About CORALIE BAY - GMI
Coralie Bay is an easy Great Mercury Islands bay dive with plenty of room to explore across kelp-covered reef and scattered sand patches. Divers use it as a relaxed local site where the middle of the bay drops into deeper water while the broader reef stays approachable and scenic. It suits divers who want an uncomplicated temperate-reef outing built around fish life, rays, and general reef wandering rather than aggressive current or depth.
