14 species sighted at Fish Cage upriver, La Balsa Park, Mooloolah River, Sunshine Coast, Queensland, Australia 13-06-2019.

A single shore entry afternoon/night dive by Gary, Jens and David of 153 minutes. Maximum depth 5.7 m, 21 C water temperature and up to 10 m viz.

Another winter river dive has the water looking very clear. After descending we turned left to record the beautiful Phyllodesmium undulatum. Then headed north into the current which was not bad. Darkness came onto us and night began. Of note were the juvenile Atys semistriatus, the cryptic Plocamopherus ceylonicus and the Kabeiro christianae animals. For the first time in a while Cratena lineata was most common.
