About The Diving

Australia is famous for the Great Barrier Reef in the Coral Sea. Stretching over 1400miles along the Queensland coast, it is one of the seven natural wonders of the world.  As the biggest reef on Earth, the GBR attracts divers from all over the world, who are rewarded with spectacular marine life and vibrant coral reef.  However, being surrounded by warm oceans, Australia’s massive coastline offers an incredible array of diving opportunities on the other coasts too. 

Below we’ll take a highlights tour around this epic continent starting with the GBR in Queensland, clockwise round the coast, finishing up with Australia’s Indian Ocean Territories.

Dive Highlights


The Great Barrier Reef is probably the most famous scuba diving destination in the world, covering over 1400 miles of ocean and over 2900 individual reefs. There is so much diving to be done here and this huge coral reef system has something for every diver.  Day trips can be taken from Cairns and Port Douglas. Liveaboards give the chance to reach sites further offshore.  

Whitsunday Islands

Accessed via the town of Airlie Beach, the Whitsunday Islands lie between the coast and the GBR. Topside they are covered in rainforest and white sand beaches while beneath the waves the water teems with tropical marine life, corals, and vibrantly coloured fish.

Ribbon Reef sees a congregation of dwarf minke whales from June to July and has nesting turtles.

SS Yongala, Townsville

In 1911 the 350ft passenger freighter SS Yongala sank off the coast of Eastern Australia near Townsville. Today it is one of the most spectacular wreck dives, with the wreck still very much intact and incredible life including giant groupers, turtles, whales, sea snakes, manta rays and barracuda. As an official grave site, it is forbidden to enter the wreck, but some great dives can be had appreciating the wreck from the outside and enjoying the myriad of life it attracts. Some strong currents at depth make this dive more suited to experienced divers.
