Following European settlement in Australia, introduced diseases had a devastating impact on Aboriginal populations, ultimately claiming more lives than direct armed conflict. These diseases, to which Indigenous people had no prior immunity, caused such rapid population decline in areas like southeast Australia that many Europeans mistakenly believed Aboriginal peoples would soon become extinct.1

The introduction of these illnesses was compounded by the broader effects of colonization, including massive physical displacement, the loss of access to traditional lands, and the resulting inability to sustain traditional hunting and gathering practices. This forced disruption of life led to widespread poverty and alienation. In some regions, such as Tasmania, the combination of disease, violent conflict, and forced relocation nearly wiped out the entire Indigenous population.213

While humanitarian concerns eventually led to the establishment of reserves, these policies often resulted in further restriction and control rather than protection, leaving Aboriginal people marginalized within the developing colonies.21
