Explore the Great Barrier Reef
See the wonders of the Great Barrier Reef, home to 1625 fish species and 450-plus types of coral, as well as marine turtles, starfish, dugongs, sea anemones, crustaceans, sponges and shells. An unusual underwater experience is available at Green Island near Cairns. Seawalker helmet-diving involves walking along the sea floor close to a coral reef. The waterproof helmet allows those with glasses and contact lenses to keep wearing them for a better view of the reef animals. Coral spawning occurs on Australia’s east and west coasts at different times of the year. On the Great Barrier Reef, the spectacular annual event takes place in late spring or early summer (October-December) while on the west coast it happens on Ningaloo Reef, near Exmouth, in autumn (March-April).
