British Nuclear Testing in Australia
Monte Bello Islands, Emu Field and Maralinga, Australia · 1952–1963
Between 1952 and 1963, the British government, with the agreement and support of the Australian government, conducted nuclear-weapons testing at the Monte Bello Islands, Emu Field and Maralinga. Australia's radiation-protection agency states that 12 major atomic detonations took place: three at Monte Bello, two at Emu Field and seven at Maralinga. In addition, numerous smaller trials investigated weapon components and safety; at Maralinga, some of these 'minor trials' dispersed plutonium and became the principal source of long-term contamination. The tests occurred in remote areas that officials treated as suitable for weapons work, but those landscapes were not empty: Aboriginal peoples, including Pitjantjatjara and Yankunytjatjara communities, had longstanding relationships with the land, and the National Archives of Australia states that their permission was not sought. Growing concern eventually led the Australian government to establish the McClelland Royal Commission in 1984. Its work examined safety, radiation exposure, contamination and the treatment of Aboriginal communities. Later remediation removed or contained contaminated material, but the testing program left a legacy of disputed health claims, cultural loss, environmental damage and institutional mistrust.
