The South Western region includes Campbelltown, and encompasses the area south to Goulburn and north-west to Wallerawang. The most important living areas in the nineteenth century were in the Burragorang Valley, which contained more Aboriginal reserves and conditional purchases than in all the rest of Sydney. All but one had been revoked by the time the valley was inundated in 1956 to form the Burragorang Dam.
In the first half of the twentieth century the key living site was the Gully, Katoomba. Though never an official reserve, but tolerated until the 1950s by the Whites, the Gully stood at a junction of many of the Gundangara walking trails between the Hawkesbury and Burragorang Valley, and the western side of the Blue Mountains.
