The world's smallest continent is Australia. Often referred to as the "island continent," Australia is surrounded by water, distinguishing it from larger landmasses that are also classified as continents. Geographically, it includes the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands. Australia has a diverse range of ecosystems and climates, ranging from desert to tropical rainforests. Culturally, it is home to Aboriginal and Torres Strait Islander peoples, and it has a rich history that predates European settlement. Its status as a continent is unique due to its size and geographical features.
