A single solo shore entry dive with Gary of 286 minutes. Maximum depth 6.1 m, 27 C water temperature, up to 6 m viz.

Well it's mid-week diving again and a vacant park in which to happy. A 1.8 m tidal flow along with early morning southeast winds before possible rains, what could be better?

Interesting critters were recorded today. Costasiella sp. 2, Dermatobranchus sp. 15, Elysia pusilla, Idaliadoris maugeansis and Myja sp. 1 kept me smiling.

Species List: 29-01-2023, Nudibranch Day Sunreef, Trench area, Gneering Shoals, Mooloolaba, Sunshine Coast, Queensland, Australia.

16 species sighted at Nudibranch Day Sunreef, Trench area, Gneering Shoals, Mooloolaba, Sunshine Coast, Queensland, Australia. 29-01-2023.

A double boat entry dive with Gary and David plus others of a 50 minute and 37 minute dive. Maximum depth 19.5 m, 24 C water temperature on bottom, warmer above that, up to 10-15 m viz.

To the Trench we were supposed to go but ended up in 20 m of water no surface current about 100 m to the south. After the first dive we headed to Shellacey Reef for a shallower dive only to find a ripping 3 knot surface current. Tried to get to the bow but no go. In that time the anchor line got caught in the prop. We then headed back to where the first dive was. Not a lot of species but some nice finds were had. One of the divers recorded a small blue with orange margin nudibranch. This looks like a new species of Nembrotha (an educated guess).
