The Great Barrier Reef is the world's largest organic structure, making it one of the seven natural wonders of the world. Almost one fifth of the world's coral reefs could be found here. Over 400 varieties of corals are seen in the Great Barrier Reef. It also houses an estimate of 1,500 different kinds of fish and almost 4,000 types of mollusks. Tourists would be amazed to take a glimpse of these wonderful creations. Another popular tourist destination is the world-famous Sydney Opera House.
