Australasia is the area that includes Australia, New Zealand, New Guinea, and the many smaller islands in the vicinity, most of which are the eastern part of Indonesia. The name was coined by Charles de Brosses in Histoire des navigations aux terres australes (1756). He derived it from the Latin for "south of Asia" and differentiated the area from Polynesia and the south east Pacific (Magellanica).
