| Divemaster: Matt McPherson, Plunge Diving, Mosman NSW Plunge Diving is located on Sydney Harbour with its own warf and beach access. The buildings housing Plunge Diving were the old mine laboratory built at Chowder Bay in 1892 for the Submarine Mining Corps. Now the whole facility is a part of the Sydney Harbour Federation Trust. Some of the defence force building have been converted into accommodation, and there is a cafe next to Plunge Diving near the Clifton Gardens beach. Peter and Zoe who run Plunge Diving were simply great to both of us and they run a great setup. We were assigned Matt McPherson as our Divemaster to show us around the site, with three others joining us in the group. Plunge Diving have their cylinders and regs setup as DIN by default, so it was nice to be able to go back to my usual setup without my DIN to Yoke adaptor. Entry was by giant stride from the warf, taking care not to step out too far onto the tracks of the slipway. The dive considted of following a large chain out to a ship mooring buoy. There wre four chains going in different directions from this buoy to explore for marine life. With a silty bottom and shallow depths, good buoyancy control is required to avoid silting up the area. Our group was the first. So we were trying to stay ahead of the Open Water student groups who were quite likely to stir things up a bit. It was a peaceful, relaxing dive, slowly proceeding along checking out the macro marine life. Sea horses, stingrays, octopus were all seen, plus Matt also located one of the Angler Fish which are at home in the area. A very pleasant dive. I was starting to be too buoyant in the shallows towards the end of the dive because I was slightly under weighted for the 12 litre cylinder. It felt strange finishing a dive with so much air in reserve. Exit was via the Clifton Gardens beach. The books "Doing It Right" and "Dress for Success" were on display in the dive shop and I purchased copies. We also purchased a few of the nice diving T-shirts that were available. Plunge Diving were happy to mail this stuff to me so that the chance of being overweight on the flight home was avoided. I left my gear at Plung Diving so that it would be easier to come back the next day. |
