Language:

Australian Aboriginal languages are a heterogeneous group of families of languages and isolated native languages of Australia and adjacent islands, although initially excluding Tasmania. The relationships between these languages is not currently clear, although substantial progress has been made in recent decades.

The Aboriginal Tasmanians were exterminated very early in the colonization of Australia and languages became extinct before they could be documented. Historically the inhabitants of the island were isolated from the mainland by the end of the ice age and apparently went no contact for over 10,000 years. Their language is unclassifiable with the limited data available, although it seems that there were similarities with the languages of the continent.
