The weekend is here and with a 1.8 m tidal flow we entered the water at 3 hours before high tide. Yes the current was very healthy! I went low while David went high, he found some interesting species from under rocks. Not a bad dive!

23 species sighted at Fish Cage, La Balsa Park, Mooloolah River, Mooloolaba, Qld. 17-09-2020.

A single shore entry dive Gary and Sheryl of 200 minutes. Maximum depth 6.0 m, 21 C water temperature, 8+ m viz.

Before Sheryl goes back to sailing we thought a mother dive was in order. The river had cleaned up quite nicely with over 8 m viz. A little current but doable. Not a lot of species but some interesting ones non the less. Another Niparaya different from the rest! Plus a green one below it another new one!
