The vast expanse of water between Asia and the Americas, with an area of 100 million square kilometers, is home to countless archipelagos and more than 10,000 islands.

Some Facts about Australia and Oceania

Oceania There are a variety of definitions of Oceania. The most plausible is to refer to the vast regions, island territories and adjacent seas in the Pacific Ocean, east of Maritime Southeast Asia and Australia and west of South America. (see the map below). How many countries are there in Oceania? In the vast area of Oceania, there are 14 independent countries and several dependent territories (see the list below). Australasia The region consisting of Australia, New Zealand, New Guinea, and neighboring islands in the Pacific Ocean is sometimes referred to as Australasia. Area Oceania covers an area of approximately 100 million square kilometers; this is about one-fifth of Earth's surface area. The water continent includes more than 10,000 islands. With a total land area (excluding Australia but including Papua New Guinea and New Zealand) of approximately 822,800 km² (317,700 sq mi), it is slightly larger than Turkey or somewhat smaller than half of Alaska. By far the largest country in Oceania in terms of area is Australia with 7,692,024 km², followed by Papua New Guinea with 462,840 km² and New Zealand with 270,467 km². The smallest independent country in Oceania is the island nation of Nauru, which covers an area of 21 km² (8 sq mi).

Australia

Map of Australia Australia is the smallest of the seven continents on Earth. The first people to discover and settle Australia about 50,000 years ago were the ancestors of the Aboriginal Australians. The ancestors of today's indigenous Australians migrated by sea from Southeast Asia during the Pleistocene. The discovery by the Europeans was a long time coming. It was not until 1606 that Dutch and Spanish explorers landed on the continent. In 1770 James Cook, a colorful figure in British colonial history, was on a quest to find the predicted Great South Land. He came across a vast stretch of unknown land when he arrived on the east coast of Australia, and in the usual blunt British fashion, he claimed the territory for the British Crown. Between 1788 and 1868, the British used the continent as a penal colony. Australia became independent from the United Kingdom in several steps, and it was not until the 3rd of March 1986 that Australia gained full independence from Great Britain. Area of Australia Including the adjacent island of Tasmania, Australia covers an area of 7,692,024 km² (2,969,907 sq mi), which corresponds to about 5.6% of Earth's landmass. In comparison, Australia is slightly smaller than the contiguous United States. One country, Australia, occupies the continent. Map of the Regions in Oceania The map shows the various, partly overlapping regions of Oceania: Micronesia, Melanesia, Polynesia, and Australasia, as well as the parallel of latitude 23°26ʹ south, known as the Tropic of Capricorn. Depicted on the map is also the course of the International Date Line (IDL) along the 180th meridian (180° longitude), with diversions to pass around some island groups such as Kiribati.

Other deserts are the Great Sandy Desert, the Tanami Desert, the Simpson and the Gibson deserts, and the Strzelecki Desert.
