Tribe is not really a meaningful or useful word in the Australian context Clan is not applicable to many Australian groups either As a linguist I prefer to talk about language groups as this is in many cases the highest level of group affiliation altho people from different language groups can have ceremonial and other ties Someone Ezeu moved yamaji to the list of tribes but I m going to remove it Yamaji is the word for man human being in Wajarri and is also one of the words used for that meaning in Badimaya As such it like ngayarda in the Pilbara and Koori in south east Australia is used to refer to Aboriginal people from a particular region the Murchison Gascoyne region of WA but may also be used to refer to Aboriginal people from any part of Australia It s not a tribe in any sense that I can determine
