29 species sighted at The Trench on Nudibranch Day at Sunreef, Gneering Shoals, Sunshine Coast, Queensland, Australia. 13-09-2025.
A double boat entry dive with Gary, Kelly-Anne, Tomas and friends of x2 50 minutes, maximum depth 18 m, 20 C water temperature, 15 m viz.
Rain starts the day with overcast skies and over a one metre swell, that means a little surge, but very doable. Some very nice nudibranchs were seen by all.
