Grey Nurse Sharks (also known as Sand Tiger Sharks or Ragged Tooth Sharks) are endangered and one of the shark species endemic to Australia. They are mostly harmless and shy of humans - although as with any wild animal there is always the risk of aggression if provoked. They are super special to me and make me VERY happy to see them, and I know that many other divers feel the same way!
If you want to see them then you would normally have to drive a good few hours out of Sydney to some of the special dive sites in New South Wales, such as Byron Bay (Julian Rocks), South West Rocks, Forster or Nelson Bay. But sometimes we are lucky enough to see them in Sydney too. I saw a beautiful one this week whilst on a shore dive. Fingers crossed it stays around and becomes a more regular sighting!
