Scuba Diving Port Douglas

Let the diving begin. Meet the locals! - Potato Cod, Moray Eels,Napoleon Wrasse, Coral Trout, Nudibranchs and Giant Clams. Enjoy the biodiversity of the Great Barrier Reef Marine Park

The Wreck

Depth : 22 meters Visibility : 20 meters

Almost eighty years ago a Taiwanese fishing boat ran aground at the outer edge of Agincourt reef and subsequently sank to the ocean floor. Today the wreckage remains where it came to lay and makes for an interesting dive. Plenty of fish now inhabit the wreck site and divers can expect to see Fusiliers, Clown Fish, Sweetlips, and a few Green Turtles.

Castle Rock

Depth : 24 meters Visibility : 15 metres

Located at the southern end of Agincourt Reef, the Castle Rock dive site is known for its excellent visibility and abundance of fish. Some of the resident fish here even have names and like to swim over for a pet in the hope you have brought some tasty morsels. Axle is a 1.2 metre Malabar Cod, Daisy is a flowery Cod and another well known resident is Wally the Maori Wrasse.

Other Giant Cods, Triggerfish, Blue Lined Yellow Snappers, Sergeant Major Damsel Fish, Parrotfish, Wrasse, and Blue-Green Chromis are some of the species you can expect to see darting through the coral at Castle Rock. There is also a good chance that you will encounter a White-Tip Reef Shark or two resting on the sandy ocean floor, or some interesting looking Christmas Tree Worms residing on the coral.

Nursery Bommie

Depth : 24 meters Visibility : 20 meters

An underwater photographers dream, Nursery Bommie is one of Agincourt Reefs top spots to dive. Brimming with aquatic life and excellent visibility conditions, this site is home to schools of Picklehandle Barracuda, White and Black-Tip Sharks, Moray Eels, Clown Fish, and plenty or brightly coloured coral. Nursery Bommie is a real favourite for professional divers due to the clarity of the waters and the abundance of variety of marine life and corals.

Turtle Bay

Depth : 22 meters Visibility : 20 meters

Like the name suggests, at this dive site you are bound to see some turtles. From October - December large Loggerhead Turtles visit the area. Visibility is always great, spectacular Sea Cucumbers, Parrotfish, Red Bass, and giant Clams can be seen year round. During the spring (September-November) and around the new moons this reef wall is a spawning site for a wide range of fish species "sex on the reef".

Giant clam shells are common here as are Steep head Parrot fish and when you encounter the deep drop off zones you may also encounter the Grey Reef Shark but don't worry they shouldn't bite.

The Three Sisters

Depth: 20 metres Visibility: 10-30 metres

This reef was named as such due to the presence of three deep pinnacles located on the sheltered side of a patch reef located on the inner edge of Agincourt reef. This is an excellent site to find Butterfly fish, colourful Wrasse, Parrot fish and giant mature clams in the shallower waters

Barracuda Bommie

Depth : 22 meters Visibility : 20 metres

Visibility is always excellent at Barracuda Bommie which is one of the outer most dive spots on the Great Barrier Reef. Dog Tooth Tuna, Coral Shrimps, Feather Starfish, Christmas Worms, and the very interesting Nudibranchs inhabit the area. When diving at Barracuda Bommie, Nudibranchs will be hard to miss. They are most often brightly coloured yet have the same body shape as a Sea Cucumber. The curious creatures are certainly a sight to behold. This is one of the most favourite diving and snorkelling spots.

Triggerfish City

Depth : 16 meters Visibility : 15 meters

An abundance of caves and large rocks play home to thousands of Titan Triggerfish, Red Bass, Clown Fish, and Oriental and Striped Sweetlips. The very rare Pipefish has been spotted at this dive spot, so keep your eyes peeled for the straight bodied seahorse looking creatures as getting to see one would be a once in a life time opportunity.

The Gardens

Depth : 10 meters Visibility : 20 meters

This shallow dive site is home to Parrotfish, Butterflyfish, Goatfish, Milkfish, and giant Maori Wrasse. The coral gardens at this site are simply stunning and watching an abundance of fish frolic and forage amongst the bright coral makes for an excellent dive.

Harrys Bommie

Depth : 16 meters Visibility: 10-30 metres

A stunning garden reef with two dive locations one on the northern side of the Reef which protects you from the south easterly winds and the second is to circumnavigate the patch Reef as this reef is split in two with a narrow gap that is current prone. Some of the locals and visitors to Harrys Bommie are groups of groups of Grey Reef Whalers, Manta Rays, Coral Trout, Groupers and White Tip Reef Sharks.

These are but a few of the best dive and snorkel spots that the Agincourt Ribbon Reef area on the Great Barrier Reef has to offer and as you can see each dive and snorkel site offers something new and unique to the visitor. Every different coral structure hosts different species of fish and marine animals and that's why we always recommend that as a visitor you should visit the Great Barrier Reef not only once but as often as possible as every trip out to the reef will be different.
