What You'll Learn
Australia is an island continent
The continent of Australia includes mainland Australia, Tasmania, the island of New Guinea, the Aru Islands, the Ashmore and Cartier Islands, and most of the Coral Sea Islands, among others. It is surrounded by the Indian and Pacific Oceans, as well as the Coral and Timor Seas. Australia is the sixth-largest country in the world by total area and is nearly four times the size of Greenland, the largest island in the world.
The first people to arrive in Australia came from Indonesia and lived there in isolated communities for tens of thousands of years before the first Europeans arrived. The first European sighting and landing on the continent of Australia were made by the Dutch in 1606, and the eastern half of the island was claimed by Great Britain in 1770. In 1813, Samuel Butler referred to Australia as "an immense island, which some geographers dignify with the appellation of another continent".
Australia is so large that it is regarded as a continent, but it is also sometimes referred to as an island because it is surrounded by water. However, according to geographers, islands are "smaller than continents". Despite this, the United States-based scientific agency considers all landmasses surrounded by ocean water, including continental mainlands, as islands. Australia has a number of large islands, including the world's largest sand island, K'gari, located off the coast of southern Queensland.

Australia is the world's sixth-largest country
The continent of Australia includes mainland Australia, Tasmania, the island of New Guinea, the Aru Islands, the Ashmore and Cartier Islands, and most of the Coral Sea Islands, among others. Australia is nearly four times the size of Greenland, which is considered the world's largest island. Australia has a population of approximately 24 million people, with most living in cities along the east coast. The largest city is Sydney, and the country's capital is Canberra.
The name Australia is derived from the Latin word 'australis', meaning "southern". The country is officially known as the Commonwealth of Australia, which came into being when the Federal Constitution was proclaimed by the Governor-General, Lord Hopetoun, on 1 January 1901. On this date, the six colonies joined to form the Commonwealth of Australia, and a system of federalism came into operation.
The first people to arrive in Australia came from Indonesia and lived there in isolated communities for tens of thousands of years before the first Europeans arrived. The first European sighting of Australia was in 1606 by Dutch navigator Willem Janszoon, and the eastern half of the island was later claimed by Great Britain in 1770.

Australia is south of Asia
Australia is the largest island in the Southern Hemisphere. It is located south of Asia and is so large that it is regarded as a continent. The continent of Australia is sometimes known technically as Sahul, Australia-New Guinea, Australinea, or Meganesia to distinguish it from the country of Australia. It is located within the Southern and Eastern Hemispheres, near Maritime Southeast Asia. The name Australia comes from the Latin word australis, meaning "southern".
Australia is nearly four times the size of Greenland, the next largest island. Australia is the smallest of the seven traditional continents and is the sixth-largest country by total area. It has a population of around 24 million people, with most living in cities along the east coast. The largest city is Sydney, and the capital is Canberra.
The continent includes mainland Australia, Tasmania, the island of New Guinea, the Aru Islands, the Ashmore and Cartier Islands, and most of the Coral Sea Islands, among others. It has a continental shelf overlain by shallow seas that divide it into several landmasses, including the Arafura Sea and Torres Strait between mainland Australia and New Guinea, and Bass Strait between mainland Australia and Tasmania.
Australia has a diverse flora, with many unique adaptations to aridity and fire, including scleromorphy and serotiny. These adaptations are common in species from families such as Proteaceae, Myrtaceae, Fabaceae, and Casuarinaceae. Typical Southern Hemisphere flora include the conifers Podocarpus (eastern Australia and New Guinea), the rainforest emergents Araucaria (eastern Australia and New Guinea), Nothofagus (New Guinea and Tasmania), and Agathis (northern Queensland and New Guinea).
The history of Australia is fascinating. The first people to arrive in Australia came from Indonesia and lived there in isolated communities for tens of thousands of years before the first Europeans arrived. The Dutch were the first Europeans to explore the continent, followed by the famous British explorer Captain Cook. The eastern half of the island was claimed by Great Britain in 1770, and it was used as a place to transport convicts from Britain. The first prison colony was founded in 1778 at Botany Bay, just south of modern-day Sydney.
In the mid-19th century, a gold rush significantly increased Australia's population. On 1 January 1901, the six British colonies joined to form the Commonwealth of Australia, and it became a dominion of the British Empire in 1907. Australia is now an independent country, with the British Queen as its head of state.

Australia is a country and a continent
The continent of Australia is sometimes referred to as Sahul, Australinea, or Meganesia to distinguish it from the country of Australia. The continent 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. It is situated in the geographical region of Oceania, in the subregion of Australasia.
Australia is sometimes considered the world's largest island and is often dubbed the "island continent". However, geographers typically define islands as masses of land that are "entirely surrounded by water" and "smaller than a continent". By this definition, Australia cannot be an island because it is already a continent.
Australia is a federal parliamentary democracy and constitutional monarchy. It has a highly urbanised population of almost 28 million, with most people living in cities along the east coast. The country has the world's 9th largest immigrant population and the 14th-largest economy. It ranks highly for quality of life, health, education, economic freedom, civil liberties, and political rights.

Australia is made up of several landmasses
Australia is often referred to as an island continent. It is surrounded by the Indian and Pacific Oceans and is located in the Southern and Eastern Hemispheres. The continent of Australia is made up of several landmasses, including the mainland, Tasmania, the island of New Guinea, the Aru Islands, the Ashmore and Cartier Islands, and the Coral Sea Islands, among others. The continent also includes a continental shelf overlain by shallow seas, which divide it into several distinct landmasses.
The definition of a continent varies among geographers, and there is no strict scientific definition. Some consider Australia to be the largest island in the Southern Hemisphere and the world. However, others argue that Australia is a continent and not an island because it is a large landmass. The debate arises because the definition of an island is typically a mass of land entirely surrounded by water and smaller than a continent.
Historically, Australia has been referred to as an island country because of its lack of land borders. The continent was first posited in antiquity and appeared on maps between the 15th and 18th centuries. Legends of Terra Australis Incognita, or the "unknown land of the South," date back to Roman times and earlier, although they were not based on any documented knowledge of the continent. In 1606, Dutch navigator Willem Janszoon made the first documented European landing on the continent of Australia in Cape York Peninsula. By the late 18th century, some geographers considered Australia a continent, and in 1813, Samuel Butler referred to it as an "immense island."
Today, Australia is considered the smallest of the seven traditional continents. It is nearly four times the size of Greenland, which is considered the world's largest island. Australia is so large that it is further divided into several territories and states, including the Australian Capital Territory and the state of New South Wales.
