Collins was commissioned as "Lieutenant Governor of a Settlement or Settlements to be formed on the Southern Coast of New South Wales to the northward of Basses Streights and on King's Island, or any other Island within the said Streights." He arrived at Port Phillip Bay on the southern coast of mainland Australia, where his commission was proclaimed on 17 Nov 1803. The settlement founded at Port Phillip was eventually abandoned, and Collins, along with the military and convicts, relocated to Van Diemen's Land, landing on the island on 16 Feb 1804. Collins used the style Lieutenant Governor of His Majestys Settlement at Hobart Town, but the establishment of other settlements prompted a change in the styles of the Lieutenant Governors to reflect the expansion of authority.
Following the death of Collins on 24 Mar 1810, the office of Lieutenant Governor remained vacant, while executive functions were exercised by the commandants at Hobart Town and Port Dalrymple. On 30 Jun 1812 the Settlement of Dalrymple became a dependency of the Settlement of Hobart Town. Lieutenant Governor Davey arrived and assumed the government of Van Diemen's Land on 20 Feb 1813.
Sorell took the oath of office in Sydney on 15 Mar 1817. His commission was read and published at Hobart Town on 9 Apr 1817.
This style was in use by the end of Sorell's term.
