Revised Pre-Colonial Population Estimates
The study, led by researchers including Associate Professor Alan Williams and Professor Corey Bradshaw, combined genetic reconstructions, archaeological findings, ethnographic observations, and computer models to reconstruct population history. The team calculated a median pre-colonial population of 2.22 million, corresponding to approximately 0.29 people per square kilometer.
This figure is substantially higher than earlier historical estimates, which generally ranged from 250,000 to 1 million people. A prominent earlier assessment by anthropologist Alfred Radcliffe-Brown in the 1930s placed the population at approximately 250,000. The new research suggests that previous figures were underestimates because they did not fully account for the devastating effects of deadly diseases, frontier violence, and structural violence that occurred before the earliest Australian censuses were conducted.
