Between late 1969 and mid-1972 there were 176 premeditated and politically motivated attacks against a range of mostly government, military, judicial, diplomatic and commercial targets in Australia. Most were undertaken by radical left-wing actors. Such incidents and the organisations and individuals who carried them out can be examined through the lens of ‘home-grown’ terrorism. This article corrects the popular and historiographical amnesia associated with these events and demonstrates that like the moderate social movements of the ‘long Sixties’ that sustained Australia's ‘Years of Hope’, the home-grown terrorist actors who contributed to Australia's ‘Days of Rage’ were, most especially, influenced by American developments, cultural productions and actors. Further, in its attempts to understand and deal with these new threats, elements of the Australian Security Intelligence Organisation (ASIO) were similarly influenced by a range of American ideas and events including social science research methodologies.
