became more intense. Journalist Brian Toohey ran a series of stories in the Australian Financial Review in October 1978, based in part on a leaked Cabinet submission. In June 1993, New Scientist journalist Ian Anderson wrote an article titled "Britain's dirty deeds at Maralinga" and several related articles. In 2007, Maralinga: Australia's Nuclear Waste Cover-up by Alan Parkinson documented the unsuccessful clean-up at Maralinga. Popular songs about the Maralinga story have been written by Paul Kelly and Midnight Oil. Background During the early part of the Second World War, Britain had a nuclear weapons project, code-named Tube Alloys, which the 1943 Quebec Agreement merged with the American Manhattan Project to create a combined American, British, and Canadian project. The British Government expected that the United States would continue to share nuclear technology, which it regarded as a joint discovery, after the war, but the US Atomic Energy Act of 1946 (McMahon Act) ended technical co-operation. Fearing a resurgence of United States isolationism, and Britain losing its great power status, the British Government restarted its own development effort, under the cover name "High Explosive Research". In the 1950s Britain was still Australia's largest trading partner, although it was overtaken by Japan and the United States by the 1960s. Britain and Australia still had strong cultural ties, and Robert Menzies, the Prime Minister of Australia from 1949 to 1966, was strongly pro-British. Most Australians were of British descent, and Britain was still the largest source of immigrants to Australia, mainly because British ex-servicemen and their families qualified for free passage, and other British migrants received subsidised passage on ships from the UK to Australia. Australian and British troops fought together in the Korean War from 1950 to 1953 and the Malayan Emergency that went from 1948 to 1960. Australia still maintained close defence ties with Britain through the Australia New Zealand and Malaya (ANZAM) area, which was created in 1948. Australian war plans of this era continued to be integrated with those of Britain, and involved reinforcing British forces in the Middle East and Far East. The Australian Government had hopes of collaboration with Britain on both nuclear power and nuclear weapons, and was particularly interested in developing the former, as the country was then thought to have no oil and only limited supplies of coal. Plans for nuclear power were considered along with hydroelectricity as part of the post-war Snowy Mountains
