In Part 1, we learn how 50 years ago secret atomic tests were carried out on Australian soil in north–western South Australia. The traditional Aboriginal communities of the region were to be moved for their own safety but somehow they were covered in radioactive fallout. Some of the local Anangu people suffered radiation poisoning and died and many are still enduring the effects of that toxic exposure today. In Part 2, we discover 25 years ago the Anangu People of South Australia were allowed to return to part of their traditional lands affected by atomic bomb testing in the 50s and 60s. After what was called a nuclear waste cleanup they moved back to the settlement of Oak Valley in the Spinifex country of their forefathers.
