Costco: Labour Day / May Day Opening Hours 2026

Labour Day / May Day (Monday, 4 May)

Costco members in Queensland must plan ahead, as warehouses (such as those in North Lakes, Ipswich, and Coomera) will be closed in observance of the Labour Day public holiday restrictions. Please note that Costco does not currently operate any warehouses in the Northern Territory. For members in all other states including New South Wales, Victoria, South Australia, and Western Australia, warehouses will be fully open and operating on their standard Monday schedules.
