Great Barrier Reef

The only living thing on Earth that can be seen from space, the Great Barrier Reef is immense. Located in northeastern Australia off the coast of Queensland, this 2,300-km-long complex ecosystem comprises more than 3,000 individual reef systems, coral cays, and hundreds of islands, big and small, with sparkling white sandy beaches. 

The 2,300km-long ecosystem comprises thousands of reefs and hundreds of islands made of over 600 types of hard and soft coral. It's home to countless species of colourful fish, molluscs and starfish, plus turtles, dolphins and sharks.

 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 Great Barrier Reef is breathtaking to behold – and so is its size and scope. A vast interplay of ecosystems and their inhabitants, the reef is home to around 600 types of hard and soft corals. Hard corals form the ‘backbone’ of the reef, providing a living home for a huge range of marine animals, from fish and molluscs to plankton and algae.
