Costco Fuel Prices in Perth
The Perth Airport Costco (142 Dunreath Dr) is selling Unleaded at 156.7c per litre as of Jul 19, 2026. WA has a rule the rest of the country doesn't: under FuelWatch, every station locks its price for the whole day and publishes it the afternoon before — so today's Costco price was knowable yesterday, and tomorrow's is out by early evening.
