Motorists in Perth and Mandurah are advised to fill up now if they need to, with petrol and diesel prices set to rise tomorrow.
Wholesale price increases, driven by higher international benchmarks, are now flowing through to local pump prices. However, buying regular unleaded petrol (ULP) from the cheapest site in Perth rather than the most expensive, a difference of 64 cpl, means motorists can potentially save $38 on a 60-litre tank.
FuelWatch reports that, from 6am tomorrow (Wednesday 11 March 2026), the average price of Perth’s ULP will increase by 28 cents per litre (cpl) to 222.6 cpl with BP hiking up to 245.9 cpl; EG Ampol up to 235.9 cpl; Ampol up to 234.9 cpl; Caltex and Reddy Express up to 229.9 cpl; 7-Eleven up to 219.9 cpl; Vibe up to 213.5 cpl; and United up to 209.9 cpl.
Despite the average hike tomorrow, there are still 21 individual sites offering ULP below 196 cpl, so consumers should check the FuelWatch website to find the lowest price near them.
Tuesday’s cheapest ULP is available for:
- 174.0 cpl at Shell Bullsbrook in the East;
- 172.7 cpl at Costco Casuarina and Costco Perth Airport (membership required) and 179.3 cpl at Burk Cannington and Burk Oakford in the South; and
- 175.5 cpl at Liberty Landsdale in the North.
Wednesday’s cheapest ULP will be available for:
- 194.9 cpl at Hills Emporio in the East;
- 184.7 cpl at Costco Casuarina and Costco Perth Airport (membership required) and 187.3 cpl at Burk Cannington in the South; and
- 193.5 cpl at Better Choice Edgewater in the North.
Diesel prices continue to increase. Tomorrow's metro average will be 242.2 cpl, however there will be over 25 Perth sites selling below 220 cpl.
