The Great Barrier Reef’s underwater observatories offer a calm, fascinating way to view the reef’s colourful marine life.  See the reef without ever getting your feet wet. Located on select reef pontoons, these enclosed observation decks sit beneath the surface, allowing you to watch fish, coral, and other creatures in their natural habitat through large viewing windows.

Perfect for non-swimmers, young children, seniors, and anyone who prefers to stay dry, underwater observatories make it easy to enjoy the reef from a whole new perspective. As fish swim past and coral gardens sway in the current, you’ll feel immersed in the reef’s vibrant world—all from the comfort of a seated, air-conditioned space.

From Cairns, underwater observatories are available with tour operators like Sunlover Reef Cruises and Great Adventures at reef locations such as Moore Reef and Norman Reef. Some observatories also offer fish feeding sessions, where you can watch schools of reef fish up close as they dart past the windows.
