Covering a total area of 7.69 million square kilometres, mainland Australia is the worldĄŻs largest island - but smallest continent.
In distance, the continent stretches about 3700 kilometres from north to south and 4000 kilometres from east to west, making it the sixth-largest nation after Russia, Canada, China, the United States and Brazil.
Australia is also the only continent that is governed as a single country. It is sometimes informally referred to as an 'island' continent, surrounded by oceans.
Our ocean territory is also the third-largest in the world, spanning three oceans and covering around 12 million square kilometres. We also have one of the most urbanised and coast-dwelling populations in the world, with more than 80 per cent of residents living within 100 kilometres of the coastline. Australia currently has a population of almost 23 million people.
