In the 1970s, the leader of the Australian Council of Trade Unions (ACTU) and future Prime Minister of Australia, Robert J. "Bob" Hawke, was an informer of the United States of America. Using diplomatic cables from official archives, this article shows that Hawke gifted information about the Australian government, the Australian Labor Party and the labour movement, assisting the intelligence gathering efforts of the foreign power. In turn, the relationship influenced the development of Australian policy, including the abandonment of Keynesian economics and embrace of neoliberalism. His discreet relationshipdiscussed in detail for the first timewas not unusual among elites in the post-war period. However, Hawke was especially entrenched in the practise. This article will also show, through historiography and memoir, that the act of informing by elites began in the 1940s, as the United States was becoming Australia's key strategic ally.
