With over 15,000 creatures on display, the aquarium showcases the interconnected ecosystems of Tropical North Queensland, crucial for the survival of the Great Barrier Reef. Themed exhibits include the Open Ocean, The Great Barrier Reef, River Monsters, Rivers & Streams, Life in the Mangroves, Coral Atoll, Reptiles and Amphibians of the Rainforest, and Dangers of the Reef, among others. Each exhibit is a vivid reminder of the incredible biodiversity this region supports.

You can even peek behind the scenes at the Research Facility. Fun fact: the Great Barrier Reef is so large, it can be seen from space, and it's home to over 1,500 species of fish. This makes Cairns Aquarium an ideal spot for both curious travelers and budding marine biologists.
