Short Historical Context

Before British colonisation, Australia was home to around 750,000 Indigenous people belonging to more than 500 distinct groups and cultures that had existed for tens of thousands of years. The arrival of British settlers and convicts in 1788 brought massive disruption, including land dispossession, violence, and disease, which caused severe population decline among Indigenous communities.

From 1788 to 1901 , Britain established multiple colonies across the continent (New South Wales, Van Diemen’s Land/Tasmania, Western Australia, South Australia, Victoria, Queensland), gradually extending control over most Indigenous lands. In 1901 , these colonies federated to become the Commonwealth of Australia , ending the formal colonial period but not its ongoing impacts on Indigenous Australians.
