Physiographically, Australasia includes New Zealand, Australia (including Tasmania), and Melanesia: New Guinea and neighbouring islands north and east of Australia in the Pacific Ocean. The designation is sometimes applied to all the lands and islands of the Pacific Ocean lying between the equator and latitude 47° south. The independent country of Papua New Guinea also includes approximately 600 offshore islands. Most of Australasia lies on the southern portion of the Indo-Australian Plate, flanked by the Indian Ocean to the west and the Southern Ocean to the south. Peripheral territories lie on the Eurasian Plate to the northwest, the Philippine Plate to the north, and in the Pacific Ocean – including numerous marginal seas – atop the Pacific Plate to the north and east.
