March - After 3 La Ninas the current El Nino has been the wettest I have seen here.
Unfortunately the river is badly affected and is still not worth a dive. I have also
not been able to dive at Hastings Point since before the Christmas holidays. Nothing
on the beaches as well.

November - not a lot of opportunity to get in the water lately. A search of the
mangroves revealed large numbers of the seaslug Elysia bangtawaensis in
mudcrab holes and shallow natural drains.

of rain. A few calm, clear days at Hastings Point were very rewarding, with
some new species. Some name changes as well.

April - Finally the seasons have changed after the hottest March on record. Still no diving
in the river. A couple of visits to Hastings Point but conditions weren't the best, with a lot
of surge and bubbles.

February - More Ascideans and two interesting chitons, also new images of Madrella sanguinea.
Only a couple of trips to Hastings Point over the last months because of heavy crowds
during the school holidays. Kids are now back at school so I hope to get some more diving done.
Quite a few unidentified species so any help would be greatly appreciated.

November - A third consecutive La Nina has been confirmed, more rain, more floods. Strong prevailing
north winds make conditions difficult at Hastings Point.

September - Only a few finds on the beach, and still no diving. Spring is here so hopefully I can get back into the
water at Hastings Point as the river here is still not worth a dive. The forecast of another La Nina is not encouraging

May - Still no diving as rain periods since the floods have kept the water dirty. Continuing onshore winds that
normally provide interesting beach finds are producing nothing, so no new images. Not a great year so far. I have
added a couple of old finds that I had not previously included, and spent a lot of time on the net in an effort
to put ID's on some species, even attempting to name a few Crinoids. Thank you to Audrey Falconer, and the Marine
Research Group of Victoria, who have uploaded files on South East Australian species. These have been very helpful
as some of these species extend to this area. www.facebook.com/groups/294926707198638/files
