Australia is a continent surrounded by oceans, which has led to it often being referred to as an island continent. It is the smallest of the world's seven continents and one of the largest countries on Earth. The continent of Australia includes the country of Australia, as well as mainland Australia, Tasmania, and the island of New Guinea, which comprises Papua New Guinea and Western New Guinea. While there is no strict scientific definition of a continent, several factors are commonly used to distinguish a continent from an island, including size, geological and biological distinctions, and anthropological differences.

Australia is an island continent surrounded by oceans
Australia is a continent surrounded by oceans. It is the smallest of the seven continents, lying between the Pacific and Indian Oceans in the Southern Hemisphere. The continent includes mainland Australia, Tasmania, the island of New Guinea, the Aru Islands, the Ashmore and Cartier Islands, most of the Coral Sea Islands, and some other nearby islands.
The country of Australia is mostly on a single landmass and comprises most of the continent. It is sometimes informally referred to as an island continent. Australia is significantly larger than its fringing islands, which include the world's largest sand island, K'gari, in the Pacific, Indian, and Southern Oceans, and the Coral and Timor Seas.
There is no strict scientific definition of a continent, but several commonly accepted criteria distinguish a continent from an island. One criterion is geological distinction: while Australia sits on its own continental plate, Greenland shares a tectonic plate with North America. Another criterion is biological distinction: a large percentage of Australia's plant and animal species are unique to the continent, whereas fewer of Greenland's species are unique. A third criterion is anthropological distinction: Aboriginal people are limited to Australia, while indigenous Greenlanders are part of a group of peoples found throughout the Arctic, including parts of Canada, the United States, and Russia.
Australia's continental status is also supported by its cultural uniqueness and local belief in its status as a continent. Additionally, Australia meets the criterion of tectonic independence from other continents. While there is no official consensus on what defines a continent, Australia satisfies many of the commonly accepted criteria.
In some countries, such as Argentina, Brazil, China, and France, Oceania is treated as a continent, and Australia is considered an island nation. However, the continent of Australia, also known as Sahul, Australinea, or Meganesia, is distinct from the country of Australia and consists of landmasses that sit on the Australian continental plate.

Australia is the smallest continent
Australia is a continent surrounded by the Indian and Pacific Oceans in the Southern Hemisphere. It is the smallest of the seven continents, with a land area of about 7.75 million square kilometres. The continent includes mainland Australia, Tasmania, the island of New Guinea, the Aru Islands, the Ashmore and Cartier Islands, most of the Coral Sea Islands, and some other nearby islands.
The country of Australia comprises most of the continent and is sometimes informally referred to as an island continent. However, it is not an island, as there is no mainland it can be compared to. Australia is the dominant land mass on its continental plate, and it is significantly larger than its surrounding islands.
The continent of Australia is also known as Sahul, Australinea, or Meganesia to distinguish it from the country of Australia. The term Oceania, which includes Australia and other islands in the Pacific, was originally used as a "great division" of the world in the 1810s. In the 1950s, the concept of Australia as one of the world's continents became popular in English-speaking countries, replacing the term Oceania.
There is no strict scientific definition of a continent, but several commonly accepted criteria distinguish a continent from an island. These include tectonic independence, unique flora and fauna, cultural uniqueness, and local belief in continental status. Australia meets several of these criteria, while Greenland, the largest island, does not. For example, Australia has a high number of unique plant and animal species, whereas fewer of Greenland's species are unique. Additionally, the Aboriginal people are limited to Australia, while indigenous Greenlanders are part of a group of peoples found throughout the Arctic.

Australia is a country
Australia, the country, is a relatively prosperous independent country and a member of the Commonwealth. It has the world's 14th-largest economy and the second-highest Human Development Index globally. It is highly urbanized and has the world's ninth-largest immigrant population. The capital city is Canberra, and its most important economic and cultural centres are Sydney and Melbourne.
Australia is surrounded by oceans and is sometimes referred to as an island continent. However, for Australia to be considered an island, there would have to be a mainland, and Australia is not connected to another continent. Australia is the dominant land mass on its continental plate, and its size is nearly four times that of Greenland, which is considered an island.
Australia meets several of the criteria used to distinguish continents from one another. These include tectonic independence from other continents, unique flora and fauna, cultural uniqueness, and local belief in continental status. Aboriginal people are limited to Australia, and a large percentage of Australia's plant and animal species can be found nowhere else in the world.

Australia is not an island
Australia is the smallest continent and one of the largest countries on Earth, lying between the Pacific and Indian Oceans in the Southern Hemisphere. Its closest mainland continent is Asia. The continent of Australia includes mainland Australia, Tasmania, the island of New Guinea (Papua New Guinea and Western New Guinea), the Aru Islands, the Ashmore and Cartier Islands, most of the Coral Sea Islands, and some other nearby islands.
Australia is sometimes informally referred to as an "island continent" because it is a single landmass surrounded by oceans. However, this term is used to distinguish it from the many islands that are part of the continent of Australia, such as K'gari, the world's largest sand island, and Macquarie Island, which is one of Australia's most distant possessions.
The continent of Australia is also sometimes known as Oceania or Australasia to differentiate it from the country of Australia. Oceania includes not only Australia but also New Zealand, Micronesia, and other island nations and territories in the Pacific Ocean.
