Note on Australian languages with no known speakers: For some languages, we haven't been able to confirm speaker numbers. In other cases, there isn't anyone who has grown up speaking the language, but there are still people who identify with the language, and who are working to revitalize their languages. We've chosen to include these languages in the Catalogue for this reason.
