Manta Wall

Manta Wall lies in the far northern section of the Great Barrier Reef, off the coast of Queensland, in a remote area well beyond the more heavily visited sites near Cairns and Port Douglas. This stretch of reef is typically reached only by liveaboard, given the distance from the mainland, and forms part of the broader ribbon reef system that runs along the continental shelf edge in this part of the Coral Sea. The wall tops out at a shallow maximum depth of around 9 metres, and divers have reported manta rays passing along it, though sightings are not a given on every dive.
