[5] Prior to the arrival of the First Fleet in 1788, Prospect was inhabited by different groups of the Darug people including the Warmuli.

As European settlement expanded, the aboriginal people's ability to pursue their traditional lifestyle, which was already severely limited, disappeared.

Prospect Hill had been the frontier, which was the first, and perhaps only, area where large scale organised resistance by aboriginal people took place.

Hostility grew until by 1797, where a state of guerrilla warfare existed between indigenous people and the settler communities at Prospect and Parramatta.

The aboriginal people were led by their leader, Pemulwuy, a member of the Bidjigal tribe who occupied the land.
