Who was the first to circumnavigate Australia?

Captain Matthew Flinders RN was an English navigator and cartographer, who was the leader of the first circumnavigation of Australia and identified it as a continent. Flinders made three voyages to the southern ocean between 1791 and 1810. In the second voyage, George Bass and Flinders confirmed that Van Diemen's Land (now Tasmania) was an island. In the third voyage, Flinders circumnavigated the mainland of what was to be called Australia, accompanied by Aboriginal man Bungaree.
