Species List: 14-07-2019, HMAS Brisbane wreck, Mooloolaba, Sunshine Coast, Qld.

11 species sighted at the HMAS Brisbane wreck, Mooloolaba, Sunshine Coast, Qld, 14-07-2019.

A double boat dive by Gary, Kelly, David and Amanda of 48 and 49 minutes. Maximum depth 19.9 m, 20 C water temperature and up to 15 m viz.

Nudibranch Day again with Sunreef. This time the wreck not the reef. After the big swells of late the wreck seemed to be scarse in the nudibranch population and food sources. Never the less we did manage to find some interesting species. Kelly found Diacavolinia longirostris in a Black Sun Coral, Tubastrea, probably being fed on.

Species List: 10-07-2019, Fish Cage upriver, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld.

18 species sighted at Fish Cage upriver, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld, 10-07-2019.

A single shore entry dive by Gary and Sheryl of 131 minutes. Maximum depth 5.4 m, 21 C water temperature and up to 5 m viz.

Another beautiful winters day in paradise. The water temp was 21C this dive...where did that come from? This time Sheryl and I drifted upriver to the trees and descended. The vis in the river is clearing up and there were times when it was 5 m. There were a few species that were nice to find. Sitting on top of a small rock was a hydroid with 5 Tenellia sp. animals, this was Sheryls dream come true. Another good species to see again was Aglaja fulvipunctata, although these animals were quite small, about 4-5 mm. I find it amazing that the Pteraeolidia semperi numbers at the Toilet Block are high and here at Fish Cage quite low.
