Hi All
So I chose to make the 2 hour drive up to Rainbow Beach and dive with Wolf Rock Dive yesterday.
Firstly, the team who took me out - Kev and Andrew - were fantastic. There was only 2 of us on the charter (me and some French woman), which is normally not enough for a charter, but the conditions were good so they agreed to go.
In fact, weather conditions were near perfect - sunny, minimal wind, and only slight waves. Water temperature was lovely at 25 C.
The real downside was the visibility. Apparently it has been poor since the massive Queensland floods, and with lots of rain recently, it can't have been more than 5-7 metres. I was actually surprised how close to land the rocks are (can't be more than 1km or so offshore, although the boat ride does take about 40 mins to get there), so I suppose it would be particularly vulnerable to runoff.
Despite this, the dive itself was great. A LOT of grey nurse sharks, so docile in their movements despite their fearsome looks that you almost wanted to pet them. You'd have to actively avoid hitting into them from time to time. Apparently poor visibility is good for the sharks, so I guess you can't win them all. It did mean that it was like swimming in a greenish (sharky) soup, which made for pretty poor shots - especially when the sharks were deepish at between 20 and 30m. Attached are 2 non photoshopped image (I'm writing this from my place in Noosa and I haven't got all my toys with me) taken with a Canon S95 and Canon's own enclosure - you can see I was struggling with white balance, and I suspect having a strobe would have enhanced the particulate matter in the water. There was also a pleasing array of colourful reef fish around, although no manta rays
In summary, an amazing dive which I would absolutely love to do again with better visibility. I suspect winter would be a winner, and at 19 deg or so water temp in winter, still pretty warm by the NZ standards I am used to!
Hope that helps
