Why did they call Australia Australia?

Sea explorer Matthew Flinders was the one who first proposed the name "Terra Australis", which became "Australia", as a result of his circumnavigation of the continent. He suggested the name in his book "A voyage to Terra Australis", which was published in the year he died, in 1814. The name Australia was adopted in 1824. Prior to this, the continent was known as Terra Australis Incognita, or the Unknown Southern Land.
