Species List: 29-06-2018, Trench, Inner Gneering Shoals, off Mooloolaba, Sunshine Coast, Qld.

23 species sighted at Trench, Inner Gneering Shoals, off Mooloolaba, Sunshine Coast, Qld, 29-06-2018.

Gary and David on this excursion consisting of 1 x 77 minute and 1 x 72 minute dives in water depths from 15 m to 19 m. 12 m viz, 20 C water temp and moderate surge.

Upon descent we had intended diving the northern side as we did last time and then reeling over to the southern wall but arriving at the bottom we found the anchor had dropped onto the southern side and the chain laid up the sand gutter. So we reversed the dive plan and explored the southern side first. It seemed as though there were not as many slugs over there but a review of the images proved that be an erroneous impression. Finds of note include: Aglaja sp. 3, Caloria indica, Dermatobranchus tuberculatus and Verconia sp. 2.
