User:OosWesThoesBes, who is a sysop and active contributor on Incubator and Multilingual Wikisource, has been collaborating with User:Gnangarra of the Noongar project.  They make the following comment and suggestion:

The main issue here seems to lie in two things: 1. the desire to spread/record knowledge of the local culture; 2. the inability of many tribal people (no offense meant, I'm not from Australia, nor am I a native English speaker, so please do correct my terminology [I'd use "aboriginal"–SJW]) to speak or understand the Nyungar language fluently. A simple solution to this would be the creation of a separate namespace in which English translations are provided, while the pages themselves are written in Nyungar. This will keep the main namespace free of English, while the knowledge to the culture is still available to those interested, who are not able to understand or have difficulty understanding the language itself. This way, the Wikipedia can be used both to spread the knowledge of the Nyungar culture, as well as providing a base for a broad encyclopedia written in the Nyungar language about all subjects.
