The Australian Competition and Consumer Commission blocked the opening of a proposed Coles supermarket in West Kalgoorlie on Wednesday [1].
The decision marks a significant application of the regulator's expanded authority to prevent market dominance. By stopping the expansion of a major corporate chain, the ACCC aims to protect the viability of smaller local businesses from being squeezed out of the market.
An ACCC spokesperson said the agency exercised its new competition powers to block the store because it would likely reduce competition in the area [1]. The regulator said that allowing the chain to expand further into the region could knock out smaller competitors and diminish the diversity of grocery options for residents [1, 2].
West Kalgoorlie currently has six supermarkets [2]. The proposed Coles store would have been the seventh supermarket in the town [1].
A reporter for MSN Money said that the corporate watchdog ruled a second Coles store would undermine local competition in the mining town [2]. The ACCC's intervention suggests a stricter approach to how national retailers scale their presence in regional hubs, where the impact on small businesses is often more acute than in metropolitan centers.
This move comes as the ACCC continues to test the boundaries of its newly granted powers to ensure that the retail landscape remains competitive. The agency said that its priority is maintaining a balance between corporate growth and the survival of independent operators [1].

This decision signals a shift in the ACCC's regulatory strategy, moving from a reactive posture to a proactive one. By blocking a store before it opens, the regulator is demonstrating that it will prioritize the preservation of existing small-scale competition over the expansion of major retail chains, potentially setting a precedent for other regional towns across Australia.
