In 1798, Bass and Flinders, sailed the "Norfolk", around Van Diemen's Land, proving that it was an island. They visited the estuary of the Derwent River, found and named by Captain John Hayes in 1793. Bass made a report which led to it being chosen for the future city of Hobart in 1803. When they got back to Sydney, Flinders recommended to Governor John Hunter that the passage between Van Diemen's Land and the mainland be called Bass Strait.
