Costco runs a fuel station at 14 of its 15 Australian warehouses. Each warehouse sets its own price, so what you pay differs from one Costco to the next; the table below ranks them all on today’s price.
The base unleaded grade depends on the state or territory: Unleaded 91 in ACT, SA, VIC and WA; E10 in NSW and QLD. No station sells both, so the ranking compares each station’s own base grade. The stations also sell Premium 98 and diesel.
The fuel stations are for members only: your Costco membership card is scanned at the pump before it will dispense, and you pay by card there, with no cash. All but one of the 14 are open 6am – 9:30pm Monday to Friday (Adelaide 5:30am – 9:30pm). See Costco fuel opening hours for weekends and which stations are open now.
