Mitre 10 has accused rival Bunnings of using its market dominance to secure an exclusive hardware partnership with Uber Eats, prompting a formal complaint to the Australian Competition and Consumer Commission (ACCC).

The dispute centres on a new deal unveiled last week that will see more than 30,000 Bunnings products made available for on-demand delivery via Uber Eats, starting with 15 stores before expanding across Australia and New Zealand.

Mitre 10, owned by Metcash, claims the agreement effectively froze its own expansion on the platform.

The retailer had launched a trial with Uber Eats in October 2025 across 19 stores, offering around 8,000 items, and was in talks to extend the rollout.

According to Mitre 10 hardware boss Scott Marshall, Uber Eats informed the company in February that it would pause the trial and not onboard additional stores, citing a new exclusive arrangement with Bunnings.

“We believe that Bunnings has responded to the success of our partnership and used their scale and market dominance in hardware to keep Mitre 10 stores from accessing the platform,” Marshall said.

Mitre 10 said its agreement with Uber Eats was non-exclusive and did not seek to restrict other hardware retailers.

Wesfarmers-owned Bunnings rejected concerns, saying exclusivity agreements are common in retail and that strong competition benefits customers.

The company said the partnership provides shoppers with faster, more convenient access to DIY and garden products.

Uber Eats said existing Mitre 10 stores remain on the platform but declined to comment on the paused expansion.

The complaint adds to scrutiny of Bunnings’ market power following its appearance at the Senate supermarket inquiry.

Bunnings generates around $19 billion in annual sales, compared with Metcash’s $3.6 billion hardware division.
