Australia itself is the smallest continent on Earth, at about 3 million square miles, and is sometimes defined as an island. There are 8,222 islands within Australia's maritime borders, ranging from small rocks covered at high tide to islands more than twice the size of the Australian Capital Territory. The islands larger than 1,000 square kilometres include Tasmania, Melville Island, Kangaroo Island, Groote Eylandt (the Big Island), Bathurst Island, K'gari, Flinders Island, King Island, and Mornington Island.

What You'll Learn
Australia: continent or island?
Australia is a continent surrounded by thousands of islands, including the world's largest sand island, K'gari. Australia is nearly four times larger than Greenland, the world's biggest island.
While there is no strict scientific definition of a continent, there are several criteria that distinguish a continent from an island. Geologically, Australia and most of Asia are situated on separate tectonic plates, whereas Greenland shares a tectonic plate with North America. Biologically, a large percentage of Australia's plant and animal species are unique to the continent, while fewer of Greenland's species are unique. Anthropologically, Aboriginal people are limited to Australia, while indigenous Greenlanders are part of a group of peoples (the Inuit) found throughout the Arctic, including parts of Canada, the United States, and Russia.
In terms of size, Australia is about 3 million square miles (7.7 million square km), making it the smallest continent on Earth. It is surrounded by numerous islands within its maritime borders, including Tasmania, Melville Island, Kangaroo Island, Groote Eylandt, Bathurst Island, Flinders Island, King Island, and Mornington Island.
Australia is considered a continent due to its large size, unique flora and fauna, and anthropological distinctions. However, the definition of a continent can vary among geographers, and mainland Australia is sometimes defined as an island as well as a continent.

K'gari: the world's largest sand island
Australia has 8,222 islands within its maritime borders, ranging from small rocks uncovered at high tide to islands over twice the size of the Australian Capital Territory. One of these islands is K'gari (also spelt K'gari), the world's largest sand island. Located just off the coast of southern Queensland, K'gari stretches over 123 kilometres in length and 25 kilometres at its widest point.
K'gari displays a diverse range of landscapes, from freshwater lakes to sand dunes, wetlands, crystal clear lakes, and dense rainforests. The island is famous for its coloured sands, which have been stained by decayed vegetation leaching into the sand for thousands of years. Some deposits are up to eight million years old. On the eastern beach, there is a site called The Cathedrals, which showcases this process.
In the 1970s, there was a successful movement to prevent sand mining on K'gari, resulting in an Australian government ban on this type of mining on the island. Today, K'gari is a World Heritage site, and the Great Sandy National Park covers 52,400 hectares on the northern half of the island.
Other large islands of Australia include Tasmania, Melville Island, Kangaroo Island, Groote Eylandt (an archaic Dutch spelling for "Big Island"), Bathurst Island, Flinders Island, King Island, and Mornington Island. Macquarie Island, located in the Southern Ocean, is one of Australia's most distant possessions, and it was nominated for inscription on the World Heritage Register in 1996 for its unique geological features.

Macquarie Island: Australia's most distant possession
Macquarie Island, a subantarctic island in the southwestern Pacific Ocean, is Australia's most distant possession. It is located about halfway between New Zealand and Antarctica, approximately 1,500 kilometres southeast of Tasmania. Macquarie Island is an exposed portion of the Macquarie Ridge, where the Australian Plate meets the Pacific Plate. The island is about 34 kilometres long and 5 kilometres wide, with an area of 128 square kilometres.
The island was discovered in 1810 by Frederick Hasselborough, an Australian, who claimed it 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 became a part of Tasmania, Australia, in 1880. In 1933, it was declared a wildlife sanctuary under the Tasmanian Animals and Birds Protection Act 1928. The status was changed to a conservation area in 1971, and then in 1972, it was redesignated as the Macquarie Island Wildlife Reserve.
Macquarie Island is a nature reserve managed by the Tasmanian Government through the Parks and Wildlife Service (PWS). The PWS also manages the island as a World Heritage Site on behalf of the Australian Government. The island is home to a variety of wildlife, including royal penguins, elephant seals, and rabbits. It is a popular destination for expeditions and cruises.
In 1977, Macquarie Island was declared a Biosphere Reserve under the UNESCO Man and the Biosphere Programme, and it was listed on the Australia Register of the National Estate. In 1978, the area of the state reserve was extended to include the offshore islets, and it was formally named the Macquarie Island Nature Reserve. On 5 December 1997, Macquarie Island was inscribed on the UNESCO World Heritage List as a site of major geoconservation significance due to its unique geological features.
