The name is derived from Awaba, which was the native name of the lake. Awabakal was studied by Reverend Lancelot Edward Threlkeld from 1825 until his death in 1859, assisted by Biraban, the tribal leader. His Specimens of a Dialect of the Aborigines of New South Wales in 1827 was the earliest attempt at exhibiting the structure of an Australian language.
