This report details an inquiry investigating the role of Australia's 'big box' retailers and large format retailers in price setting. For the purpose of the inquiry, a ‘big box’ retailer refers to a retail store that occupies a large physical footprint and offers a variety of products and a broad product mix to its customers.

The inquiry had particular reference to:

• the market behaviour of such retailers, including price negotiation practices, abuse of market power and engagement with suppliers
• whether big box and large format retailers that sell products that fall under the category of grocery should be included in the grocery code of conduct
• acquisition and use of land.

The committee received 19 submissions, which are available on the committee’s website, but was unable to hold public hearings prior to the 2025 Federal election being called. As a result, the committee has not fully considered and tested evidence provided to the inquiry, and is not in a position to make findings or recommendations.
