The northern and eastern sides of Pig Island are very good. Here the reef drops to sand at 24 metres or more and is composed of a rocky bottom with the occasional large boulder. A very good reef dive. The southern end of the island is also worth visiting.

One very good spot is off the south eastern corner of the island. The best spot to launch your own boat is the Port Kembla boat ramp, located in the Outer Harbour, behind BHP. Head out to Pig Island and go to the southern end. Start heading up the eastern side, about 30 or 40 metres off the island, and using your depth sounder, drop anchor when the depth comes up from 25 metres to about 18 metres. A good spot to anchor is 34° 28' 04"E 150° 56' 41"S (note that all my GPS Readings are using AUS66 - if you use any other datum, you will need to convert the reading - see my GPS Page for more details).

The reef runs to the north-east at first and then turns more north. Follow the bottom of the small wall to the north and return along the top, just below the kelp line. There are huge numbers of sponges, sea tulips and gorgonias all along the way. There are also more lace corals than I have ever seen in one location.

To the west of the anchor there are normally huge schools of ladder-finned pomfret, nannygai and silver sweep. The fishlife is excellent, with lots of trevally and yellowtail blanketing the area with numerous friendly blue groper and combfish. Moray eels, huge rays, wobbegong sharks and giant cuttlefish are also seen regularly.

In summary, a very good dive site. You can dive here using United Diver who run from Wollongong Harbour. I recommend Leon's service as been up there with the best in NSW.
