Species List: 19-07-2017, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld.

13 species sighted at La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld, 19-07-2017.

A single shore entry dive by Terry, Gary and David of 91 minutes. Maximum depth 7 m, 20 C water temperature and up to 5 m viz.

A gusting westerly wind blowing straight down the river toyed with us as we geared up for a late afternoon/evening dive. Conditions below, thankfully were excellent but the slugs were not around in great numbers or variety. More than half of the species types were aeolids.

Species List: 17-07-2017, Fairyland Gutters, Gneering Shoals, east of Mooloolaba, Sunshine Coast, Qld

8 species sighted at Fairyland Gutters, Gneering Shoals, east of Mooloolaba, Sunshine Coast, Qld, 17-07-2017

Gary and Magnus on this excursion consisting of 1 x 74 minute and 1 x 59 minute dives in water depths from 14 m to 17 m. 20+ m viz, 21 C water temp and a little surge.

Again great conditions! The clarity of the water was better then the previous dives. BUT the Nudibranch numbers were dramatically down. Hard searching yielded only 8 species, but I did manage to find our 711th species.

18 species sighted at Shellacey Reef, Gneering Shoals, east of Mooloolaba, Sunshine Coast, Qld, 16-07-2017

Gary and Magnus on this excursion consisting of 1 x 68 minute and 1 x 57 minute dives in water depths from 16 m to 17 m. 20 m viz, 21 C water temp and a little surge.

Again great conditions, and a great boat ride out and back in Magnus's boat, thank you. The water was very clean, you could see the bottom from the boat and visa versa. We anchored just north of the site we normally go to but the three small walls made searching fun.
