$60 Gold Star membership entitles you to purchase products at any Costco worldwide for one year. A free Household card is also available for a family member who lives at the same residential address as the Primary member.

Each cardholder can bring in two guests over age 18 years (we do not count children under 18 yrs.) Please note that guests cannot shop or pay for items; only members are able to shop at Costco.

All Primary and Household cardholders must be over the age of 18 and present one piece of photo identity (Drivers Licence, Proof of Age or valid Passport). To validate your membership, a photo must be taken and printed on the card at the warehouse.

To purchase a Gold Star membership, click here to register online. Costco does not hold any credit card details - you will be redirected to Commonwealth Bank's CommWeb. If you encounter any difficulties, please email us at membership@costco.com.au.

Costco Australia cardholders can renew their membership online or at the register when you shop within three months of expiry. The additional household card will also be renewed at the same time. Memberships renewed within 2 months after the expiration of the current membership year will be extended for 12 months from the expiration date. Memberships renewed more than 2 months after such expiration will be extended for 12 months from the renewal date.

If you lost our card, please let us know as soon as you can so we can cancel your card. You can then take a piece of photo ID showing your current residential address along to the membership counter at the warehouse. The membership team will be able to print you a new card.
