Coles and Woolworths have significantly outperformed their competitors in terms of profitability, as evidenced by recent data. In 2008, the profits of Australia's grocery giants were comparable to those of supermarkets abroad. However, by 2024, they have risen to become some of the most profitable in the world. Sixteen years ago, the Rudd government initiated an inquiry into the supermarket industry due to growing public dissatisfaction with grocery prices. At that time, the market was already heavily concentrated, with Coles and Woolworths holding a combined 65% market share. The Franklins chain was struggling, and Aldi was just beginning its expansion in Australia. The landscape has since changed dramatically, with Coles and Woolworths solidifying their dominance in the grocery sector.
