Nuclear weapons tests in Australia

The 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.

Several books have been written about nuclear weapons testing in Australia. These include Britain, Australia and the Bomb, Maralinga: Australia's Nuclear Waste Cover-up and My Australian Story: Atomic Testing: The Diary of Anthony Brown, Woomera, 1953. In 2006 Wakefield Press published Beyond belief: the British bomb tests: Australia's veterans speak out by Roger Cross and veteran and whistleblower, Avon Hudson.

The British conducted testing in the Pacific Ocean at Malden Island and Kiritimati known at the time as Christmas Island (not to be confused with Christmas Island in the Indian Ocean) between 1957 and 1958. These were airbursts mostly occurring over water or suspended a few hundred metres above the ground by balloon.

In Australia there were three sites. Testing was carried out between 1952 and 1957 and was mostly done at the surface. A few hundred smaller scale tests were conducted at both Emu Creek and Maralinga between 1953 and 1963.

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 Creek. 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. 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.
