Australia is a continent and a country
The continent of Australia is sometimes referred to as 'Sahul', 'Australinea', or 'Meganesia' to differentiate it from the country of Australia. The country of Australia comprises most of the continent and is sometimes informally referred to as an 'island continent', as it is highly urbanised and surrounded by oceans. The name 'Australia' is derived from the Latin 'Terra Australis' or 'Terra Australis Incognita', meaning 'unknown southern land'.
The continent of Australia consists of the country of Australia, as well as New Zealand, Papua New Guinea, and numerous islands in the Pacific Ocean, including Tasmania, New Guinea, and thousands of tiny, tropical islands in the Melanesian, Micronesian, and Polynesian regions. These islands are often collectively referred to as Oceania, and there are 14 independent countries and 12 dependent overseas territories within this grouping.
Australia, the country, is a relatively prosperous independent country with a diverse landscape, including deserts, tropical rainforests, savannas, and mountain ranges. It has a strong Anglo-Celtic cultural orientation that is being transformed by immigration, bringing in culinary traditions and contributing to fusion dishes. Australia is a leading exporter and consumer of wine and ranks highly in beer consumption, with breweries in each state and territory.

The continent of Australia is also called Australasia
Australia is a country comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands. It is the world's smallest continent and the sixth-largest country by total area. Australia is sometimes considered the world's largest island and is often dubbed the "island continent".
The continent of Australia is sometimes referred to as Australasia. Australasia is a subregion of Oceania, which includes Australia, New Zealand (overlapping with Polynesia), and sometimes New Guinea and surrounding islands (overlapping with Melanesia). The term was coined in 1756 by Charles de Brosses, who derived it from the Latin for "south of Asia". The term was used in the 19th century to refer to the "Australasian colonies", specifically the British colonies south of Asia: New South Wales, Queensland, South Australia, Tasmania, Western Australia, Victoria, and New Zealand.
The name "Australasia" was originally used to refer to the Pleistocene landmass before the 1970s. This usage is considered obsolete today, as the term now generally refers to a wider region that includes lands like New Zealand that are not on the same continental shelf. The continent of Australia is also known by the names Sahul, Australinea, or Meganesia to differentiate it from the country of Australia. These names refer to the continent's landmasses, which sit on the Australian continental plate, including mainland Australia, Tasmania, and the island of New Guinea.
In some countries, such as Argentina, Brazil, and China, Oceania is treated as a continent, and Australia is viewed as an island nation. In other countries, such as Kazakhstan, Poland, and Russia, Australia is considered a continent, while Oceania is regarded as a "part of the world".

The Oceania region includes Australia and 11 Pacific Island countries
The Oceania region also includes 11 Pacific Island countries. These are New Zealand, Papua New Guinea, American Samoa, the Cook Islands, Fiji, Guam, Kiribati, the Marshall Islands, Nauru, Samoa, and Tonga. These countries are spread across the South and Central Pacific Ocean.
The term Oceania was originally a "great division" of the world in the 19th century. It included Australia, New Zealand, and the Pacific islands. Over time, the definition of Oceania has evolved, and it now encompasses a broader range of countries and territories in the Pacific region.
The Pacific Island countries within Oceania vary significantly in size and population. For example, Nauru is the smallest independent country in Oceania, covering an area of only 21 square kilometres, while Papua New Guinea is the largest country in Oceania after Australia, with a land area of 462,840 square kilometres.
Australia and the Pacific Island countries of Oceania share a diverse natural environment and unique ecosystems. The region is known for its tropical rainforests, savannas, mountain ranges, and coral reefs, such as the Great Barrier Reef off the coast of Australia. The rich biodiversity of the region attracts tourists from around the world, who come to explore the natural beauty and cultural heritage of Oceania.
