The term can include both Tasmanian languages and the Western Torres Strait language, but the genetic relationship to the mainland Australian languages of the former is unknown, while that of the latter is Pama–Nyungan, though it shares features with the neighbouring Papuan, Eastern Trans-Fly languages, in particular Meriam Mir of the Torres Strait Islands, as well as the Papuan Tip Austronesian languages. Most Australian Aboriginal languages belong to the Pama–Nyungan family, while the remainder are classified as "non-Pama–Nyungan", which is a term of convenience that does not imply a genealogical relationship.
