Once all divers were up we headed clockwise round Broughton Island to a sheltered spot for a bite to eat (rolls & cheese, chicken noodle soup, biscuits and lollies).

Then we were first group in for the second dive. This was through a series of spectacular underwater canyons, with fairly appreciable wave action (which would appear to be the normal state of affairs, judging by the floor of the canyons which consisted of sizeable rocks worn smooth). Technique was to let the surge wash you forwards, then hang of with fingertips or elbows to resist the backwash.

At the farthest point, we rounded a corner to find ten or more grey nurse sharks silhouetted against the green water beyond. Dani said afterwards it was the most she'd seen at that point, so we felt very fortunate.

All too soon it was time to turn around and return the way we came, surfacing via the anchor line (good navigation by our dive leader). The trip back went much more quickly than the outward journey with much to reflect on and talk about.

I'd recommend Let's Go Adventures to anyone, and would certainly return to Nelson Bay myself.
