Sydney Aquarium is a public aquarium located in the city of Sydney, New South Wales, Australia. It is located on the eastern (city) side of Darling Harbour to the north of the Pyrmont Bridge. It is a full institutional member of the Zoo and Aquarium Association (ZAA) and the World Association of Zoos and Aquariums (WAZA).
The aquarium contains a large variety of Australian aquatic life, displaying more than 650 species comprising more than 6,000 individual fish and other sea and water creatures from most of Australia's water habitats. Its key exhibits in the aquarium are a series of underwater, see-through, acrylic glass tunnels where sharks swim above visitors, and recreation of a Great Barrier Reef coral environment. The aquarium was designed by Australian architects to resemble a large wave, to complement the underwater theme of an aquarium and the maritime theme of Darling Harbour, and took nearly two years to build. The Great Barrier Reef complex which opened in October 1998 continues this same theme.
