Get ready for a retail revolution: Costco is set to shake up the Australian market with an ambitious plan to open 20 new stores in just five years. But here’s where it gets controversial—can the island state of Tasmania, long overlooked by retail giants, finally get its Costco fix? The answer might surprise you.
The U.S. wholesale powerhouse is doubling down on its Australian expansion, strategically targeting new locations as budget-conscious shoppers increasingly embrace bulk buying. With two new warehouses slated to open next year in Victoria and Western Australia, Costco is also setting its sights on prime spots in Sydney, Perth, Adelaide, and—drumroll, please—Tasmania and Geelong. And this is the part most people miss: Costco’s move into Tasmania isn’t just a business decision; it’s a bold statement that challenges the notion that smaller markets can’t sustain big-box retailers.
Driving this rapid growth is Costco’s impressive financial performance. Retail expert Gary Mortimer highlights the company’s staggering profit of half a billion dollars after tax last financial year, outpacing Aldi’s $499.2 million. This success fuels Costco’s “long game” strategy to capture a larger slice of Australia’s grocery market. Mortimer explains, “Costco is a large-format business requiring significant space and land, but with population growth in areas like southeast Queensland, they’re also eyeing sites on the Gold Coast and Sunshine Coast.”
For many Australians, Costco’s appeal is undeniable. Take Susan, a pensioner from North Lakes, who shared with Seven News, “Being on a pension, I come here every one to three months to stock up. It’s cheaper, and the savings add up.” Her experience resonates with countless others who find Costco’s membership fee—ranging from $65 to $130 annually—easily offset by savings, especially on fuel at their discounted service stations.
Tasmania’s inclusion in Costco’s expansion plans has raised eyebrows. The state has long craved the arrival of retail giants like Aldi and Costco, known for their competitive pricing. Yet, both companies have historically shunned the island, leaving locals puzzled. Ray White Group’s Vanessa Rader previously attributed this to population size and scale, suggesting the market might not support a Costco or its distribution needs. But is this perception outdated? Costco’s current strategy suggests they’re ready to overcome these challenges, sparking debate about whether smaller markets are finally viable for big retailers.
The Greens have even proposed a $30 million plan to lure discount supermarkets to Tasmania, underscoring the political and economic push for more affordable shopping options. Meanwhile, Costco’s expansion is already taking shape with major projects underway. In Melbourne’s southeast, a $74 million warehouse and mega fuel station is planned for Pakenham, opening in 2027. Western Australia will welcome its third Costco in Alkimos in 2027, anchoring the $33 million Alkimos Central’s Home X Trade Hub.
These developments aren’t just about retail—they’re about job creation and economic growth. Each new store hires between 250 and 300 staff, with additional jobs during construction. Yet, not all expansions have been smooth sailing. A proposed Costco in Officer, Melbourne, faced a setback when the State Government rejected a council request, though the retailer remains committed to its growth plans.
Costco’s site selection is meticulous. They target locations with easy access to major roads, in growth areas or regions with populations of 400,000 to 500,000. Each warehouse requires approximately 14,000 square meters of space and 800 car parks, serving a trade area within a 45-minute drive. With just 15 stores in Australia compared to Aldi’s 600+, Costco sees immense potential, particularly in Sydney, where only three stores currently serve six million residents.
Here’s a thought-provoking question: As Costco expands, will it redefine the retail landscape in Australia, or will it face pushback from smaller markets and local businesses? Share your thoughts in the comments. One thing’s for sure—Costco’s aggressive push promises to intensify competition, offering Australians more access to bulk buying and discounted goods, a welcome relief in today’s challenging economic climate.
