The Australian federal government is set to impose new obligations on major supermarket chains, including Coles, Woolworths, Aldi, and IGA, to treat their suppliers fairly. This move is part of a broader effort to crack down on anti-competitive behavior and address the rising cost of living. The new mandatory grocery code of conduct will be enforced with hefty fines, potentially reaching billions of dollars for breaches. Treasurer Jim Chalmers has revealed that fines could be as high as $10 million, with the new regulations aimed at ensuring fair treatment of suppliers and preventing price gouging. Labor commits to reforms, and multimillion dollar fines are expected. Notably, other retail heavyweights such as Bunnings and Chemist Warehouse will not be covered by the new code.
