The Earth's largest structure made by living organisms is one of the major reasons travelers head Down Under. With sections dating back 18 million years, the incredible 135,000-square-mile Great Barrier Reef is made up of 3,000 individual reefs and islands, and it hosts more than 400 species of coral along with 1,500 species of fish. The reef stretches most of the length of Australia's tropical northeastern state of Queensland.
