Which continent is famous for the Great Barrier Reef?

The Great Barrier Reef is renowned as the largest coral reef system in the world and is located off the coast of Australia. Spanning over 2,300 kilometers, it is made up of thousands of individual reefs and islands, making it a UNESCO World Heritage Site and a significant destination for biodiversity, tourism, and marine research. The reef's vibrant ecosystems are home to a vast array of marine life, including fish, corals, and other aquatic organisms, which thrive in the warm, shallow waters of the Coral Sea.

Australia is uniquely positioned with its extensive coastline and favorable environmental conditions that contribute to the health and diversity of the reef. This makes it a key geographical feature not found in the other continents listed. The other options do not have comparable coral reef systems of this scale, highlighting Australia as the distinct choice associated with the Great Barrier Reef.
