In terms of area, which is the smallest continent?

The continent of Australia, sometimes known in technical contexts by the names Sahul, Australinea or Meganesia to distinguish it from the country of Australia, consists of the land masses which sit on Australia's continental plate. This includes mainland Australia, Tasmania, and the island of New Guinea.

With a total land area of 8.56 million square kilometers (3,310,000 sq mi), the Australian continent is the smallest, and second-lowest human inhabited (after Antarctica) continent on Earth.
