This paper describes a Nyungar language revitalisation project in the southern region of Western Australia conducted in partnership between a university research team and the Esperance Tjaltjraak Native Title Aboriginal Corporation. It discusses how linguistic analysis of historical Nyungar documentation was essential to addressing community aims of re-embedding the language into the community, developing and using pedagogical resources, and exploring new domains for language use. In particular, this paper focuses on the community's desire for the reclamation of a dialectal flavour of Nyungar that is distinctive to the Esperance region, and the factors contributing to a successful partnership between the researchers and the community organisation in terms of capacity-building, leadership, and sustainability.
