March and April are the best times to dive the mid north coast. The weather
and the waters are still warm and seas are settled which means optimum
visibility. Six members of the Great Lakes Underwater Group (GLUG) left
the jetty with the sun shining and the bar reasonably calm.
At The Graveyard site each took a giant stride off the boat into clear warm
water. Peter Trood, Heather Armour and Janne and Tony Moran, to perform
transects for two areas whilst Anita and Greg Toland were to do Spot a
Shark monitoring using cameras with laser beams. The tapes were to a rock
and ran the obligatory 25 metres in a straight line, then the divers slowly
swam back along to monitor for marine debris. An old anchor with a chain
was found on the first transect but nothing in the opposite direction so
random searches were commenced. Later a fishing rod and a fishing lure
was found amongst the kelp. Also spotted were a large numb ray and a Port
Jackson Shark but no grey nurse sharks. Total dive time was 46 minutes
with a maximum depth of 17.8 metres.

After a surface interval the boat motored over to the second site, Charlottes
Reef just off Shelly Beach. The water was shallower this dive so a slight
current was evident and the visibility was down. Again transects were taken
with no marine debris found. After a short time however near the rocks
fishing line, sinkers, hooks, rope and plastic netting were retrieved as well
as a surfboard fin. A large anchor with chain was sighted but could not be
retrieved so several photographs were taken. Several house bricks were also
sighted. Three more numb rays were lying amongst the rocks. Total dive
time was 52 minutes with a maximum depth of 9.8 metres.
Water temperature was 21 degrees.
