 HMCS Integrity was a cutter built by the Colonial Government of New South Wales in 1804. She was the first vessel ever launched from a New South Wales dockyard and carried goods between the colony's coastal settlements of Norfolk Island, Newcastle, Van Diemen's Land and Port Jackson. In 1804 she took part in a series of voyages to Van Diemen's Land with the aim of founding a colony at Port Dalrymple, the site of the modern settlement of George Town, Tasmania.
