About Costco fuel in Australia

Costco Australia fuel stations are open to current Costco members and consistently price unleaded petrol and diesel below typical metro servos. Pumps usually open before the warehouse, so you can fill up early on the way to work. Prices on this page are gathered from public sources and refresh periodically — always verify on the pump display before you fill.
