Great Barrier Reef Scuba Diving

Australia is known for its unusual animals, rich marine life, fascinating culture, Crocodile Dundee, Vegemite and very distinctive accents.

When it comes to below the ocean's surface, one particular part of Australia's marine heritage stands out above all others; the Great Barrier Reef and here is the best place to find your choice of Australian Liveaboards. Rated as Australia's, and one of the world's, top dive destinations, the Great Barrier Reef should be at the top of any true dive enthusiasts' must-do list of places to visit.

Stretching over 2,000km from Lizard Island in the north down to Great Palm Island in the south, the Great Barrier Reef is the world's largest coral reef system and the only such structure, made up of living organisms, actually visible from space.

The main attractions being the dizzying array of marine life it supports, many of which are believed to be endemic to the Great Barrier Reef showcasing the best of Australia scuba diving.

A more specific attraction of the reef is that it's the breeding ground for 6 species of turtle, attracted by varied menu of seagrass. The olive ridley, hawksbill, leather back, green, flatback and loggerhead turtle are all frequently spotted at various sites on the reef.

The reef is also a veritable playground for dolphins, whales and porpoises, including humpback whales, minke whales and Indo-Pacific humpback dolphins. Around 30 species have been recorded on the Great Barrier Reef. Dugongs are also commonly spotted.

Of sharks the reef has no shortage, with 125 recorded species of shark, stingray or chimera lurking about the reef or on the sandy bottoms, at home amongst the reefs endless offering of choice tidbits.

More than 400 species of soft and hard coral smother the region. An annual mass spawning takes place when the corals of the inner reefs spawn in the week after the October full moon and the outer reefs do the same in November and December.

Molluscs, giant clams, nudibranchs, cone snails, pipefish and seahorses, all have multiple species hidden amongst the coral's nooks and crannies, providing colour and life to a reef too expansive for to ever explore in its entirety in a single lifetime.

The corals of the Great Barrier Reef harbour over 1,500 species of fish, including clownfish, red-throat emperor, red bass, several species of snapper and coral trout, lionfish, stonefish and many more.

In a demonstration of marine diversity, even saltwater crocodiles have a connection to the reef. Luckily they are restricted to marshes and mangroves on the coast near the reef.

How to Dive Australia

Great Barrier Reef liveaboards are the best way to make the most of your diving trip to Australia.

Dive The World offers you access to the Outer Barrier Reef with day-trips, or more often short liveaboards to maximise your number of dives.

Due to the distance to the Ribbon Reefs and the North Coral Sea, they are accessible through liveaboard cruises only, and is your key to the splendour that can only be found on these distant parts of the Great Barrier Reef.

The Inner Barrier Reef consists of shallow reefs accessible through shore dives from the islands or day trips. We do not offer this destination since the quality of the diving is not as high as elsewhere on the Great Barrier Reef.

Diving Season

Australia as a whole is a year round dive destination but, for most part, late August to early December yields the best diving conditions.

The best time for an Australia liveaboard is July to November, although in the Coral Sea at Osprey Reef and North Horn, visibility peaks during June and September.

Minke Whale season around the Great Barrier Reef is usually from June to August and is the ideal time to spot and interact with these gentle giants.
