'Australia has a long history of epidemics. In 1983, Noel Butlin went so far as to argue that colonial Australia was constituted on the consequences of epidemic. Butlin was referring to smallpox, which had catastrophic consequences when encountered on the east coast by Indigenous Australians with limited or no herd immunity. This was ‘our original aggression’. Australia’s history prior to the twentieth century is punctuated by the introduction of diseases which took a heavy toll, especially on vulnerable segments of the population. Until the years after World War Two, infectious diseases were commonplace in a way that has generally been forgotten in the sanitised and healthy twenty-first century.' (Introduction)
