Lieutenant Owen Gorman
Lieutenant Owen Gorman was the last commandant of the settlement. Very little is known of his life. He served at Moreton Bay from July 1839 to May 1842. Gorman was the only one of the Commandants to rise from the ranks. His career at Moreton Bay was not a particularly commendable one, and he was relieved from his position as Magistrate because of his immoral association with a convict woman.
Lieutenant George Gravatt
Lieutenant George Gravatt was appointed to take command of the settlement in 1839. Not a great deal is known of his life, beyond that he was born at Woolwich, England, on 25 July 1815, and was Commissioned as an Ensign in the 28th Foot Regiment on 25 September 1837. His promotion to Lieutenant was dated 24 May 1839, which was a few days after his appointment as Commandant of Moreton Bay.
Wrapping it up
The careers of both Lt. Gravatt and Lt. Gorman are not sufficiently well known to allow for any worthwhile appraisal of their lives. It would be quite unfair to criticise Lt. Gorman for his moral conduct at Moreton Bay, unless a great deal more was known of his everyday life, as certain travelers have spoken very highly of him.
Moreton Bay Convict Settlement did much towards hastening the development, not only of the State of Queensland, but also the greater part of New South Wales north of Sydney.
