What You'll Learn
Australia is a continent, not a province or island
Australia is a continent, not a province or an island. It is surrounded by the Indian and Pacific Oceans and is separated from Asia by the Arafura and Timor Seas. Australia is the smallest of the seven continents, with a total land area of 8.56 million square kilometres (3,310,000 sq mi). It is also the sixth-largest country in the world and the largest in Oceania.
The continent of Australia includes the mainland, the island of Tasmania, and numerous smaller islands. Australia has 8,222 islands within its maritime borders, ranging from small rocks that are not covered by water at high tide to islands that are more than twice the size of the Australian Capital Territory. The largest of these islands is Tasmania, which has a land area of 64,519 square kilometres (24,911 sq mi) and a population of 570,000. Other large islands include Melville Island in the Northern Territory, Kangaroo Island in South Australia, and K'gari in Queensland, which is the world's largest sand island.
Australia is sometimes referred to as an "island continent" because it is surrounded by water and is relatively small compared to other continents. However, according to Britannica, an island is a mass of land that is "entirely surrounded by water" and "smaller than a continent." By this definition, Australia cannot be considered an island because it is already a continent.
The state of Tasmania, which is part of the Australian continent, can also be considered a province. It includes the main island of Tasmania, which makes up 94% of the state's land area, as well as 334 smaller islands. The main island of Tasmania does not have a defined name and is sometimes referred to as the "Tasmanian mainland."

It is one of six federated states in Australia, which include New South Wales, Queensland, South Australia, Victoria, and Western Australia. Tasmania is the largest island within Australia's maritime borders, spanning 64,519 square kilometres (24,911 square miles).

Tasmania has a population of approximately 570,000 people and is known for its natural beauty and unique wildlife.
The state of Tasmania is located in the southern part of Australia, separated from the mainland by the Bass Strait. It is situated in the geographical region of Oceania, specifically the subregion of Australasia. Tasmania has a rich history, with Aboriginal Australians, including Torres Strait Islanders, inhabiting the island for thousands of years. The Aboriginal Australian culture is one of the oldest continuous cultures in the world.
Tasmania has a unique position as both a state and an island within Australia. It has its own constitution and governing bodies, including a legislature, executive government, and judicial system. As an island, Tasmania has a distinct character and identity, with its natural environment playing a significant role in shaping its culture and economy.
The island of Tasmania is an integral part of Australia, contributing to its diversity and beauty. Its status as both a state and an island gives Tasmania a unique perspective within the Australian context, offering a blend of mainland connectivity and insular independence.

Macquarie Island is a distant Australian territory
The island was discovered by Frederick Hasselborough, an Australian, on July 11, 1810, while searching for new sealing grounds. Hasselborough claimed the uninhabited island for Britain and annexed it to the colony of New South Wales. The island was named after Colonel Lachlan Macquarie, the Governor of New South Wales from 1810 to 1821.
Macquarie Island is ecologically significant, serving as the annual nesting site for the entire royal penguin population. It is also a part of the Antipodes Subantarctic Islands tundra ecoregion. The island has been designated as a wildlife sanctuary and a state reserve, and it plays a crucial role in conservation efforts. In 1997, Macquarie Island was recognised as a UNESCO World Heritage Site due to its unique geological features.
The island is the exposed crest of the undersea Macquarie Ridge, formed by the interaction between the Indo-Australian tectonic plate and the Pacific plate. This geological formation provides insights into the composition of the oceanic crust and the upper mantle, as well as evidence of tectonic processes that have been active for hundreds of millions of years. Macquarie Island is also the only place on Earth where rocks from the Earth's mantle are actively exposed above sea level.
Macquarie Island and its surrounding ecosystem have faced challenges due to the presence of invasive species such as rabbits, rats, and mice. These pests have caused soil erosion, cliff collapses, and the destruction of seabird nests. However, through joint efforts by the Australian and Tasmanian governments, successful eradication programs have been implemented to protect the island's World Heritage values.

K'gari is the world's largest sand island
Australia has 8,222 islands within its maritime borders. One of these islands is K'gari, formerly known as Fraser Island, which is located along the south-eastern coast in the Wide Bay–Burnett region of Queensland. It is the world's largest sand island, spanning 1,840 square kilometres (710 square miles) or 184,000 hectares. K'gari is about 123 kilometres (76 miles) long and 22 kilometres (14 miles) wide, with sand dunes reaching 244 metres in height. The island is characterised by its diverse landscapes, including rainforests, eucalyptus woodland, mangrove forests, wallum and peat swamps, sand dunes, and coastal heaths.
K'gari's sand dunes are not static but are constantly moving at a rate of 1 to 2 metres per year due to year-round winds from the southeast. This dune movement, known as sandblowing, shapes the island's landscape by forming hills and intersecting with waterways and forests. The sand on K'gari is also notable for its rich plant life, supported by naturally occurring mycorrhizal fungi that release nutrients in a form absorbable by plants. This abundance of plant life distinguishes K'gari from many other sand dunes, where vegetation is often sparse or non-existent.
The island is a part of the traditional lands of the Butchulla people, who originally named it "K'gari", meaning "paradise". In their culture, K'gari represents "a beautiful white spirit" who provides food, water, and shelter, and in return, the Butchulla people protect and preserve her. This deep cultural connection between the Butchulla people and the land was formally recognised in 2021 when the World Heritage Area within Great Sandy National Park, along with surrounding waters and nearby mainland areas, was officially renamed "K’gari (Fraser Island)".
K'gari has a rich history beyond its connection to the Butchulla people. In 1836, it was the site of a shipwreck that stranded Eliza Fraser, after whom the island was named during European settlement. During World War II, the island served as a commando school and battery fortifications were established to defend nearby Brisbane. Today, K'gari is a popular tourist destination, attracting up to 500,000 visitors each year. It offers unique attractions, such as the Maheno shipwreck and scenic four-wheel-drive adventures, as well as opportunities for fishing and exploring military relics.
