Species List: Shelly & Nudi Retreat, Sunshine Coast, Queensland, 26-06-2016

24 species sighted at two sites off Currimundi, Sunshine Coast Queensland.

Gary and Julie on the first dive of 87 minutes, 10 m viz., at Shelly, a small reef out from Ann Street, Dicky Beach on the Sunshine Coast. Terry acted as surface watch for this one because of a minor gear failure. Although the fish life was interesting, some large sweetlips and cod, the nudibranchs were few and far between so a decision was made to have the second dive at Nudi Retreat, Currimundi Reef.

Gary, Julie and Terry on the second dive of 74 minutes, 15 m viz, at Nudi Retreat. The surge here made finding critters difficult so the tally of 24 species over the two dives is quite respectable. It was nice to find the Hallaxa translucens, a species we do not get to see very often.

Species List: ex-HMAS Brisbane wreck, Mooloolaba, Sunshine Coast, Queensland, 18-06-2016

6 species sighted mainly on the top deck from the bow gun to the bow.

Gary on this excursion consisting of 1 x 64 minute and 1 x 60 minute dives in water depths from 15 m to 19 m. 15 m viz, 22 C water temp and plenty of surge.

The vis was pretty good to what it was and the surge was quite challenging when searching for and photographing very small nudibranchs on a flat substrate. The highlight was finding Diacavolinia longirostris (shell 5 mm). This is the first time in 13 years we have found this order Thecosomata.

Species List: just north of Drop Off, Currimundi Reef, Sunshine Coast, Queensland, 02-06-2016.

30 species sighted at a site just north of Drop Off, Currimundi Reef, Sunshine Coast, Queensland.

Terry, Gary and David on this excursion consisting of 1 x 84 minute and 1 x 67 minute dives in water depths from 13.5 m to 17.5 m. 10 m viz, 22 C water temp and no surge.

The swell was small and little wind was evident but the seas were up and confused from the stronger winds of the past few days. It was intended to dive at the Drop Off but we overshot that site slightly and had to content ourselves with exploring a couple of virgin patches of reef. One species new to our list was found - Dermatobranchus fasciatus, as well as several not-so-common species as revealed in the following list.
