This paper interrogates representations of colonial authority, in particular the police force, in three films with a colonial Australian setting that were produced following the Second World War by British or Australian producers: the local production Captain Thunderbolt (1953) directed by Cecil Holmes; Jack Lee’s British adaptation of Australian literary classic Robbery Under Arms (1957) and Harry Watt’s Eureka Stockade (1949), which was the British production company Ealing Studios’ second production in Australia. I argue that the three films reflect differing approaches to understanding Australian national identity through their representations of authority, ideologically influenced by left-wing politics, the global marketplace and British imperialism. Where Captain Thunderbolt treats the colonial police and government with the sardonic irony and distance of a resistant community, both Eureka Stockade and Robbery Under Arms reinforce and justify Australia’s colonial administration. By detailing the economic, political and social contexts that contributed to these films, I demonstrate how various interest groups appropriated notions of Australian character and history to suit their ideological goals in line with Richard White’s (1992) arguments in ‘Inventing Australia’. Turning to history and folklore, these interests – including the Australian government, British media conglomerate the Rank Organisation and various left-wing organisations – infused the past they evoked in these films with new meanings that suited their vision of the future.
