Why Dive in QLD

About Diving in Queensland and the Great Barrier Reef

With warm, clear waters, teeming with marine life, spectacular shipwrecks and the world’s largest coral reef, Queensland is a scuba divers paradise.

The Great Barrier Reef

The Great Barrier Reef stretches through Queensland’s waters for more than 2,500 kilometres, covering around 345,000 square kilometres. The world’s largest World Heritage site is made up of more than 2,900 individual reefs, and 70 coral cays scattered along the edge of the continental shelf.

Queensland’s Great Barrier Reef is the world’s most extensive coral reef system, which together with sea grass, mangrove, and soft bottom and island habitats; enable the park to showcase the richest collection of faunal diversity in the world.

Diving into the Great Barrier Reef will introduce you to an underwater world filled with thousands of brightly coloured species of marine life. Some 1,500 types of fish, 4,000 types of molluscs, 350 types of echinoderms and 350 types of coral, attract divers from around the world each year.

Explore vast underwater gardens and forests, as graceful turtles and manta rays soar overhead. Come face to face with gentle giant Potato Cod and Queensland Groupers, which are larger than life and experience the most stunning wall diving.

Wreck Diving

The cooler subtropical waters of Southern Queensland offer a myriad of different experiences to those of the tropical waters in the north. World-class wreck dives, reefs and vast rock walls boast abundant marine life, with turtles, rays, wobbegongs, nudibranchs and large schools offish populating the various dive sites along the South Queensland coast.

Hundreds of shipwrecks are dotted along Queensland’s coast, more than any other state in Australia. Covered with coral and teeming with marine life, they’re a scuba divers theme park. Among world-class shipwreck dive sites in Queensland you’ll find the SS Yongala, near Townsville, the RMS Quetta, off Mt. Adolphus Island, just northeast of Cape York and the Ex HMAS Brisbane located off the Sunshine Coast, north of Brisbane.

Night Diving

The adventure of a night dive reveals the stars of the reef-colourful new corals and radiant glowing fish. As the full moon sets in October/November, witness the technicolour snowstorm of coral polyp spawning – an unforgettable experience.


Of course, you don’t have to be a diver to witness the beauty of Queensland’s Great Barrier Reef! Numerous day tours and Liveaboards cater for the non-diver, offering options including snorkelling, underwater viewing platforms and glass bottom boats.


From June to September, the Minke and Humpback whales migrate up and down the Queensland coast.

Coral Spawning

Each year sometime around late October or November a synchronised coral spawning takes place on the Great Barrier Reef. If you’re lucky enough to be visiting during this time, it is quite a spectacular event that attracts scuba divers and snorkelers from across the globe. As coral spawning is linked to the moon and water temperatures, it’s hard to predict exactly when this mass reproduction will happen.  Coral spawning on the Great Barrier Reef involves colonies and species of coral polyps simultaneously releasing tiny egg and sperm bundles from their gut cavity into the water. 2016’s coral spawn started around 16 November and lasted for four days.
