Bargain hunters, we’ve got good news. Any member of the Costco fan club knows it’s an absolute treasure trove of bulk brilliance: cheese wheels the size of your head, frozen pizzas by the dozen, five-kilogram peanut butter tubs and pet food sacks heavier than your dog – all at way lower prices than your typical Woolies or Coles run. So if you love a cheap deal, perhaps it’s time to sign up – Costco is expanding, with its fifth Victorian warehouse set to open in 2027.
The beloved American bulk retailer made its Aussie debut in 2009 and remains the country’s only subscription warehouse chain, raking in an estimated $5 billion in annual sales. Costco currently operates 15 stores across Australia, including four each in Victoria and NSW, three in Queensland, two in Western Australia, and one in both South Australia and the ACT. Earlier this year, the membership-based giant unveiled its newest $118 million warehouse in Melbourne’s western suburbs, with eager shoppers queuing for hours to be among the first inside. And Costco is showing no signs of slowing down.

Now, the brand has revealed plans for its fifth Victorian warehouse – a $74m superstore and mega fuel station in Pakenham, slated to open in 2027. Outside of Victoria, the bulk-buy giant will open its 17th Aussie store in Perth’s northern suburbs at the new $33 million Alkimos Central Home X Trade Hub. Construction on the first stage of the homemakers precinct is expected to begin later this year, with the store also scheduled to open in 2027.
