Королевская комиссия МакКлелланда по британским ядерным испытаниям в Австралии.

The McClelland Royal Commission or Royal Commission into British nuclear tests in Australia was an inquiry by the Australian government in 1984–1985 to investigate the conduct of the British in its use, with the then Australian government's permission, of Australian territory and soldiers for testing nuclear weapons. It was chaired by Jim McClelland.

In September 1950, the then UK Prime Minister, Clement Attlee, requested via a secure telegraph, to Australia's Prime Minister Sir Robert Menzies, to conduct a series of atomic tests at the Monte Bello Islands off the coast of Western Australia. Over the next thirteen years, twelve major British nuclear tests would occur on Australian territory, along with thirty "minor" atomic trials testing sub systems. The last Vixen B trial occurred in 1963 whereupon the United Kingdom moved its testing operations to the United States. The Royal Commission into nuclear tests arose out of a public outcry, led by media reports, over the increasing evidence (and statistical significance) of premature deaths of former Australian staff associated with the atomic tests and subsequent birth defects of their off springs. Likewise, remote indigenous communities downwind of the tests had statistically significant higher rates of radiation related diseases not generally found among indigenous communities to the same level. In light of the increasing evidence and public lobbying by concerned groups, the Hawke Labor Government established a Royal Commission to investigate the British atomic tests in Australia.

The Royal Commission was told that 30 badly leaking drums of radioactive waste were dumped off the West Australian coast. The Commission was also told that acting Prime Minister Arthur Fadden had sent a message to the British PM asking "What the bloody hell is going on, the cloud is drifting over the mainland?". A CSIRO scientist is making use of the thin blanket of radioactive caesium 137 laid over Australia from atmospheric nuclear tests to measure soil erosion. The McClelland Royal Commission was told that one hundred Aboriginal people walked barefoot over nuclear contaminated ground because boots they had been given didn't fit. The 1953 British nuclear test that allegedly caused 'black mist' phenomenon in South Australia should not have been fired and the fallout was about three times more than forecast, according to a scientist who was involved in the tests. A house built less than 200 metres from an area mined for mineral sands 25 years ago is still contaminated from mineral sands tailings which are dangerously radioactive. According to a special report on an investigation of residual radio active contamination, about 100,000 dangerous metal fragments contaminated with plutonium still litter the Maralinga atomic test range – 25 years after the atomic tests which caused them. A miner has told the McClelland Royal Commission on British nuclear weapons tests in Australia, that geiger counter readings of the fallout levels near Marble Bar were "off the scale".

The report's approach and conclusions apparently differed from the British Government's official history, based on official British records, by Lorna Arnold. This report emphasized the partnership between the two nations, and noted that the approach taken towards safety was to international standards of the time and had contrasted with the historic disregard of Australian authorities toward the welfare of indigenous people. Some observers have noted that both reports were framed in the politics of the time: Britain wished to minimize its responsibility, while the Australian government of Bob Hawke wished to implicate their political opponents alongside the British, and have suggested that the timeline of the inquiry was chosen so as not to implicate earlier Labor governments. However, the Australian Labor Party had not been in power federally from 1950 until 1972, clearly undermining that argument. Likewise the Arnold report was criticised for being authored by a former employee of the United Kingdom Atomic Energy Authority (UKAEA), and for the author having never visited the test sites nor interviewed Australian participants who worked on the atomic tests. The Royal Commission witness statements of recounting discussions between Australian RAAF and USAF B 29 flight crews clearly demonstrate that the tests were not at then international standards in terms of testing instruments nor health and safety precautions for radiation. The Royal Commission heard ample evidence of British scientists being fully dressed in protective radiation suits that were not issued to Australian staff working in the same high risk radiation zones. Overall the Arnold argument that the British nuclear tests were a partnership was not compatible with the documented facts that the British controlled and managed the tests and the Australians worked under direction from British atomic test leaders.

The Royal Commission formed part of the plot of the film Ground Zero (1987), starring Colin Friels and Jack Thompson.
