Maralinga, in the remote western areas of South Australia, was the site, measuring about in area, of British nuclear tests in the mid-1950s. In January 1985 native title was granted to the Maralinga Tjarutja, a southern Pitjantjatjara Aboriginal Australian people, over some land, but around the same time, the McClelland Royal Commission identified significant residual nuclear contamination at some sites. Under an agreement between the governments of the United Kingdom and Australia, efforts were made to clean up the site before the Maralinga people resettled on the land in 1995. The main community, which includes a school, is Oak Valley. There are still concerns that some of the ground is still contaminated, despite two attempts at cleanup. History Nuclear tests and cleanup Maralinga was the scene of UK nuclear testing and was contaminated with radioactive waste in the 1950s and early 1960s. Maralinga was surveyed by Len Beadell in the early 1950s. It followed the survey of Emu Field, which was further north and where Operation Totem with two nuclear tests was conducted. On 27 September 1956, Operation Buffalo commenced at Maralinga, as Emu Field was found to be too remote a site. The operation consisted of the testing of four fission bombs. Two were set atop towers, one at ground level, and one released by a Royal Air Force Vickers Valiant bomber from a height of . This was the first launching of a British atomic weapon from an aircraft. Operation Antler followed in 1957. Antler was designed to test the triggering mechanisms of the weapons. Three tests began in September. The first two tests were conducted from towers; the last was suspended from balloons. Yields from the weapons were 1 kiloton, 6 kilotons and 25 kilotons respectively. Participants in the test programme were prohibited from disclosing details of its undertakings. Risking incarceration, nuclear veteran Avon Hudson became a whistle-blower and spoke out to the media in the 1970s. His disclosures helped pave the way towards a public inquiry into the tests and their legacy. The McClelland Royal Commission of 1984–1985 identified significant residual contamination at some sites. British and Australian servicemen were purposely exposed to fallout from the blasts, to study radiological effects. The local Aboriginal people have claimed they were poisoned by the tests and, in 1994, the Australian Government reached a compensation settlement with Maralinga Tjarutja of $13.5 million in settlement of all claims in relation
