Species List: La Balsa Park, Mooloolah River, Sunshine Coast, 25-05-2014

10 species sighted on a single night shore-entry dive at La Balsa Park, Mooloolah River, Sunshine Coast.
Julie, Terry and David on this dive of 131 minutes duration in water depths to 6.6m. 4m viz and 22C water temp.

The exceptional run of summer weather just one week out from the official start of winter ensured that the crowds were out enjoying the river bank and small craft were returning to harbour well into the evening. We received many strange looks as we waddled into the river just before dusk. Whilst the number of different species found was unremarkable the fact that no less than three new ones to our list were among them is exciting.
