Comments :
Surface swam out to motorbike wreck and descended. Then crossed over to the rock wall and set out around the point following the sand line and boulders. Went further around the point than i have been on any previous dives at this spot.
The rock wall gave way to kelp bed and smaller rocks and then the rocks became larger, flatter and absent of sea grasses or kelp.
The water was crystal clear from the beach but vis reduced considerably the further we went into open water and around the point. Abundant floating particles produced lots of backscatter in the photos. Vis was 15m at the start but dropped to 10 and then at times 5m.
Dominant feature of the dive was leather jackets of many different species - i counted 5 different types, generally in pairs. There was also large schools of one-spot pullers and several wobegongs and port jackson sharks.
Turned at 110 bar to leave enough for the return as the current was increasing and becoming moderately strong. Followed boulders and sandline back to the rock wall and then along the rock wall all the way back to shore at Shelly beach. A long dive of over an hour.
