Australia’s richest person, Gina Rinehart, says farmers and the agriculture sector cannot afford the transition to net zero and governments should step in to cover most of the costs.

Speaking at a bush summit in Western Australia sponsored by her company, Hancock Prospecting, Mrs Rinehart also took aim at the media for its coverage of her recent court battle with her family, saying she had a “very close” relationship with her father Lang Hancock before he died in 1992.
