Reverend Dr John Fraser (1834 – 1904) was an Australian ethnologist, linguist, school headmaster and author of many scholarly works. He is known for his revised and expanded version of Lancelot Threlkeld's 1834 work, An Australian Grammar, with the new title An Australian language as spoken by the Awabakal, the people of Awaba or Lake Macquarie (near Newcastle, New South Wales) being an account of their language, traditions and customs / by L.E. Threlkeld; re-arranged, condensed and edited with an appendix by John Fraser (1892). In this, Fraser created new divisions and terminology for some Aboriginal groups in New South Wales.
