SEA LIFE Sydney Aquarium is a public aquarium on the eastern side of Darling Harbour in Sydney, Australia, just north of the Pyrmont Bridge. Opened in 1988 as Sydney Aquarium, it showcases the marine life of Australia’s waterways alongside global species, drawing large numbers of visitors each year to its themed underwater trails.
The aquarium is best known for Dugong Island, home to Pig, a rescued dugong and one of only a handful on public display anywhere in the world. Other highlights include Shark Valley, a large oceanarium of lemon and grey nurse sharks, and the Great Barrier Reef Oceanarium, viewable via a glass-bottomed boat tour.

The Aquarium Experience
Visitors move through themed zones including Jurassic Seas, Shark Valley, Dugong Island, Discovery Rockpool, and the Great Barrier Reef Oceanarium, one of the largest reef displays of its kind. The aquarium has undergone exhibit refurbishments over the years and is an accredited member of the Zoo and Aquarium Association and the World Association of Zoos and Aquariums.
Dugong Island lets visitors view Pig from above-water platforms and underwater tunnels, alongside tankmates such as white spotted eagle rays and bamboo sharks. Pig was rescued as an orphaned calf from Queensland and could not be returned to the wild; his former companion dugong, Wuru, was also a rescue but passed away in 2018, leaving Pig as the aquarium’s sole dugong today.
Tickets & Visiting
Tickets can be booked directly through the official SEA LIFE Sydney website, which typically offers lower prices than paying at the door, along with select entry time slots to help manage capacity during busy periods. Third-party platforms such as Viator, GetYourGuide, and Tiqets also sell entry tickets and combo tours. Because admission pricing varies by season, demand, and promotion, it’s worth checking the official ticket page for current rates before visiting rather than relying on a fixed price.
For visitors combining several Darling Harbour attractions, bundled multi-attraction passes are available that pair SEA LIFE Sydney Aquarium with nearby Merlin-operated venues such as WILD LIFE Sydney Zoo and Madame Tussauds Sydney at a discount versus separate admission. Pre-booking is especially recommended during school holidays and weekends, when the aquarium can reach capacity.
