https://en.wikipedia.org/wiki/Nuclear_weapons_tests_in_AustraliaThe United Kingdom conducted
12 major nuclear weapons tests in Australia between 1952 and 1957. These explosions occurred at the Montebello Islands, Emu Field and Maralinga.
Emu FieldThe atomic tests at Emu Field in 1953 were known as Operation Totem. The test site of Emu Field was abandoned just hours after the
second and final test, Totem 2.
MaralingaMain article: British nuclear tests at Maralinga
A testing site at Maralinga was established in 1955, close to a siding along the Trans-Australian Railway. Because supplies could be brought to the site via rail, it was preferred over Emu Field.
A total of seven major tests were conducted at Maralinga. Both the Federal government and Australian newspapers at the time were very supportive of the tests.[6] In 1952, the Liberal Government passed legislation, the Defence (Special Undertakings) Act 1952, which allowed the British Government access to remote parts of Australia to undertake atmospheric nuclear weapons tests. The general public were largely unaware of the risks from the testing program, stemming from official secrecy about the testing program and the remote locations of the test sites.
Before the tests could begin the Maralinga Tjarutja, the traditional Aboriginal owners of the land, were forcibly removed.[7]
An air base at Woomera, 570 km away, which had been used for rocket testing, was initially used as a base from which planes were flown for testing of the bomb clouds.
