Are Dogs Allowed in Costco Australia?

Why Dogs Aren't Allowed in Costco

Even though Costco looks different from a traditional supermarket — with its warehouse layout, wide aisles, and vast range of non-food products — it is classified as a food retail environment under Australian law. This means it is subject to the same food safety regulations as supermarkets, which prohibit animals in areas where food is handled, stored, or sold.

The restriction is not a Costco-specific preference; it is a legal requirement. Costco's policy applies consistently across all warehouse locations in Australia, and there are no exceptions for small dogs, dogs in bags or carriers, or emotional support animals. The only animals permitted are legally recognised assistance animals under the Disability Discrimination Act 1992.

What to Do When You Want to Bring Your Dog Along

Costco trips tend to be long, which makes leaving your dog in a hot car a bad option. A better approach is to plan a stop nearby where your dog can wait comfortably with another person, or to take advantage of Costco's online delivery service — available to members — which means your dog doesn't need to be factored into the errand at all. Some Costco locations in Australia are situated near outdoor areas, cafés, or parks where dogs are welcome while you shop.

Does the Policy Vary Between Costco Locations in Australia?

No. Costco's no-pet policy is applied consistently across all Australian warehouse locations — Sydney, Melbourne, Brisbane, Adelaide, Canberra, and beyond. It is not left to the discretion of individual store managers. Unlike some retailers where the policy can vary between sites, Costco operates a uniform policy across the country. This is partly due to the fact that it is a membership club with consistent operating standards, and partly because the food retail classification makes the no-pets rule a legal requirement rather than a choice.

Assistance Animals at Costco

If you rely on an assistance animal, you have the legal right to bring them into any Costco warehouse in Australia. Costco is required to comply with the Disability Discrimination Act 1992, which gives people with disabilities the right to be accompanied by their assistance animal in any premises open to the public. Costco staff may ask two questions — whether the animal is an assistance animal, and what task it is trained to perform — but cannot ask for certification or refuse entry on that basis alone.

Costco's Outdoor Areas and Your Dog

Costco's outdoor areas — including carparks and any external seating near the food court — are generally accessible to dogs, as they are not part of the food-handling premises covered by the no-pets rule. If you're shopping as a pair, one person can wait outside with your dog while the other shops, which is a practical solution for Costco's longer-than-average shopping trips.

Frequently Asked Questions

Can I bring my dog into Costco Australia?

No. Dogs are not permitted inside Costco warehouses in Australia. Costco sells food in large quantities, which means it is classified as a food retail environment and subject to Australian food safety laws that prohibit animals from areas where food is sold or stored. This applies regardless of your dog's size or breed, and whether they are carried or walked.

Are assistance dogs allowed in Costco?

Yes. Assistance animals are legally permitted in all Costco warehouses in Australia under the Disability Discrimination Act 1992. Costco staff cannot refuse entry to a customer accompanied by a legitimate assistance animal. You are not required to show documentation, though staff may ask whether the animal is an assistance animal and what task it performs.

Does Costco have an official dog policy?

Costco's approach aligns with Australian food safety legislation, which effectively sets the policy. Globally, Costco states that service animals are welcomed in compliance with relevant disability legislation. No pet dogs are permitted under any circumstances — including small dogs in bags or trolleys — as this creates hygiene issues in a food retail environment.

Can I leave my dog in the car while I shop at Costco?

No — leaving a dog in a parked car, particularly in warm Australian weather, is dangerous and illegal under animal welfare laws in most states and territories. Even with windows cracked, temperatures inside a parked car can reach dangerous levels within minutes. If you need to do a Costco run, arrange for someone to stay with your dog nearby, or use Costco's online delivery service so your dog doesn't need to factor into the trip at all.

Does it matter that Costco sells pet food and pet products?

No. Costco stocks a range of pet food, treats, and accessories — but selling pet products does not change the store's classification as a food retail environment. The no-pets rule exists because of how food safety law treats the physical premises, not because of what products are sold there.

Is Costco's dog policy the same everywhere in Australia?

Yes. The no-pet policy is consistent across all Costco warehouse locations in Australia, including Sydney (Marsden Park, Auburn, and Crossroads), Melbourne (Ringwood and Moorabbin), Brisbane (North Lakes), Adelaide (Kilburn), and Canberra. There is no state-by-state variation — the policy reflects both Costco's global operating standards and Australian food safety legislation.

Which large retailers in Australia do allow dogs?

Bunnings is Australia's most well-known dog-friendly major retailer, officially welcoming dogs on a lead across all stores. Petbarn also welcomes dogs in-store, which is fitting for a pet supplies retailer. Beyond those two, most large-format retailers — including supermarkets, department stores, electronics chains, and membership warehouses like Costco — do not allow dogs inside.
