James Charles Burnett (1815—1854) a.k.a. "John" was a surveyor and explorer in New South Wales (including Queensland), Australia. He was the head of the first Survey Office established at Brisbane in 1844.
Note, the separation of Queensland from New South Wales did not occur until 1859 and so the name Queensland was not used in Burnett's lifetime.
James Charles Burnett was born in North Britain (possibly Scotland), the son of William Burnett. He emigrated as a young child with his family to New South Wales where his father established Burnettland near Raymond Terrace in the Hunter River district.
In 1834 he entered the service of the Survey department of New South Wales, spending a considerable period in the Illawarra district. Burrnett was selected by Sir Thomas Mitchell to lead a survey to trace the Great Dividing Range from south of Hanging Rock northward towards Moreton Bay. Burnett set off in October 1841 with Roderick Mitchell (son of Thomas Mitchell) as second-in-command of the party. After many difficulties, the range was traced to about the 30°S and then the party headed for Brisbane arriving September 1842.
In 1845, he was appointed a Commissioner of Crown Lands.
Burnett subsequently undertook surveys of the Clarence River and Richmond River. In 1846, he was appointed in charge of the surveys in Moreton Bay and settled in Brisbane. In 1846 to 1847 he explored north of Moreton Bay in the area of the Mary River and Burnett River. His efforts in exploring Queensland (as it is now known) were recognised by New South Wales Governor Charles Augustus FitzRoy by naming the Burnett River and the surrounding area after Burnett.
