Species List: 28-12-2018, Fish Cage, Mooloolah River, La Balsa Park, Mooloolaba, Sunshine Coast, Qld.

21 species sighted at upriver Fish Cage, Mooloolah River, La Balsa Park, Mooloolaba, Sunshine Coast, Qld, 28-12-2018.

A single solo shore dive by Gary on this excursion consisting of 1 x 161 minute dive in water depth up to 5.7 m, 3 m viz, 26 C water temp.

Another inviting day and another interesting dive in the river. Descending after drifing upriver to look at sand, I was surprised to find, as soon as I touched bottom, Costasiella sp. 2 and more after that. Not a single Unidentia species was found! Another Colpodaspis sp. 1 was found but the current swept it away while readying the camera. The water temp was a very comfortable 26C.

16 species sighted at Mooloolah River, La Balsa Park, Mooloolaba, Sunshine Coast, Qld, 27-12-2018.

A single shore dive by Terry and Julie on this excursion consisting of 1 x 137 minute dive in water depth up to 6m, 2m viz, 25 C water temp.

Despite the holidays the park and carpark were still reasonably quiet today, although there was a lot of boat traffic. Visibility varied during the dive due to a stingray feeding in the sand up-current from us, causing total silt-outs.

A single solo shore dive by Gary on this excursion consisting of 1 x 181 minute dive in water depth up to 6.2 m, 2-3 m viz, 26 C water temp.

The day was looking like a cracker so off to the river I went anticipating huge crowds, but there wasn't. There was a bit of current in the beginning but all in all it was a good dive. Finding Diversidoris aurantionodulosa from under a rock was a great find. Quite a few bubble shells were found as well. I actually thought I had found a Corambe species also from under a rock, but after sending it to Bob Burn, he indentified it as a Polyclad.
