Species List: 02-08-2018, Northside Reef, Old Woman Island, off Mudjimba, Sunshine Coast, Qld.

33 species sighted at Northside Reef, Old Woman Island, off Mudjimba, Sunshine Coast, Qld,
02-08-2018.

David, Terry and Gary on this excursion consisting of 1 x 95 minute and 1 x 92 minute dives in water depths to 10.8 m. up to 20 m viz, 20 C water temp and no surge.

With the wind expected to swing onshore and pick-up mid-morning we selected the conservative option of diving the northside of Old Woman Island. With water clarity being so good we were not dissappointed! This was a new site for us to discover. The swell was almost nil making diving very nice. Some interesting finds were made! Four species of Thuridilla and Jorunna sp. 6 were highlights. Finding Thuridilla livida was a treat, since we don't see that species very often.
