Species List: 08-09-2017, Northside, Old Woman Island, off Mudjimba, Sunshine Coast, Qld.

26 species sighted at Northside, Old Woman Island, off Mudjimba, Sunshine Coast, Qld, 08-09-2017.

Julie, Terry, Gary and David on this excursion consisting of 1 x 90 minute and 1 x 91 minute dives in water depths from 11 m to 14.5 m. 12 m viz, 21 C water temp and some occasional very slight surge.

The south west wind was predicted to get up to 15 knots early in the day (20 knots offshore) but then drop away in the middle of the day so we elected to to anchor on the north side of Old Woman Island in the lee. By 08:30 it was blowing 20 knots there out of the SSW. We dropped anchor at a random blip on the sounder and were pleasantly surprised at the pretty little site. We were rewarded on the second dive with our 714th species - an undescribed Marionia. We were joined by a number of vessels sheltering from the unexpected wind strength but as predicted it did drop away to less than 10 knots.
