David on this excursion (buddied with Marina Goymer) consisting of 2 x 55 minute dives with Sunreef Scuba Diving Services of Mooloolaba from their vessel 4 Shore. Depths from 12 m to 21m, 25C water temp, 10m viz and no surge.
With my regular dive buddies enjoying the delights of Nelson Bay, NSW I decided this would be a good chance to check out the sea slugs on HMAS Brisbane. It has been some time since my last dive there. Although the species count was low it was not from lack of effort. Marina proved an excellent buddy being like-minded in preferring to take the time to find and photograph the smaller critters.
No surface or substrate shots - oops!
