Great Barrier Reef

The world's largest coral reef system, the Great Barrier Reef is home to thousands of species, stretching over 1,800 miles (3,000km) from the coastal town of Bundaberg up to the tip of Cape York, almost parallel to the Queensland coast. It is not until Cape Tribulation, just north of Port Douglas that the reefs come right to the shore and meet the tropical rainforests of the Wet Tropics. The breathtakingly beautiful coral stretches further than the Great Wall of China and is the only living thing on earth visible from space.

The varied colours of the reef's fish and other marine life will astound you with colour combinations you couldn't imagine. The reef is widely considered one of the great wonders of the world. The World-Heritage-listed marine park supports the greatest concentration of life with over 1,500 species of fish, 400 different corals, 4,000 species of molluscs and 10,000 species of sponges. Six of the world's seven species of sea turtles are found here and whales are often encountered in these waters.
