Dive The Great Barrier Reef
Ticked off in February 2010
Drop beneath the surface of the largest coral reef system on Earth, among turtles, reef sharks and fish in every colour.
The adventure
Diving the Great Barrier Reef starts with a boat ride out from the Queensland coast, the water turning from green to a deep, startling blue as you reach the outer reef. Then you roll backwards off the side and the noise of the boat disappears. Below you are gardens of staghorn, brain and plate corals, with clouds of fish swirling around them.
Every dive brings something new. Green turtles glide past, reef sharks patrol the edges and giant clams sit open on the sand. Further north, the Ribbon Reefs are known for the Cod Hole, where huge potato cod swim right up to divers, and in June and July dwarf minke whales visit the same waters. Night dives reveal a completely different reef, as the corals feed and creatures you never saw by day come out to hunt.
It's the largest coral reef system on Earth: more than 2,900 individual reefs and 900 islands stretching over 2,300 kilometres down the Queensland coast, the biggest structure ever built by living things.
Why it’s epic
- The reef stretches more than 2,300 km and is made up of around 2,900 individual reefs.
- It has been a UNESCO World Heritage Site since 1981.
- Six of the world's seven species of marine turtle live on the reef.
- Mass coral spawning happens a few nights after a full moon in late spring, usually November or December.
What it is
The Great Barrier Reef is the world's largest coral reef system, stretching over 2,300 kilometres.
How to do it
Dive or snorkel from Cairns, Port Douglas or the Whitsundays on day boats or liveaboards to the outer reef.
