text: The Kidman cattle empire is Australia's largest landholding, encompassing some of the driest and toughest country Australia has to offer.
  Its story begins in the 1890s with Sir Sidney Kidman and his elder brother Sackville, who embarked on an ambitious venture that would transform agriculture in Australia.
  The two brothers wanted to grow livestock in the country's dry centre, supported by Queensland's channel country rivers - the Georgina, the Diamantina and Cooper Creek.
  The plan was that tropical rain from the north would deliver water needed for farming to flourish in this harsh environment.
  The Kidmans' ambition, wrote biographer Jill Bowman, was to establish "a chain of stations that were almost drought-proof, places that when linked together would provide a substantial water supply".
  Sackville Kidman died in 1899, but Sidney turned their dream into reality, founding the company S. Kidman & Co the same year.
  Today the business encompasses 19 properties across the Northern Territory, South Australia, Queensland and Western Australia.
  It owns 101,411 sq km (39,155 sq miles) of land in total - that's more than 1% of Australia's land mass and larger than Ireland. One of its properties is Anna Creek, the world's biggest cattle station, which stretches across 23,677 sq km.
  The Kidman family has owned and managed the business for 116 years. But in April this year it was put on sale for a projected sum of A$325m ($232m; Â£152.3m).
  On Thursday however Australia's government decided to block the sale to foreign investors.
  Selling so much of Australia's outback to foreigners would be against the national interest, Treasurer Scott Morrison said.
  His reasoning? Part of property is inside the Woomera Prohibited Area (WPA), a military weapons testing range in South Australia.
  The country's prime minister, Malcolm Turnbull, said the sale was blocked on national interest grounds and there was no discrimination against any particular buyer.
  About Sir Sidney Kidman
  Kidman & Co's business focus has long been on growing grass-fed beef for domestic and international markets.
  Headquartered in Adelaide, the firm says it supplies about 15,000 tonnes of beef carcass every year to markets around the world.
  It is not clear if prospective buyers would maintain this focus, but there's no argument they would enter Australia's agricultural scene at a pivotal time.
  As the mining boom subsides and the country looks elsewhere for economic growth, the business of farming the country's vast land for meat and other agricultural commodities has never been more important.
  Mr Morrison indicated that the government may be willing to see Kidman broken for sale. So foreign investors may yet possess at least some of its vast cattle empire.
  Simon Talbot, head of the National Farmers Federation, told the BBC that opening up agricultural growth in northern Australian areas couldn't be done without foreign investment.
  Even where large agricultural properties were foreign owned, the produce grown on them needed be transported using Australian infrastructure and jobs would be generated for Australian workers, he explained.
  "People are starting to realise that as the mining boom is over, agriculture could become the next pillar of the Australian economy - but unfortunately we're not going to get there without significant investment," he said.
