Australia is situated in the middle of the tectonic plate, and therefore has no volcanism, although it may sometimes receive minor earthquakes. The terrain is mostly heavily weathered, low plateau with deserts, rangelands and a fertile plain in southeast. Tasmania and the Australian Alps contain a number of permanent icefields and numerous glaciers.

Much of Australia's culture is derived from European and more recently American roots, but distinctive Australian features have evolved from the environment, aboriginal culture, and the influence of Australia's neighbours. The vigor and originality of the arts in Australia—films, opera, music, painting, theater, dance, and crafts—are achieving international recognition.

With a population of approx. 170,000 people in the city proper (known as the "city of Sydney") and a metropolitan area population exceeding 4 million, the Sydney metropolis is the larger of the two main financial, transport, trade and cultural centres of Australia (the other being Melbourne, Sydney's long term rival to the title of pre-eminent Australian city).

Canberra is approximately 3 hours by road from Sydney on the Hume Highway (National Highway 23) and Federal Highway, 7 hours by road from Melbourne on the Hume Highway and Barton Highway (National Highway 25), and 2 hours on the Monaro Highway (National Highway 23) to the snow ski fields of the Snowy Mountains and the (Mount) Kosciuszko National Park.

Much of the area around Adelaide was once used for wine grape production, so that wine growing districts (such as the Barossa Valley, for which Adelaide and South Australia are well known) remain within a short drive of the city outskirts.

The land that is now Australia was first discovered by Europeans in 1522 by the Portuguese explorer Cristóvão de Mendonça, but it was only in the 17th century that the island continent became the subject of European exploration, with several expeditions sighting Terra Australis: The Dutch explorer Willem Jansz (1606), the Portuguese explorer Luis Vaez de Torres in Spanish service (1607), and the Dutch explorers Jan Carstensz (1623), Dirk Hartog and Abel Tasman (1642), after whom is named the island of Tasmania, but which he himself originally named after Anthoonij van Diemenslandt.
