The real numbers
Real talk: history books have been lowkey underselling the scale of Australia’s Indigenous population before 1788. A major new study published in Nature Human Behaviour suggests that about 2.22 million Indigenous people lived on the continent before the First Fleet arrived. That is up to seven times higher than some of the old-school estimates that have been floating around for decades.
The demographic crash
It’s giving a total tragedy. Researchers found that within just 73 years of European arrival, approximately 93% of the Indigenous population was lost. We are talking about 2.06 million excess deaths between 1788 and 1861 due to disease, frontier violence, and systemic oppression. By 1861, the population had plummeted to just 7% of its original size.
How they know
Scientists didn’t just guess. The team—which included Indigenous partners—used a mix of advanced computer modeling, genetic data, archaeological findings, and ethnographic records. They essentially mapped out how many people the land could actually support. This approach allowed them to move past outdated calculations from the 1930s that clearly missed the mark on the true impact of colonization.
The path forward
While the Indigenous population has been growing since the 1950s, it still hasn't hit those pre-colonial numbers. If current trends keep up, the experts project we might not see those levels again until 2047. As Distinguished Professor Larissa Behrendt AO put it, this isn't a minor detail; it’s a demographic catastrophe at the heart of the Australian story. But even with that, the resilience of Indigenous Australians remains absolutely next-level.
Why it matters
This research is essential for truth-telling and reconciliation. Understanding the true scale of this collapse helps us better grasp the reality of intergenerational trauma and systemic disadvantage today, and it reminds us that history is often biased by whoever is doing the writing.
