For centuries the landmass thought to exist in the southern hemisphere was named 'terra australis incognita', the 'unknown southern land.' 'Australis' is the Latin term for 'southern.' In 1627 the Dutch ship Gulden Zeepaard had sailed along the southern coast reaching present day Fowler's Bay. In deference to the Dutch discoveries made in the seventeenth century along the western and northern coastline, the western section of the continent was referred to as 'New Holland.' The south coast of Van Diemen's Land was charted by Abel Tasman in 1642.
The eastern section of the continent was named 'New South Wales' by James Cook. The southern coast, and the actual extent of the continent remained 'unknown' until Flinders' voyage - some thought that there might be a strait separating New South Wales from the western section.
Matthew Flinders was the first to circumnavigate the continent, and chart the 'unknown coast.' By 1803 the complete outline of the Great Southern Land was mapped, but Flinders' detention at Mauritius delayed the publication of his journal and atlas until their eventual appearance in 1814. Flinders used 'Terra Australis' on his charts. He recognised that now that he had determined that New South Wales and New Holland were one land, there should be a general name for the whole continent.
In the introduction to A voyage to Terra Australis, Flinders wrote:
Flinders' chart accompanying the book was entitled General Chart of Terra Australis or Australia. However, Flinders' patron Sir Joseph Banks preferred 'Terra Australis'. In 1817 Governor Macquarie of New South Wales received a copy of Flinders' book, and started to use 'Australia' in his official correspondence. Later explorer Phillip Parker King also used 'Australia' on his maps of the northern and western coasts, and by the end of the 1820s 'Australia' was commonly used as the continent's name.
