The name "Australia" is derived from the Latin word 'australis' (meaning "southern") In 1644, Dutch explorer Abel Tasman named the land "New Holland", but the name Australia was popularised by the explorer Matthew Flinders and the British government made it official. Colloquial names for Australia include "Oz" and "Down Under"

Occupying an area of approximately 344,400 square kilometres (133,000 sq miles), the Great Barrier Reef in the Coral Sea, off the coast of Queensland, Australia, is the world's biggest single structure made by living organisms and can be seen from outer space. There is a postbox (mail box) located on the Quicksilver viewing platform at Agincourt Ribbon Reef, on the outer Great Barrier Reef, from which you can send postcards and mail. It’s the only place where you can get the special Great Barrier Reef stamp!
