New federal regulations targeting the Australian grocery sector are set to take effect on 1 July, introducing significant financial penalties for retailers found to be overcharging consumers. The legislation, which addresses ongoing concerns regarding pricing practices, specifically targets “very large” retailers that report annual turnovers exceeding A$30 billion (approximately US$20.7 billion).
Regulatory Scope and Financial Penalties
As of the current market structure, the new rules primarily impact the nation’s two largest supermarket chains, Coles and Woolworths. According to recent financial reports, Woolworths recorded group sales of A$69.1 billion for the 2025 financial year, while Coles reported A$44.3 billion. Both entities fall well above the threshold established by the federal government.
Under the new framework, the Australian Competition and Consumer Commission (ACCC) is tasked with enforcement. The penalties for violations are substantial, with the maximum fine determined by whichever of the following three metrics is the greatest:
- A fixed penalty of $10 million
- Three times the financial benefit gained from the violation
- 10% of the company’s annual turnover
Enforcement and Monitoring Strategy
The legislation does not define a rigid, universal threshold for what constitutes an “excessive” price. Instead, the ACCC will evaluate pricing information on a case-by-case basis, considering “relevant circumstances” such as the supply costs and what constitutes a reasonable margin for the retailer. To facilitate oversight, the regulator plans to monitor a select group of essential products.
“We will focus our attention on products where excessive pricing is likely to cause the most harm to consumers,” said Catriona Lowe, the acting chair of the ACCC. The agency intends to publish a list of these focus products in the coming months, utilizing data from supermarkets alongside reports from both consumers and suppliers to guide their investigations.
Broader Context of Retail Scrutiny
These new measures arrive during a period of heightened regulatory and legal scrutiny for Australia’s major supermarket chains. In May, a federal court ruled that Coles had made false or misleading representations regarding discounts in its “Down Down” promotion. Simultaneously, Woolworths is currently facing separate ACCC legal action concerning its “Prices Dropped” promotional campaigns.
The ACCC has indicated that it will provide regular updates on its compliance monitoring, signaling a shift toward more proactive intervention in the grocery retail market. While the industry adjusts to the new legal requirements, the focus remains on ensuring transparency in pricing and protecting consumer interests against potential market power abuses.
