An Australian Grammar

An Australian grammar : comprehending the principles and natural rules of the language, as spoken by the Aborigines in the vicinity of Hunter's River, Lake Macquarie, &c. New South Wales is a book written by Lancelot Edward Threlkeld and published in Sydney in 1834. It is a grammar of the Awabakal language.

In 1892 a revised and much expanded version was published by ethnologist John Fraser, as An Australian Language as Spoken by the Awabakal..., in which he and other contributors added much text, several appendices, and a map of the tribes of New South Wales as frontispiece.
