Last dive of the trip (after missing the previous dive due to the tank shoulder strap pulling the drysuit zip open 6"). Jumped off the boat and swam towards the rock. Descended to 15m and saw the square shape of the rock loom up in front. Immediately we saw why it was called Shark Rock as a grey nurse cruised along the foot of the rock, 3 smaller fish keeping close formation beside it. We turned left and contoured at 14m, past rock face and jumbled boulders, with a sandy bottom below. At 100 bar we turned back, and within a minute saw a cuttlefish, exactly the same colour as the weed. We watched one another for a minute and then he streamlined himself and cruised off into the depths. A little further along a glimpse of brown tail revealed a large wobbegong in a cave. At 50 bar we came up to 5m and spent a couple of minutes there before swimming back to the boat. I've just done more dives in 2 days than I normally do in a year.

Dry suit dry again, and the woolly bear warm (it spent a couple of hours in the dryer).
