Some years ago Pictus shell was dived by shell collectors off this reef at night. A fairly flattish reef with sections where the sand washed away, leaving holes for catfish and other reef fish to hide. The brittle stars on this reef are definately on some form of steriods as they measure about 30cm wide, sitting on big ferns in the surge. At a depth of 18 to 22m deep and only 4km from the launch site. Big swell can influence the viz as there is lots of sand in between the reef.
