Went to Sydney Aquarium at Darling Harbour recently. Haven't been for years. It's pretty cool! You can see sharks swimming above and around you as you walk through parts of the tank. It's all 'covered' with glass. No need for diving underwater in a metal cage to see all this or anything. Lots of other cool sea-life to see as well from seahorses to platypus etc... Definitely worth a visit. $27.50 for adults.
