Costco Trading Hours on May Day / Labour Day 2025

Thinking of heading to Costco on May DayorLabour Day? Here’s what you need to know:

• Queensland: All Costco warehouses will be closed on Labour Day, Monday 5 May 2025. This is due to state trading laws for major retailers, so you won’t be able to shop or fill up at the Costco fuel station on the public holiday.
• Northern Territory (May Day): While trading hours are generally deregulated in the NT, Costco typically observes public holiday closures for May Day as well. It’s safest to expect the warehouse and fuel station to be closed, but always check your local store’s details just in case.
• South Australia: On public holidays like Labour Day, Costco Adelaide is closed. This applies to both the warehouse and the fuel station.
• Victoria, New South Wales, ACT, Western Australia, Tasmania: Labour Day falls on different dates in these states. On the respective Labour Day public holidays, Costco stores are usually closed, including the fuel stations. For example, in Victoria, Costco is closed on Labour Day in March.

In summary:
Costco warehouses and fuel stations across Australia are generally closed on May Day/Labour Day public holidays, regardless of the state. Always double-check with your local store for any exceptions, but don’t count on Costco being open for your big shop or cheap fuel on these public holidays.
