The Dictionary of Australasian Biography/Dalrymple, George Augustus Frederick Elphinstone
Dalrymple, George Augustus Frederick Elphinstone, First Speaker Legislative Assembly, Queensland, was the tenth son of Sir Robert Dalrymple Horn Elphinstone, Bart., by his marriage with Graeme, daughter of Colonel David Hepburn, and was born on May 6th, 1826. He went to Australia as aide-de-camp to the late Sir George Gipps, Governor of New South Wales, and became a partner with Mr. (now Sir Arthur) Hodgson in squatting ventures in the Moreton Bay district. He was one of the early explorers of what is now the colony of Queensland. In 1859 he explored the country between the parallels of 19° and 20° S., and greatly extended the knowledge of the country which Leichardt, Mitchell, Kennedy, and Gregory had primarily, opened up. In 1862 he made a second journey, and traced an opening from the Valley of Lagoons to Rockingham Bay in Queensland. Mr. Dalrymple, after whom the town of Dalrymple was named, sat in the Legislative Assembly of New South Wales before Queensland was severed from New South Wales, and soon after separation was effected entered the Legislative Assembly of Queensland, and became Colonial Secretary in Mr. (now Sir Robert) Herbert's second ministry in July 1866; but did not remain in the Government when it was reconstructed under Mr. Macalister (who took the portfolio of Colonial Secretary) in the following month. He died on Jan. 22nd, 1876.
