Bushranging began soon after British settlement with the establishment of New South Wales as a penal colony in 1788. The majority of early bushrangers were convicts who had escaped prison, or from the properties of landowners to whom they had been assigned as servants. These bushrangers, also known as "bolters", preferred the hazards of wild, unexplored bushland surrounding Sydney to the deprivation and brutality of convict life. The first notable bushranger, African convict John Caesar, robbed settlers for food, and had a brief, tempestuous alliance with Aboriginal resistance fighters during Pemulwuy's War. While other bushrangers would go on to fight alongside Indigenous Australians in frontier conflicts with the colonial authorities, the Government tried to bring an end to any such collaboration by rewarding Aborigines for returning convicts to custody. Aboriginal trackers would play a significant role in the hunt for bushrangers.
