Reef HQ, the worlde's largest living coral reef aquarium, is not only a uniquely North Queensland attraction, it is the education centre for the Great Barrier Reef and a 'must see' for both locals and visitors to the region.  

Each exhibit is like looking through a window to the many wonders of the Great Barrier Reef. The main attraction, the Underwater Discovery Tunnel, bisects a 750,000 litre Predator Exhibit and a 2.5 million litre Coral Reef Exhibit where visitors have a fish-eye-view of the coral ecosystem.
