Ocado’s white-label shopping technology will help grow Coles’ online grocery business to compete with the likes of Amazon. Two warehouses will be built by the end of 2023 in Sydney and Melbourne. Coles trades from more than 2500 sites, including 818 supermarkets, and made A$39.4 billion (£21.3 billion) in annual sales last year, over A$1bn (£500,000) of which came from online.
