The Australasia Eco-region is delineated to be an unique eco-region based on the principles of biodiversity occurrence and comprehensive eco-geographic features. The Australasia Eco-region consists of Australia, New Zealand, eastern Indonesia, East Timor, Papua New Guinea and their surround areas. The Selat Lombok and Selat Makassar separates the Australasia Eco-region and the Asia Tropical Humid & Semi-Humid Eco-region. The region’s most eastern part includes Bismarck Archipelago, Solomon Islands, New Hebrides Islands, and the eastern coastline of New Zealand. The Tasmania Island of Australia is the most southern island of the region. The boundary data of the Australasia Eco-region is developed and based on Google earth images. Geographically, the Australasia Eco-region ranges between 54o46＇38〞S to 4o48＇27〞N，and 112o34＇11〞E to 175o49＇32〞W. The total land area of this region is 9,223,438.42 km2; and the coastal lines total 200,950.20km, among them 46,006.72km around Australia. There are 17,035 Islands besides Australia continent, the minimum area of the islads is 75km2. The largest island is the New Guinea Island, which area is 768,603.81 km2. In terms of bio-climate, this eco-region covers tropical, subtropical, and temperate zones, and includes humid, semi humid, semi arid, and arid ecosystem. The combination of rich bio-climates and landforms sustains a rich biodiversity and forms a unique Australasia biodiversity and ecosystems. The dataset is archived in kmz and shp formats, in which 5 data files are in kmz format; both polylines and polygons data are included in the shp data format. The dataset is compressed to 400MB.
