Penguin Cove is the newest attraction at this marine sanctuary (a sister attraction to Sydney Aquarium), showing off a colony of Little Penguins and explaining their importance to the shores of Manly. Talks and feeding demonstrations are offered every day, and you can get “hands-on” in the interactive rockpool, which kids love. There’s a good display of Barrier Reef fish, as well as giant sharks. If you’re braver than me, you can take the plunge with Shark Dive Xtreme, diving into the tank to swim with large grey nurse sharks, turtles, and stingrays. It costs from A$195 for qualified divers, A$270 for nonqualified divers (including an Introduction to Scuba Diving course). Bookings are essential, and you’ll save on ticket prices by booking online.
