The Great Barrier Reef is one of the seven wonders of the natural world, and pulling away from it, and viewing it from a greater distance, you can understand why. It is larger than the Great Wall of China and the only living thing on earth visible from space.

The marine park stretches over 3000km (1800 miles) almost parallel to the Queensland coast, from near the southern coastal town of Bundaberg, up past the northern tip of Cape York.

The reef, between 15 kilometres and 150 kilometres off shore and around 65 Km wide in some parts, is a gathering of brilliant, vivid coral providing divers with the most spectacular underwater experience imaginable.

A closer encounter with the Great Barrier Reef’s impressive coral gardens reveals many astounding underwater attractions including the world’s largest collection of corals (in fact, more than 400 different kinds of coral), coral sponges, molluscs, rays, dolphins, over 1500 species of tropical fish, more than 200 types of birds, around 20 types of reptiles including sea turtles and giant clams over 120 years old.

The reef is a breeding area for humpback whales, migrating from the Antarctic and is also the habitat of a few endangered species including the Dugong (Sea Cow) and large Green Sea Turtle. In recognition of its significance, UNESCO listed the Great Barrier Reef as a World Heritage Site in 1981.

Because of its natural beauty, both below and above the water’s surface, the reef has become one of the worlds most sought after tourist destinations.

In 2006 there were approximately 820 operators and 1500 vessels and aircraft permitted to operate in the Great Barrier Reef Marine Park providing ease of access for all to experience the Great Barrier Reef and learn first hand about its natural delights and World Heritage values.

Tourism

Due to its vast biodiversity, warm clear waters and accessibility from the tourist boats called "live aboards", the reef is a very popular destination, especially for scuba divers. Tourism on the Great Barrier Reef is concentrated in Cairns and also The Whitsundays due to their accessibility. These areas make up 7%–8% of the Park's area. The Whitsundays and Cairns have their own Plans of Management.Many cities along the Queensland coast offer daily boat trips. Several continental and coral cay islands are now resorts, including Green Island and Lady Elliot Island. As of 1996, 27 islands on the Great Barrier Reef supported resorts.

In 1996, most of the tourism in the region was domestically generated and the most popular visiting times were during the Australian winter.
