This ain’t the place to come if you’re on your way to Manly Beach for a surf. Underwater glass tubes enable you to become alarmingly intimate with 3m grey nurse sharks. Reckon they’re not hungry? Shark Dive Xtreme (introductory/certified dives $280/205) enables you to enter their world.
Upstairs, the residents of the penguin enclosure have lawless amounts of fun. Manly has one of the last mainland colonies of little penguins in Australia, and this display aims to educate people about these cute-as-a-button critters (don't fret, none of these little guys were taken from the wild).
