This paper discusses Language Maintenance and Revitalisation as Linguistic Justice with two community-initiated and -led Language Documentation Projects on the Indigenous Sign Language and Creole language used in the Miriwoong community in Kununurra, Western Australia. The paper explores how the ‘Two-Way’ collaboration is important in shaping the process and outcomes of Language Documentation (here Maintenance and Revitalisation). We argue that ‘Ground-up’ and community-led research is vital to the successful implementation of Language Maintenance and Revitalisation in which Indigenous Methodologies (Yarning, Storytelling, among others) together with methods of Western Sciences are applied. Depending on the needs of the community Language Documentation (as Language Maintenance, Revitalisation or Reclamation) is a way to achieve Linguistic Justice.
