Aboriginal and Torres Strait Islander cultures
Aboriginal and Torres Strait Islander peoples are the First Peoples of Australia. Their cultures are among the oldest continuing cultures in the world. In Kakadu National Park, in the far north, UNESCO says the land has been lived in continuously for more than 40,000 years.[2] The park’s rock art sites, many thousands of years old, show hunting, gathering and ceremonies.[2]
In central Australia, the Anangu people are the traditional owners of Uluru and Kata Tjuta.[3] They have lived in the area for tens of thousands of years.[3] Their law and spiritual beliefs, called Tjukurpa, link people, plants, animals and the land.[3] Today the Anangu and the Director of National Parks manage the park together.[3]
There are many different Aboriginal and Torres Strait Islander nations, each with its own languages, stories and traditions. Learning about them is an important part of understanding Australia.
The Great Barrier Reef
The Great Barrier Reef, off Australia’s northeast coast, is the world’s largest coral reef system.[4] It covers about 348,000 square kilometers and includes about 2,500 separate reefs and more than 900 islands.[4]
The reef is full of life. UNESCO counts about 400 kinds of coral, more than 1,500 kinds of fish, over 4,000 kinds of mollusks, such as clams and snails, and around 240 kinds of birds.[4] Corals are tiny animals that build hard skeletons, and over thousands of years those skeletons form reefs.
The Great Barrier Reef is a UNESCO World Heritage site.[4] Scientists watch its health closely, because warmer ocean water can harm corals. Students who study the reef learn how ocean ecosystems work and why they need protection.
Uluru and the outback
Much of central Australia is dry land called the outback. In the middle of it stands Uluru, a giant sandstone rock that rises more than 300 meters above the plains around it.[3] About 32 kilometers to the west is Kata Tjuta, a group of large rock domes.[3]
Uluru is sacred to the Anangu people, and its stories are part of Tjukurpa.[3] The park used to be called Uluru (Ayers Rock, Mount Olga) National Park, but it now uses the Anangu names.[3] It is a UNESCO World Heritage site for both its nature and its living culture.[3]
The outback can be very hot and dry, and towns there are often far apart. Most Australians live near the coasts, especially in the southeast, where the big cities are.
Wildlife and nature
Australia is famous for animals found nowhere else, such as kangaroos, koalas, wombats and platypuses. Its national parks protect many of them.
Kakadu National Park is Australia’s largest national park, at about 1.98 million hectares.[2] It protects more than a third of Australia’s bird species, and its wetlands are home to millions of waterbirds.[2]
At Shark Bay, in Western Australia, about 11,000 dugongs, gentle sea mammals that eat seagrass, live in the bay.[5] Shark Bay also has huge seagrass meadows and stromatolites, rock-like formations built by tiny living things.[5] UNESCO says stromatolites are among the oldest known forms of life.[5] Australia has many other natural World Heritage sites, from rainforests to islands.[7]
Cities and the Sydney Opera House
Canberra is the capital of Australia, and Sydney and Melbourne are its largest cities. Most Australians speak English, and many families speak other languages at home too, because people from all over the world have moved to Australia. With about 28 million people, Australia has far fewer people than the United States, even though it is almost as large.[1]
The Sydney Opera House, with its roofs shaped like sails, is one of the most recognizable buildings in the world. It was designed by the Danish architect Jørn Utzon, who was chosen in an international competition in 1957.[6] It opened in 1973 on a point of land in Sydney Harbour.[6] UNESCO calls it a great architectural work of the 20th century.[6]
Australia is in the Southern Hemisphere, so its seasons are the opposite of North America’s: summer starts in December. Students can explore Australia’s neighbors on our Oceania page.
