Michael Dennison (c.1767- ) was found guilty on 15 April 1785 at the Poole (Dorset) Quarter Sessions of stealing from a sloop. Sentenced to 7 years transportation he was sent to the Ceres hulk on 13 June 1785, where he remained until he embarked for New South Wales on the Alexander in January 1787, arriving in Sydney in January 1788 as part of the First Fleet.
On 26 December 1788 Dennison was sentenced to 150-200 lashes for stealing a bag with a pound of flour. He was sent to Norfolk Island on the Sirius in March 1790. On 24 May 1791 he received 25 lashes for neglect of duty. In July he was subsisting himself on a Sydney Town lot with 30 rods cleared.
Michael Dennison left Norfolk Island on the Atlantic in September 1792. It seems likely, as no later colonial records have been located, that he returned to England.
