Where is the Great Barrier Reef located?

The Great Barrier Reef is located off the coast of Australia, making it the world's largest coral reef system. It stretches over 2,300 kilometers (approximately 1,400 miles) and comprises around 2,900 individual reefs and 900 islands. The biodiversity found in the Great Barrier Reef is immense, housing thousands of species of marine life, including fish, coral, and other organisms, making it a vital area for ecological research and conservation.

The other locations mentioned do not correspond to the geographic placement of the Great Barrier Reef. Hawaii is known for its own unique coral ecosystems, Japan has coral reefs in certain areas, and Mexico has beautiful coastlines and reefs, particularly in the Caribbean, but none of these locations contain the Great Barrier Reef, which is specifically an Australian natural wonder.
