Having arrived back at Portsea Pier with plenty of air left in our cylinders, Neil and I decided to burn it off with a relaxing pier dive taking in the nearby reef.

I found that I was a bit under weighted and had problems staying under for much of the dive. I was using my Faber 15 litre steel cylinder, so I made a mental note that I would need even more weight with my 12 litre one.

Neil found a rather large weedy sea dragon under the pier. I spotted another one as we headed over to the reef.

By the time we reached the reef I was really struggling to stay down. Getting low on air we headed back to the pier.

This is just such a delightful dive site to explore. I must get back and dive it more often.

Dive over, we headed back to our cars only to find Ed had already arrived for the afternoon dive. Neil headed off home, and I switched cylinders ready for the afternoon dive. I had lunch and headed out onto the pier where I found Hev, Matt, Peter and Ed all waiting for the dive boat.
