Australian retailer Coles is investing in technology in a bid to save the company $1 billion in costs over the next four years. Coles chief executive told the Sydney Morning Herald that the savings were needed to combat the rising cost of wages, energy and an increasingly competitive environment. The company said that it would instead invest in warehouse and stockroom automation, upgraded anti-theft systems, labour planning tools, and self-service checkouts.

Last week Coles announced that it would be cutting 450 roles at its head office in Melbourne.
