Hey
Do you have an advanced open water PADI SCUBA diving qualification? Or an equivilent that allows you to dive to 30 metres?
If so you can do a dive with grey nurse sharks. Grey Nurses are gentle, passive and even inquisitive creatures and not aggressive at all - but they LOOK really mean. There is a permanent Grey Nurse colony on the North NSW coast called Fish Rock Cave. The dive centre who run it is in the town of South West Rocks. The dive also goes through a 120m long cave too, which is amazing (BYO water proof torch!). Not everyone likes cave diving but you can no doubt just go and hang with the sharks only.
I did a solo dive after the first main dive and came 2 metres away from a 3 metre long Grey Nurse. I was totally on my own, nobody knew where I was, at about 25m depth, with this massive shark right infront of me totally motionless watching me. We both sat for at least a minute. It slowly swam away but kept coming back every minute or so and generally hung around. I was terrified!! We really connected, like we had total eye contact, and I knew that i was in HIS domain. I spent about 10 minutes with him lurking doing exercises and checking out the coral, and then surfaced without incident.
Its a BRILLIANT dive though. Clear relatively warm water, hundreds and hundreds of sharks, the cave, and good diverse fish and colourful reef. Its the best dive i've done on the Australian mainland. But it does get down to 30m so you need the right ticket.
MSG me if you want more info.
