32 species sighted at Fish Cage upriver plus, La Balsa Park, Mooloolah River, Mooloolaba, Qld. 29-07-2020.

A single shore entry dive split in two by Gary, Tracey and Harvey of 200 minutes. Maximum depth 5.9 m, 20 C water temperature up to 8 m viz.

Magic day when we arrived sunny, smooth water, light winds... the viz was great until about 75 minutes into the dive, after hearing a strange kind of boat motor noise we were engulfed by a dark thick mass off shit that steak-rolled us. We all made out way to the surface and were gob-smacked. We finned on the surface to the stairs and looked down only to see the water was clear again...so off we went. Some very nice finds from under rocks today!

Another Melbourne kind of winter day is here! The water is still quite clear even tho we have had all night rain. We recorded a new species of Polycera, exciting! A Goniodoridella animal with brown collar and brown sides to the body was also recorded, we will separate this one as a new species...unusual. Niparaya sp. 12 was also a great find and we have not seen it since the big flush-out. Another great outing for sure.
