 24 species sighted at Nudibranch Day Sunreef Trench OWI NW Reef, Sunshine Coast, Queensland, Australia. 26-08-2023.

A double boat entry dive with Gary and friends of 50 minutes each. Maximum depth 19.5 m, 21 C water temperature, up to 15 m viz.

A bit of wind was predicted and under a metre of swell. Nudibranch Day was going to happen. Off we went to Trench. The anchor missed the mark by miles so we searched a flat featureless substrate. The wind picked up and we moved to the NW Reef OWI. This site was fantastic! Seeing Okenia hallucigenia on the pink bryozoan was a treat. And there was finding the large Marionia sp. 5, another level! WOW! Plus 3 New Species. Need to dive OWI NW Reef more!
