Mary Island Wall

Mborokua (Mary) Island is a remote, jungle-clad, uninhabited, extinct volcano lying west of the Russell Islands. It is surrounded by deep walls with prolific marine life including barracuda, manta rays and sharks. It was 300 metres deep with nowhere to anchor so the Princess II drifted close by as we dived along this stunning vertical wall. 

The water was so clear that you felt like you were flying. However, my long-range vision was obscured by the gorgonians and huge schools of fish including barracudas and jacks. Manta rays are often seen here but I only saw four white-tipped reef sharks that disappeared very quickly!
