Artificial intelligence, productivity, Bunnings, Kmart and the future of Australia's economy: Sean Aylmer has a wide-ranging conversation with Wesfarmers CEO Rob Scott following the conglomerate's investor day.

Scott explains how AI is being rolled out across businesses including Bunnings and Kmart, why Bunnings still has significant room to grow beyond hardware, and how the Anko brand is expanding into new markets and new retail formats.

He also discusses the challenge of rising costs, the importance of productivity, opportunities in healthcare and international expansion, and the policy settings he believes could determine Australia's future competitiveness.
