Terra Australis became a federation on the flattest continent
The Commonwealth of Australia covers about 7,688,287 km²—sixth-largest country and Earth's flattest continent—plus Tasmania and lesser islands. Aboriginal ancestors arrived 50,000–65,000 years ago; at British settlement they spoke over 250 languages. Nearly 29 million people cluster on the eastern seaboard under a Canberra capital.
The Commonwealth of Australia covers the mainland continent, Tasmania, and many smaller islands across about 7,688,287 square kilometres—sixth largest nationally—and is often called the flattest, driest inhabited continent. Deserts fill much of the interior while tropical forests belt parts of the north; megadiversity follows from that climatic spread.
Aboriginal ancestors arrived from Southeast Asia some fifty to sixty-five thousand years ago. By British arrival they spoke more than two hundred fifty languages. Dutch charts labelled much of the coast New Holland in the seventeen-hundreds; British colonisation began with the 1788 New South Wales penal colony. Matthew Flinders helped popularise the name Australia after circumnavigating in 1803.
Today a federal parliamentary constitutional monarchy of six states and ten territories holds almost twenty-nine million people, heavily urban and concentrated on the eastern seaboard. Canberra is capital; Sydney and Melbourne each exceed five million. High foreign-born shares shape culture. Middle-power diplomacy includes UN, G20, APEC, and security ties such as ANZUS and AUKUS.
Mining, farming, and coastal services drive output far from the sparse centre. Size alone misleads without the coastal population pattern and deep Indigenous timeline. Seasonal fires, coral bleaching, and drought cycles now sit beside older frontier myths in public argument. Distance to Asian markets and Pacific neighbours still structures trade even when domestic politics feel inland. State rivalries over sport and investment remain loud precisely because the federation left strong regional centres intact.
