Australia is the only country that occupies an entire continent by itself.

The longer version

A continent is usually defined as a large continuous mass of land set apart by geology or by convention. Most continents hold many countries. In this case one political border covers the whole mainland along with nearby islands, so the two terms line up in an unusual way.

Geologists sometimes count the surrounding shelf as part of a larger region that includes neighbouring islands. The mainland also sits on its own tectonic plate and separated from other landmasses long ago, which allowed distinctive plants and animals to develop. Isolation shaped the wildlife found there, from marsupials to unusual reptiles.
