In late 2018, Australian farmers Viv Oldfield and Donny Costello teamed up to buy Clifton Hills, a 1.65 million-hectare cattle station in South Australia that is widely considered to be one of the world's largest farms.

Earlier this year, their joint venture Crown Point Pastoral boosted its holdings by a further 3.26 million hectares after it bought three stations from Gina Rinehart, bringing its total landmass to 7.2 million hectares. The families are now the largest private land owners in Australia.
