South West Rocks, New South Wales
Big Fishes Reef Sharks Wall
Green Island is situated just north of Smoky Cape Lighthouse (south of Gap Beach in Hat Head National Park) and can easily be seen from the Lighthouse car park looking north. The island is only a little way off the shoreline - unfortunately difficult access from the mainland means the dive site is only accessible by boat!
The most popular part of Green Island for diving is the northern and eastern sides as this is where the overhangs, ledges encrusted with colourful sponges and rocky reef provide a protective habitat for a wide variety of marine creatures. Edged by sand the reef hugs the island as you swim or drift south (see below). Explore the boulders where cuttlefish, blind sharks and wobbegong sharks lie, check out the overhangs where you may find a resting loggerhead or green turtle (residents here), large black sting (bull) ray or very large wobbie. It's recommended taking a torch as there are so many critters hiding in the walls or in the boulders - juvenile lionfish, myriad varieties of nudibranch, moray eels, tiny yellow box fish.
But don't forget to look up and around as sometimes you can see large shovel nose sharks/rays out on the sand and spotted eagle rays flying overhead (these are often also seen right on the southern tip of the island where the wall of the island becomes more sheer and there are two very narrow gutters). Green Island is also known for its fish: large schools of colourful tropicals and temperates. You are more than likely to see small fiddler rays especially on the sand edge of the reef, plus dusky flathead, bream, yellowtail, southern fusiliers, leatherjackets, wrasses (especially the very friendly large eastern blue wrasse or blue grouper), luderick and morwongs. Also look out for the schooling benito, jew fish and king fish plus of course the Grey Nurse Sharks.
Since 1 December 2002 Green Island is (in addition to Fish Rock) a Critical Habitat for Grey Nurse Sharks which will hopefully assist in the protection of these magnificent but threatened creatures. However even without spotting one of these creatures Green Island is an amazing place.
Green Island is excellent alternative to the dives at Fish Rock, and is often requested by regular divers - dive it and you'll see why! If you spend a surface interval here do keep an eye out for the majestic eagles that use Green Island as a resting place and/or look out over the ocean.
Average depth 14 metres though varying between 6 metres (northern end) and 18 metres (southern end)Easy Drift around the island, plenty of grey nurse, turtles as well as the small stuff
