Species List: 31-12-2021, Fish Cage to Rotunda, La Balsa Park, Buddina, Sunshine Coast, Queensland, Australia.

 17 species sighted at Fish Cage to Rotunda, La Balsa Park, Buddina, Sunshine Coast, Queensland, Australia. 31-12-2021.

A single shore entry dive with Gary and David of one 278 minute dive. Maximum depth 5.9 m, 25 C water temperature, up to 4 m viz.

With quite a bit of rain and a brown river we thought we would give it a go, the last dive of 2021. 2021 was the most productive year ever. There was quite a bit of fluff in the water giving us a 1.5 m viz to challenge us. The silt was very heavy sometimes over 40 mm thick. This looks like to be the reason that the nudibranch species list is so low. The best part of this dive was recording 5 Cratena pawarshindeorum.
