After 9 months and more than 100 posts it’s finally happened…I have a couple of dives to post about, so you know it’s not gonna be a brief post!! Given that my financial and time priorities lie elsewhere for the time being, it’ll probably be as long again before the next dive even though I’m psyched up for some more!
Jodie’s brother, Ben (aka Slothy Boy) and I were booked in with South West Rocks Dive Centre for 7am Saturday morning. After the usual formalities (fairly straightforward as I have all my own gear beside tanks) the boat was loaded up and we were off for the 25 minute trip to
Fish Rock. Surface conditions were good, with very little swell and clear skies. There was a bit of a breeze making the surface of the water a bit choppy, but we moored on the sheltered side of the rock.
Dive 1 was to be all the way through Fish Rock Cave, which is a cave that runs over 100 metres through the middle of Fish Rock. The cave profile is
here.
After a briefing from the dive master I promptly geared up, did a giant stride off the back of the boat and floated around waiting for most of the 6 others to get their act together. The water was quite cool at first, although my dive computer registered 19 degrees C which isn’t too bad really and with a 2 piece dive suit you warm up soon enough.
Once everyone was ready we descended to 23 metres where the “deep entrance” of the cave lies and after a quick torch check we started filing into the cave. It’s quite narrow to start off with, before widening once you rise up one of the chimneys to the upper section of the cave.
Being in a group doesn’t give much opportunity to do your own exploration of the cave, but I did take the opportunity to shine the torch around and it’s pretty impressive looking around and seeing the fissures extending above you. For me, the most amazing part was approaching the shallow entrance when the light starts penetrating through, throwing up the spectacular silhouette of fish teeming through the shallow entrance to the cave, which is around 12 metres deep.
The shallow entrance to the cave holds an incredible amount of life. I still had about 150 bar of air by the time we made it there, and we hung around for a while. There were up to a dozen grey nurse sharks of varying sizes slowly cruising along the gutter and into the cave. A couple of huge bull rays and wobbegong sharks were relaxing on the bottom, as well as a couple of moray eels poking their heads out of their lairs.
After a while we made our way back around the outside of the rock to the mooring line and ascended to the surface with a standard safety stop at 5 metres for 3 minutes.
We relaxed on the boat for a surface interval of about an hour before it was time to get the second dive underway.
Dive 2 was to be a more relaxed dive back around the outside of the rock to the cave’s shallow entrance. Whilst it was a great experience to go through the cave on the first dive, I really enjoyed the second one because there was more opportunity to do our own thing and I found the most enjoyable section to be in and around the shallow cave entrance. When the rest of the group went elsewhere Slothy Boy and myself ventured back into the cave to take some more photos, do some exploration and hang around the side of the gutter while the sharks cruised past. The critically endangered Grey Nurse Sharks are beautiful, amazing creatures to watch as well as being extremely placid and virtually harmless to humans. Even so, it’s certainly awe inspiring when you’re sitting there and a shark larger than yourself is eyeing you off as it’s heading towards you before gliding past just half a metre away!
Aside from the sharks there’s quite an amazing diversity of marine life in the area. We saw angel fish, a couple of rare leafy scorpion fish, quite a few moray eels, plenty of friendly blue gropers, some clown fish, heaps of snapper, lobster, bull rays, lionfish, bullseyes, starfish, wobbegong sharks plus just far too many other miscellaneous fish to name including many large schools all around.
I hadn’t dived Fish Rock before but had heard so much about it, so I’m glad to have finally taken the opportunity to dive there. It definitely lived up to the hype as far as I’m concerned and is right up there with the best dives I’ve ever done. I’m looking forward to getting back out there again in the future. Thanks to Slothy Boy for organising it and bringing along the camera with underwater housing. Between the 2 of us we took heaps of photos, of which most were pretty dodgy but there were still a few good shots. There are a couple below and I’ll follow up with some more once I sort them out a bit.
The stats from my dive computer were:
Dive 1
Max Depth: 23 metres
Average Temp: 19 Deg C
Bottom time: 44 min
Surface Interval: 1hr 5 min
Dive 2
Max Depth: 19 metres
Average Temp: 19 Deg C
Bottom time: 55min
We had about 10-15 metres visibility and there was just a minimal amount of both surge and current. I travelled through quite a few thermoclines (rapid change of temperature) and it’s always nice going from cold to warm but terrible the other way. You can see them coming up because the water shimmers in the same way that you see the heat rising up off a hot road. The most severe one was actually in the cave, and the warm change actually made my eyes water!
Nitrogen absorption remained in the “green zone” throughout both dives according to the computer, so they were both fairly conservative profiles.
