Sydney Aquarium

Confront dangerous crocodiles, explore Australia's largest river system, and wander through a tropical mangrove swamp at the Sydney Aquarium. In the Seal Sanctuary, visit with seals and "walk on water" in a specially constructed viewing area with glass flooring and walls. And don't miss the Open Ocean Floating Oceanarium, where you can walk beneath the ocean as you are surrounded by the world's largest collection of sharks in captivity — some over 11 feet long. And don't forget to stop by the largest Great Barrier Reef exhibit in the world, home to a myriad of tropical fish and live corals. This is a truly spectacular attraction for all ages.
