The ‘Empty Land’ Myth: How Many Yugambeh People Were Really Here?

By Yugambeh Nation2 minute read

Most people are taught that before 1788, Aboriginal groups were small: perhaps a few groups of 150 people wandering here and there across a vast area. The data says otherwise. Read through the lens of science and statistics, the historical record shows a society far larger, denser and more complex than the history books suggest.

The survivor snapshot

In the 1860s, settlers recorded three local clans meeting with 600 people, about 200 per clan. In the 1850s, Gresty, a park ranger, estimated 2,500 people living across the Logan, Albert, Coomera, Nerang and Tweed river systems.

These were not starting numbers; they were survivor numbers. By 1850, Yugambeh Country had already endured 70 years of a biological catastrophe that moved faster than the frontier itself.

Working backwards

To have 2,500 people left in 1850 after decades of ‘ghost epidemics’, the original population had to be far larger. Inverse modelling works back through each stage of decline, from the most recent to the earliest:

  • 1840s to 1850s, the frontier war (about 40%). Direct colonial violence, and being pushed off traditional food sources, caused immediate spikes in mortality.
  • 1829 to 1831, the second smallpox wave (about 50%). A massive outbreak swept through eastern Australia. In ‘virgin soil’ populations, smallpox has a fatality rate of 50 to 90%.
  • 1790s to 1820s, the fertility gap (about 20%). Introduced diseases such as syphilis meant fewer babies were born, and fewer survived. The population was not only dying; it was being prevented from renewing.
  • 1789, the first great pox (about 50%). Smallpox hit Sydney in 1789 and travelled along Aboriginal trade routes to the Gold Coast decades before the first white settler arrived.

Estimated Yugambeh population, working backwards

  1. 1850sSurvivor baseline, recorded by Gresty2,500
  2. 1840sFrontier violence and displacement4,200
  3. 1829 to 1831Second smallpox wave8,400
  4. 1790s to 1820sThe fertility gap10,000+
  5. Before 1789Before the first great pox15,000+
Each bar adds back the losses of the stage after it, starting from the 1850s survivor count. Figures are the Nation’s estimates.

The reality: 9,000 to 15,000 people

When the numbers are worked backwards, the evidence is clear. The resource-rich Yugambeh river systems, some of the most fertile land on earth, did not support small groups of a few dozen people. They supported upwards of 15,000.

This is not the loss of a few bands of hunters. It is the collapse of a dense, thriving nation.

When we realise how many people were actually here, we realise the true scale of what was taken, and the incredible strength of the descendants who are still here today.
