Cairns Aquarium, which opened in 2017, provides a fascinating look at some of the Great Barrier Reef’s marine habitats and wildlife. The aquarium’s purpose is to promote protection of this World Heritage-listed habitat in the Wet Tropics of Far North Queensland. At the aquarium, more than 15,000 animals reside in ten ecosystems and 70 habitats, including mangroves, tropical rainforests, river systems, the Coral Sea, and the Great Barrier Reef. See dangerous marine stingers and learn about the reef’s perils, see barramundi and crocodiles in a billabong river system, and meet scalloped hammerhead sharks up close. Lunch and snacks are available at the on-site Italian restaurant.
