Sydney Aquarium lies just north of the eastern end of Pyrmont Bridge in a building jutting out into the harbour. It shares the site with Sydney Wildlife World.
It is a place for close encounters with the denizens of the deep where various Australian water environments feature the sea creatures in each of them.
From sharks to clownfish and jellyfish, you'll find them in their own particular habitats.
