FuelWatch and fuel prices

FuelWatch shows fuel prices in your area so you can choose where and when to fill up.

Prices shown on FuelWatch are the standard cash prices. They exclude discounts and charges, such as supermarket discounts or credit card fees.

Current fuel prices 

The charts below show year-to-date (YTD) daily average retail prices and terminal gate prices (TGP), 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) resulting in the retail margin increasing. It is important to note that it can take days and sometimes weeks for metro fuel retailers (sometimes longer for regional 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.

Unleaded petrol

Chart 1 presents the YTD daily average retail price and average TGP for ULP in the Perth metropolitan area. 

As explained above and as expected, on 1 April 2026, the retail margin increased.

Diesel

Chart 2 presents the YTD daily average retail price and average TGP for diesel in the Perth metropolitan area. 

As expected, the metro daily average diesel retail margin increased on 1 April 2026, but from 3 April 2026 it has narrowed as the daily average diesel TGP have continued to increase sharply.

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.

Using FuelWatch to find fuel prices in your location:

The interactive map shows fuel prices available near you. This makes it easy to find your best fuel deal. Prices are flagged over the map with the lowest price highlighted in red. 

• ‘Search by suburb or postcode’ in the search bar positioned at the top of the screen.
• ‘Use my location’ feature (compass) at the bottom right of the screen. You will need to enable location permission.
• Finger stretching the screen to search all directions of the map.
• The ‘List’ view shows prices displayed on the ‘Map’ view.

Mobile devices can switch between map or list view.

FuelWatch covers metropolitan Perth and many regional areas. A list regional areas covered is available from FuelWatch boundary.

Tomorrow's fuel prices today

Fuel prices for the following day are available from 2:30 pm each afternoon.  This means you can see which day and station is the cheapest before you head to the bowser.

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.

What FuelWatch does

FuelWatch gives Western Australians fuel price transparency and certainty. 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. The prices are then reported on FuelWatch services. Motorists can use FuelWatch to make the best decision on where and when to buy their fuel.
