Australia is known for the Great Barrier Reef, which stands as one of the most significant and iconic natural features of the country. Spanning approximately 2,300 kilometers along the northeast coast of Australia, the Great Barrier Reef is the world's largest coral reef system. It comprises over 2,900 individual reefs and 900 islands, housing a rich diversity of marine life, making it a UNESCO World Heritage site and a major attraction for tourism.

The Great Barrier Reef is unique not only for its size but also for its ecological importance and its contributions to biodiversity. It provides numerous habitats for various species, supports local fisheries, and plays an essential role in the environmental health of the region. Because of its beauty and biological significance, it has become a symbol of Australia's natural heritage, attracting millions of visitors each year who seek to experience its vibrant underwater ecosystem.

The Rocky Mountains are located in North America, the Amazon Rainforest is found in South America, and the Sahara Desert is in North Africa. These do not represent the unique natural landscape that Australia is renowned for.
