delivery that includes the excise cut — this is a reason for retail margins increasing on 1 April 2026. Based on FuelWatch analysis, most, if not all, Perth petrol and diesel retailers have fully passed on the excise cut by mid-April 2026.
Unleaded petrol
Chart 1 presents the YTD daily average retail price and average TGP (cents per litre) for ULP in the Perth metropolitan area.
As explained above and as expected, on 1 April 2026, the difference between the daily average ULP retail price and TGP (ULP retail margin) expanded. From 8 April 2026, considering the returned weekly petrol price cycle, the ULP retail margin contracted and by the second week of April 2026, the ULP retail margin was below historical averages and even dipped into negative territory in late April and early May 2026.
Diesel
Chart 2 presents the YTD daily average retail price and average TGP (cents per litre) for diesel in the Perth metropolitan area.
Time for retailers to pass on savings from the excise cut, as explained above, is a reason for the difference between the daily average diesel retail price and TGP (diesel retail margin) expanding at the start of April 2026. From April 2026 to date, the diesel retail margin has contracted and expanded a number of times as the TGP dropped sharply and levelled out a number of times. The diesel retail margin is currently well below historical averages.
Fuel price inspections
Extra checks will be carried out at fuel stations in the FuelWatch boundary across WA over the next several weeks. These checks will make sure:
- fuel is being sold at the correct price notified to FuelWatch
- fuel prices are clearly and correctly displayed.
Fuel station operators who do not follow the rules may receive warnings, fines, or even face prosecution.
Fuel prices in Australia
The Government (Commonwealth, State or Territory) does not set or control fuel prices in Australia.
Fuel prices go up and down for many reasons including:
- changes to international benchmark prices;
- the value of the Australian dollar to the US dollar;
- local competition and the daily pricing decisions made by wholesalers and retailers.
The Australian Competition and Consumer Commission (ACCC) has more information.
Petrol price cycles in the rest of Australia
Petrol price cycles in the Eastern state capital cities vary in size and length. Eastern states’ drivers also face price changes during the day. This makes it difficult to compare stations and get the cheapest fuel. For information on petrol price cycles in the Eastern states visit the ACCC’s website.
