First taken up by John Frazer from
Victoria in 1875 the station was initially known as
Cardilla. Frazer let the property go in 1878 and a
ballot was held, the lease going to Edgar Chapman, who sold off in 1883 to Peter Waite of the Beltana Pastoral Company. The property was stocked with just over 10,000 sheep, nearly 600 cattle and about 30 horses. In 1903 the property was amalgamated with two other stations, Cadelga and Haddon Downs, and had a flock of around 85,000 by 1905. The homestead was abandoned for a few years during the 1930s. A
plague of rats swept across the property from further north in Queensland in 1940, they were prevented from making it further south by the flooded
Cooper Creek. Cattle replaced sheep on the station in 1942 when the manager, Mr Napier, decided that the
wild dogs that were prevalent in the area and were inside the boundary fence at the time would cause less damage. The entire area was struck by
drought in 1946 with many cattle dying and properties destocking. Airmail delivery to remote properties in
outback South Australia, New South Wales and Queensland commenced in 1949. Cordillo Downs along with other remote properties including Mungerannie,
Clifton Hills,
Glengyle,
Davenport Downs,
Morney Plains, Mount Leonard,
Durrie,
Mulka, Tanbar,
Durham Downs,
Nappa Merrie, Lake Pure and
Naryilco were also on the route. The
Cooper Creek broke its banks in 1950 resulting in widespread flooding through the area. A
meteor was thought to have landed somewhere at Cordillo in 1954. The bright flash and ball of fire that lasted for several minutes was spotted from many properties including
Innamincka,
Muloorina and Narilya, all of whom reported the phenomena to the
Royal Flying Doctor Service. Beltana owned the property until 1981 when they sold it to Brookman Holdings for $1.2 million. Brookman holdings is owned by the Brook family, Bill Brook was 81 years old when he bought Cordillo, where he was employed in 1918 as a
ringer for 30
shillings per week. The property was owned by Anthony and Janet Brook in 2012, both of whom met
Prince Charles and
Camilla in
Longreach during their 2012 tour of the outback. The Brooks run a herd of approximately 40,000
Hereford cattle and are certified
organic producers of beef using the OBE Beef label. Both the historic main
Cordillo Downs Homestead and Woolshed and the
Cadelga Homestead Ruins are listed on the
South Australian Heritage Register. The woolshed was damaged by a storm in 2017, and restored with the help of Scottish stonemasons, with the work completed in July 2019. The stonework was restored using the traditional techniques, and the roof that had been blown off was replaced. ==Geography, vegetation and geology==
