Australia (continent) Australia, sometimes known in technical contexts by the names Sahul, Australinea or Meganesia, to distinguish it from the country of Australia, is a continent comprising mainland Australia, Tasmania, New Guinea, New Britain, and small neighbouring islands (such as Misool and Waigeo, just to the northeast of Maluku Islands at the edge of its continental shelf). Situated in the geographical region of Oceania, it is the smallest of the seven traditional continents in the English conception. Countries within the continent include Australia, Papua New Guinea and, partially, Indonesia.[1]
