Pump prices vary by state: Costco Adelaide posts the lowest regular-unleaded pump at $1.447 (Unleaded 91) while Canberra sits at $1.587 (Unleaded 91) — a $0.140 spread driven by state fuel excise, transport costs, and local competition.

E10 prices have eased about $0.156 over the past month, from $1.656 a month ago. Premium 98 has eased about $0.146 and diesel has eased about $0.307 over the same period.

30-day Australia average price trend

Costco's Australian fuel stations are members-only and consistently price unleaded and diesel below the typical metro servo. It's the same model Costco runs worldwide: fuel is a loss-leader kept on thin margins to draw members onto the site, and the warehouse's buying power lets it undercut the majors. The pumps are usually open before the warehouse itself, so you can fill up early on the way to work.

You need a Costco membership. The pump reads your membership card before it will dispense, so fuel is members-only — and unlike some countries, the Costco Shop Card can't be used for fuel in Australia.

Visa or Mastercard with a PIN — no Amex or cash. At the pump you pay with a Visa or Mastercard, credit or debit, and enter your PIN so the terminal can pre-authorise the card. American Express, cash, the Costco Shop Card, and mobile wallets like Apple Pay aren't accepted at the fuel station, though some of those do work inside the warehouse. Full details are in our Costco Australia fuel payment methods guide.

Unleaded 91, E10, premium 98, and diesel. Most sites carry regular unleaded (91), E10, premium 98, and diesel, all priced per litre and listed in the table below. The fuel meets the same Australian fuel standards as any other servo.

Prices change daily and vary by site. Pump prices move with wholesale costs and differ from one location to the next, so the figures on this page refresh daily from public sources. To find your closest store, use our Australian Costco fuel station finder. As always, check the price on the pump display before you fill.
