I'm quite confused, because practically all the samples I looked at from
https://incubator.wikimedia.org/wiki/Category:Wp/nys are articles
in English, not in Nyungar. A new language edition of Wikipedia needs to be
in that language, not content in another language (in this case English)
about that language and its culture, etc. The content as it presently stands should either be incorporated into the English Wikipedia (although with their stringent notability criteria I'm afraid a lot, if not most it, would be deleted) or into a separate wiki.
