Diver's Notes

The wind was howling for this dive, but since it was directly out of the west the seas were flat with just wind spray and a slight chop. Cold as buggery whilst on the surface but fine once underwater. Dived westwards from the entry point of the rock ledge. Descended over the boilers to the sand line and kelp hoping to see the usually common Weedy Sea Dragons. Alas, there were none of this day. But there were numerous Port Jackson Sharks and Nudibranchs. As well as pair of gorgeous and curious cuttlefish. A Blue Groper followed us for the entire dive like a puppy dog. Would not leave us alone and tried to get between my camera and subject at any opportunity. Numerous pictures where photo-bombed by this Groper. Turned at about 120bar with due to some less experienced divers in the group, and surfaced right on the exit point.
