Admiralty Islands Dive Sites

The Admiralty Islands are located to the north of Lord Howe Island approximately 15 minutes by boat from the Pro Dive Lord Howe Island office.  This group of volcanic formations are home to over 30 dive sites with a variety of terrain from large pinnacles and boulders to coral walls and caves. The Admiralty group is a must while on Lord Howe island as here you will find large schools of fish, rare as we'll as endemic species, beautiful soft and hard corals, crystal clear water and depths from 15 - 40 metres.


Named after the Brown Noddy Turns that rest on top, the island drops into the water to a depth of 20 metres. The walls are covered in anemones, coral, sponges and weed. There is also a beautiful reef in the channel just away from the island itself. This site is perfect for multi-levelled diving for those who wish to extend their bottom time as the shallower sections of the walls also hold various points of interest.  

What to look out for:

Common Species- Mosaic Moray, Freckled Porcupine fish, Japanese Boar fish.

Rare and interesting Species- High Tailed Shrimp, Wide-Barred Clownfish on fluorescent anemones and Elegant Wrasse.


Named after one of Lord Howe’s original local divers who pioneered diving on the island. Boat anchors in 8 metres in the channel between No-Name Rock and Roach Island. The dive begins in the middle of the reef and you swim through a large crevice. This will bring you to the deepest part of the dive in a depth of 22 metres.The dive can then be completed by swimming around the edge of the reef, back towards the boat and into shallower water. Spot the resident Green Turtle. There are lots of small sea fans, purple and orange bryozoans. Small squat lobsters and grey coral gobies in the hard corals if you have keen eyesight. Saddled Rock Cod, and occasionally large Painted Crayfish.


Series of alcoves that cut into the island. Beautiful Dendronephthya soft corals. Large schools of Silver Drummer, Kingfish and occasionally huge schools of Eastern Garfish. Depth ranges from 5 - 16 metres.The rare Flame Hawkefish has been spotted by one observant local diver. Large solitary kingies are often seen here as are two Black Cod, one probably in excess of 50 kilos. Rare/Interesting Species- Flagtail Blanquillo, Mustard Shrimp.


Vertical pinnacle of reef rising from 18 - 7 metres. This site can be circumnavigated quiet easily, allowing time to proceed over to the boulders near the island. A must do dive at the Admiralty Islands. Spanish Dancer haven, Blue Angelfish, Green Jobfish, and Japanese Boarfish are some of the rare species that are regularly seen here. Look for Tricolour Basselets and Round-Backed Coral Crabs on top of the pinnacle.


Large plateau reef in 20 metres with cracks running through it. This reef drops 10 metres to the seafloor in a wall of soft corals, gorgonians and black coral trees. Follow this wall along in 30 metres and pass through huge canyons, tunnels and swim throughs. A reliable place to see huge Black Cod, Harlequin Tuskfish (with its blue teeth) and Long Nosed Butterflyfish.


Spectacular site that can be dived from 12 - 24 metres. Fish life when the current is running is staggering with Kingfish, Big-Eyed Trevally, Unicornfish, Surgeonfish, Knifefish and Rainbow Runners. Don’t forget to keep your eyes on the reef wall as you may spy Great Barrier Reef Anemone fish, rare Nudibranchs such as the Elegant Tritoniopsis, and Christmas Tree Black Corals.

NORTH ROCK (North Rock Close and North Rock Deep)

Depth 18 - 35 metres

This site can be done separately or together, depending on the swell and current. One of Lord Howe Islands premier dives.

To dive here is an exceptional and lucky experience. Very exposed and prone to strong currents, both these factors lead to great fish-life, soft coral growth and large black coral trees. Descend down the anchor line at North Rock Close into a large ampitheatre next to a coral pinnacle and be surrounded by schools of Southern Fusiliers, Violet Sweep and Trevally. Swim to the south to North Rock Deep past Spangled Emperors, curious Amberjack and cute Clown Triggerfish.

North Rock Deep starts at a raised reef that you can go over, past bright purple and pink soft corals or for those in the know the reef can be navigated via a series of tunnels and swim throughs that split the reef. If you don't come face to face with a 2 metre Black Cod the swim throughs will bring you to a bowl shaped reef that grows yellow soft corals and houses schools of Yellow Striped Goatfish, immense Kingfish and Galapagos Whaler Sharks. Once over the lip of the bowl, if you go a bit further to a twin pair of Black-Coral Trees there is a school of Tri-Coloured Basselets that numbers upward of 50.
