What You'll Learn
The Great Barrier Reef spans over 2,000km in length
The Great Barrier Reef is a natural wonder and one of the world's largest living structures, stretching over 2,000 kilometres off the northeastern coast of Australia. It is a complex ecosystem of coral reefs, islands, and other formations, teeming with diverse marine life.
The reef's vast expanse covers approximately 350,000 square kilometres, an area roughly the size of Japan or Italy. It extends from the Torres Strait in the north, between Bramble Cay and the south coast of Papua New Guinea, to Lady Elliot Island in the south, with its offshore distance ranging from 16 to 160 kilometres. The width of the reef varies from 60 to 250 kilometres.
The Great Barrier Reef is not just a single entity but a collection of thousands of individual reefs, islands, and coral cays. It is estimated to consist of 2,900 individual reefs and 900 islands and coral cays, providing a habitat for an incredible array of marine plants and animals. This includes more than 1,500 species of fish, about 400 species of coral, 4,000 species of molluscs, and 240 species of birds, as well as sponges, anemones, marine worms, crustaceans, and many other organisms.
The reef's formation began millions of years ago, influenced by tectonic activity and sea level changes. As Queensland drifted into tropical waters, coral reefs began to grow, and over time, the Great Barrier Reef took shape. Today, reefs can increase in diameter by 1 to 3 centimetres per year and grow vertically by anywhere from 1 to 25 centimetres per year.
The Great Barrier Reef is not just a natural wonder but also holds cultural and spiritual significance for Indigenous Australians, who have a deep connection to this unique marine environment. It is a popular tourist destination, attracting visitors from all over the world eager to explore its beauty and diversity, generating significant economic revenue for the region.

It covers an area of 344,400 square kilometres
The Great Barrier Reef is a natural wonder and the largest living structure on Earth. It is so large that it can be seen from space. Located off the coast of Queensland, Australia, in the Pacific Ocean, the Great Barrier Reef covers an area of 344,400 square kilometres. This is roughly the size of Japan or Italy.
The Great Barrier Reef is a complex ecosystem of hard and soft coral. It is made up of thousands of islands and reefs that stretch from the tip of Queensland at Cape York to Bundaberg in the south. The reef reaches from the Torres Strait in the north to Lady Elliot Island in the south. Certain stretches come as close as 15km offshore, while other areas are hundreds of kilometres from the mainland.
The Great Barrier Reef is a site of remarkable variety and beauty. It is home to the world's largest collection of coral reefs, with 400 types of coral, 1,500 species of fish, and 4,000 types of mollusc. It also holds great scientific interest as the habitat of species such as the dugong ('sea cow') and the large green turtle, which are threatened with extinction.
The Great Barrier Reef is a popular destination for tourists, especially in the Whitsunday Islands and Cairns regions. It offers an abundance of coastal experiences, including scuba diving and snorkelling among stunning coral formations, giant clams, rare species of whales, and six of the world's seven marine turtle species. The reef is also of great cultural significance to Indigenous Australians, who have lived on and alongside it for thousands of years.

The reef is made up of 3,000 individual reef systems
The Great Barrier Reef is a natural wonder and the largest living structure on Earth. It is so large that it can be seen from space! The reef is not a single entity but a vast collection of thousands of individual reefs, islands, and coral cays. It is made up of 3,000 individual reef systems, 760 fringing reefs, 900 tropical islands, and about 300 coral cays. These coral cays include the famous Green Island, a popular destination near Cairns known for its rainforest and beautiful fringing reefs.
The Great Barrier Reef is located in the Coral Sea on Australia's East Coast, stretching from the tip of Queensland at Cape York in the north to Bundaberg in the south. It reaches a distance of over 2,000 kilometres (1,250 miles) in a northwest-southeast direction, with a width ranging from 60 to 250 kilometres (37 to 155 miles). The reef is an important part of the culture and spirituality of Aboriginal Australian and Torres Strait Islander peoples, with 70 Traditional Custodian groups whose Sea Country includes the Great Barrier Reef Marine Park.
The Great Barrier Reef is a complex and diverse ecosystem, home to a staggering array of marine life. It contains the world's largest collection of coral reefs, with around 400 types of coral, over 1,500 species of fish, and about 4,000 types of molluscs. It also provides a habitat for threatened species such as the dugong and the large green turtle. The reef is a popular destination for tourists, offering scuba diving and snorkelling experiences to explore its vibrant marine life.
The reef's formation began millions of years ago, influenced by tectonic activity and volcanic eruptions. Over time, coral reefs began to grow in the Coral Sea Basin, and as Queensland drifted into tropical waters, the Great Barrier Reef as we know it today began to take shape. The reef's growth is a slow process, with reefs increasing in diameter by 1 to 3 centimetres per year and growing vertically by anywhere from 1 to 25 centimetres annually.

The Great Barrier Reef is the largest living structure on Earth
The Great Barrier Reef is made up of thousands of individual reefs, coral cays, and islands. It is estimated to be 500,000 years old, but the reef as we know it today began taking shape 8,000 years ago after the last ice age. As the climate warmed and the ice melted, sea levels rose, flooding the continental shelves off the coast of Australia. Tiny soft-bodied organisms called coral polyps started building on ancient reefs and volcanic islands, and over time, they formed the Great Barrier Reef.
The Great Barrier Reef is the world's largest and most complex coral reef ecosystem, attracting hundreds of thousands of visitors annually. It is one of the world's seven natural wonders and a prized UNESCO World Heritage Area. The reef is home to an incredible array of marine plants and animals and is one of the most biodiverse ecosystems on the planet. It is also one of the few living structures visible from space, appearing as a complex string of reefal structures along Australia's northeast coast.
The Great Barrier Reef is of great scientific interest as it is home to species that are threatened with extinction, such as the dugong ('sea cow') and the large green turtle. It is also an important part of the culture and spirituality of local Aboriginal Australian and Torres Strait Islander groups. The reef is a very popular destination for tourists, especially in the Whitsunday Islands and Cairns regions, and tourism is an important economic activity for the region, generating over AUD$3 billion per year.
The Great Barrier Reef is facing significant threats due to coastal development, pollution, and human interference, which are disrupting wildlife and destroying habitats. It has also suffered multiple mass coral bleaching events as a result of warming ocean temperatures caused by climate change. Efforts are being made to bolster the resilience of the reef, and the Australian Institute of Marine Science conducts annual surveys of the Great Barrier Reef's status.
