Advokat, great to see that you appreciated the Valiant, although it is starting to corrode badly, especially around the bridge and superstructure.
If you are diving out of Terrigal, now's the time to visit Foggy's Shark Cave. I dived it on Sunday - flat calm and warm water, viz to 20m down to 25m then about 8m on the sand. There were two juvenile Grey Nurse sharks in residence, and about seven other adults but they were not in sight. Foggy's is 29 metres to the top of the reef and down another 7m to the cave - highly recommended.
