11 species sighted at La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Queensland, 19-03-2017.

Julie, Simon and Terry on this single shore entry dive, of 96 minutes. Maximum depth 5.5 m, 27 C water temperature and up to 2 m viz.

Simon was visiting from Lismore and was keen to see what treasures the river held. Visibility was down due to recent rains. Simon managed to find a Pleurobranchus weberi, which we have not seen for some time. It is good to know that they are still around. Going back through our records, we realise that the water temperatures have been, on average, 2 degrees higher this summer. Our hypothesis is that it is a combination of the higher temperatures and the relatively low rainfall that has resulted in the lower number of species that we are seeing.

Gary and Elisha on this single shore entry dive, of 180 minutes. Maximum depth 6.2 m, 27 C water temperature and up to 5 m viz.

The large and numerous Flabellina rubrolineata of up to 60 mm, were again impressive and quite beautiful to observe. The current was almost non-exsitent and the viz was nice. I was quite happy to see Plakobranchus sp. Congratulations to Elisha for her first 180 minute dive!

Gary solo on this single shore entry dive, of 181 minutes. Maximum depth 6.5 m, 27 C water temperature and up to 6 m viz.

Dispite the rain and weather there was very little current on this dive and the water pretty clean. It was quite nice running into the large and numerous Flabellina rubrolineata. These animals were up to 60 mm
