Overview

The Great Barrier Reef extends for about 2,300 km off the coast of Queensland and is made up of thousands of individual reefs and hundreds of islands. It has been a UNESCO World Heritage Site since 1981.

It is home to corals, fish, turtles, rays and, in season, whales. Visitors explore it by boat from towns such as Cairns, Port Douglas and Airlie Beach, or from island resorts.

Best time to visit

June to October is drier and milder, with good visibility. November to May is hotter and wetter; marine stingers are present near the coast in roughly those months, so wear a stinger suit where advised.
