During the first 20 years of settlement, there was only limited contact between the settlers and Aboriginal people. Over the succeeding years, the Ngunnawal and other local indigenous people effectively ceased to exist as cohesive and independent communities adhering to their traditional ways of life. Those who had not succumbed to disease and other predations either dispersed to the local settlements or were relocated to more distant Aboriginal reserves set up by the New South Wales government in the latter part of the 19th century.
