The Toxic Legacy of Britain’s Nuclear Testing in Australia

The era of British nuclear testing in Australia was exrraordinary, and its secrets are still being uncovered. Because of ongoing British secrecy, we may not discover them all. In her talk Professor Tynan will examine the complex circumstances taht led the British first to Monte Bello Islands off the coast of Western Australia, then Emu Field and Maralinga in South Australia, to test their atomic weapons. The decision to do so followed the United States’ exclusion of Britain from nuclear weapons and energy R&D after World War II, ostensibly because of the detection of Manhattan Project spies. Australia acquiesced to the atomic tests without asking hard questions, and as a result considerable damage and suffering was inflicted, particularly on Indigenous people and service personnel.

Those hard questions only came decades later, and there are still many to be asked. The British conducted their testing with a greater emphasis on speed than safety. The recklessness of some of the tests carried out in Australia is stunning. Tynan will share specific stories of these dangerous tests and their deadly ramifications for Australians. She will also cover what happened after the British terminated the test series and deliberately misinformed the Australian government about the extent of contamination they left behind. All three test sites were abandoned without proper remediation. The aftermath led to a judicial enquiry, known in Australia as a Royal Commission, in the mid-1980s. This enquiry makred a major shift in Australian attitudes to the tests, and was an important mileestone in an era of uncovering and truth-telling that continues.

Professor Elizabeth Tynan is Head of the Professional Development Program at James Cook University’s Graduate Research School, where she teaches academic writing, editing, and critical thinking skills to postgraduate researchers. She is a former science journalist in both print and broadcast media. Her PhD from the Australian National University examined aspects of the British nuclear tests in Australia in the 1950s and 1960s.
