Australasia

Australasia is a geographical subregion of Oceania with ambiguous extents. The term is used in a number of different contexts, including geopolitically, physiogeographically, philologically, and ecologically, where the term covers several slightly different but related regions. Depending on the definition used, it may also include insular parts of Asia. Australasia always includes Australia and New Zealand, and often also includes New Guinea. In its broadest sense, it may include the entire Malay Archipelago (Nusantara).
