Sir Augustus Charles Gregory (1 August 1819 – 25 June 1905) was an English-born Australian explorer and surveyor. Between 1846 and 1858 he undertook four major expeditions. He was the first Surveyor-General of Queensland. He was appointed a lifetime Member of the Queensland Legislative Council. Early years Augustus Charles Gregory was born at Farnsfield, Nottingham, England. He was the second of five brothers born to Joshua Gregory and Frances Churchman. Among his brothers were Francis Thomas Gregory, who also became a noted explorer. Joshua William Gregory, born 1815, died 20 September 1850 aged 35. Augustus Charles Gregory, born 1 August 1819, died 1905 aged 86 Francis (Frank) Thomas Gregory, born 1821. Henry Churcham Gregory, born 1823, died London 29 July 1903 aged 79 years Charles Frederick Gregory, born 1825. A. C. Gregory was educated privately by tutors and later by his mother.
