Ngunnawal was the southern dialect of the Aboriginal Wallabalooa language of south-east Australia spoken in the now Yass District. The speakers possibly referred to themselves as the Ngunwal people, while European settlers called them the Yass Blacks. To better pursue native title claims, in 1996 with the active support of the Australian Capital Territory Government many Aboriginals living in the Territory came together to form the "New Tribe" of Ngunnawal people. However with the failure of the claims, the grouping split up and the Ngunnawal people are once again those referred to by early settlers as the Yass Blacks. With the growth of Canberra some Ngunnawal people now live in the territory of their traditional enemies, the Nyamudy people.
