Australia's biggest private landholding, which includes the world's largest cattle station, is up for sale by S. Kidman and Co.

Eleven cattle stations covering more than 100,000 square kilometres are being offered, including all stock and equipment.

S. Kidman and Co. is a majority family owned business, with 98 per cent of the shares in the unlisted public company owned by members of the Kidman family.

The company was founded by Sir Sidney Kidman in 1899 and has been in the hands of family members for over 100 years. The family shareholders are Australia's largest private landholders.

The business now includes a cattle feedlot and cattle stations across Western Australia, the Northern Territory, Queensland and South Australia.

Anna Creek Station in South Australia's outback is the largest at 23,000 square kilometres.

Other holdings include Durham Downs, Durrie, Glengyle, Morney Plains, Naryilco and Rockybank in Queensland; Innamincka, Macumba and Tungali in South Australia; Helen Springs in the Northern Territory and Ruby Plains in Western Australia.

"This is a world class asset of international significance," said Alex Thamm a rural valuer with Colliers International.

"With cattle prices, our trade agreements with Asia and the low Australian dollar, it is a very good time to be selling the Kidman business.

"An offer of assets of this calibre are not common."

Alex Thamm said the business has been built up over multiple generations, a fact that will appeal to buyers.

"To offer this property, walk-in walk-out inclusive of the cattle, plant and equipment, and the business generally, is a good move in the market place."

Managing director of S. Kidman and Co. Greg Campbell said family members had decided to sell to capitalise on current demand for quality Australian agricultural assets.

The company, which has its headquarters in Adelaide, employs 170 staff and the business turns off an average 15,000 tonnes of carcase beef each year, supplying 1.3 per cent of Australia's boxed beef exports.

The 11 properties currently have 155,000 branded cattle with 30,000 more calves to be marked this year.

The sale is being handled by Ernst and Young Adelaide, and further details will not be released before May.
