Species List: 22-06-2018, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld.

10 species sighted at, La Balsa Park, Mooloolah River, Mooloolaba, Sunshine Coast, Qld, 22-06-2018.

A single shore entry dive by Gary and David of 55 minutes. Maximum depth 5.7 m, 20 C water temperature (rounded up) and maximum 8 m viz.

A shorter than usual immersion courtesy of a couple of equipment failures. We probably only covered about 10 lineal metres of river bed but managed nevertheless to sight more species than we sometimes record in dives of three times the duration and ten times the distance covered. The substrate has been significantly altered due to the recent river bed profiling operations.

Species List: 16-06-2018, Terry’s Delight, Arkwright Shoals, off Point Arkwright, Yaroomba, Sunshine Coast, Qld.

29 species sighted at Terry’s Delight, Arkwright Shoals, off Point Arkwright, Yaroomba, Sunshine Coast, Qld, 16-06-2018

Gary and David on this excursion consisting of 1 x 84 minute and 1 x 76 minute dives in water depths from 13 m to 17 m. 20 m viz, 22 C water temp and no surge.

The ideal surface and diving conditions persisted so we ventured out on back to back excursions, this time a little further afield up to the Arkwright Shoals. A similar species count eventuated but some different species recorded this time. Ardeadoris carlsoni, Chromodoris magnifica and Dermatobranchus sp. 10 were uncommon finds. The deep crevasses at this site provide an enjoyable substrate to search for our elusive quarry.

Species List: 15-06-2018, North West Reef, Old Woman Island, off Mudjimba, Sunshine Coast, Qld.

27 species sighted at North West Reef, Old Woman Island, off Mudjimba, Sunshine Coast, Qld,
15-06-2018.

Gary and David on this excursion consisting of 1 x 98 minute and 1 x 93 minute dives in water depths from 8 m to 12 m. 15 m viz, 22 C water temp and the slightest of surge.

With the offshore winds expected to pick-up mid-morning we selected the conservative option of diving inshore at Old Woman Island. We banked on the current water clarity extending to the island and we weren’t disappointed. Surface conditions were ideal. Ardeadoris angustolutea and Verconia norba were uncommon finds together with the Aplysia parvula, the latter found dining on the red algae.
