• The continent of Australia is sometimes known by the names Sahul, Australinea, or Meganesia to distinguish it from the country of Australia, and consists of the landmasses which sit on Australia’s continental plate. This includes mainland AustraliaTasmania, and the island of New Guinea, which comprises Papua New Guinea and Western New Guinea (a province of Indonesia).[1][2][3][4][5] The name « Sahul » takes its name from the Sahul Shelf, which is part of the continental shelf of the Australian continent.
  • The term Oceania, originally a « great division » of the world, was replaced by the concept of Australia as a continent in the 1950s. Today, the term Oceania is often used to denote the region encompassing the Australian continent, Zealandia and various islands in the Pacific Ocean that are not included in the seven-continent model.
