Hi Brian.
If you can get hold of the book" Maralinga" by Judy Nunn read it. Pig Iron Bob our illustrious PM of the time didn't even ask his Cabinet if Britain could test atom bombs at Maralinga he just gave them the OK, the British secret service saw to it that Australians were kept in the dark. I believe that now the massive increase in child cancer is because of the winds that sweep the contaminated dust from that testing area, It also started to change the weather in Aus.
