For tens of thousands of years, the Aṉangu people lived on the warm, red earth of their country.
The land provided them with food, water and shelter as they travelled around an area we now know as outback Far North South Australia.
But after colonisation, they were moved off their land: forcibly removed, sent into missions across the region and displaced by train lines linking Australia's east and west that impacted their water supply.

In 1984, the South Australian government handed much of the land back to its traditional owners. But by this point, parts of it were uninhabitable because of British nuclear testing.
In August 1945, the United States dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki, bringing a swift end to World War II and beginning the nuclear arms race of the US, Soviets and their allies.
To the British, the vast (and in their minds, uninhabited) lands around Maralinga in South Australia seemed like an ideal spot for nuclear testing, and the Australia Government agreed to "help the Motherland".
In the 1950s and 60s, Maralinga was a testing site for seven atomic bombs, including one twice the size of the bomb dropped on Hiroshima. There were also "minor trials", where officials deliberately set fire or blew up plutonium with TNT, just to see what would happen. These scattered long-lived plutonium over a large area at Maralinga.
