Awkward for Albo re nuclear power, page-5

Yeah. Sure they did.

With the agreement of the Australian Government, Britain tested atomic weapons at three sites on Australian territory: the Montebello Islands off Western Australia, and Emu Field and Maralinga in South Australia.

The testing took place from 1952 to 1963, mostly at Maralinga.

Australian authorities did not discover the extent of the contamination at Maralinga until 1984, just before the land was to be returned to its Aboriginal owners.
