Scuba Diving in Blue Maomao Arch, Poor Knights Islands

A natural archway with thousands of blue maomao fish and the signature dive site that caused Jacques Cousteau to rate the Poor Knights as one of the top ten dive sites in the world. The arch is in 7-8 metres/23-26 feet of water and accessible to divers of all levels. Massive schools of blue maomao are accompanied by kingfish, snapper, morays and nudibranchs.

Once you're inside it's a colourful new world that awaits you. The light goes through both ends and a big opening on the side, flooding the arch with god-sent light beams. Some days the place is black with fish! So much so that you could not see the other end of the arch even in clear water: demoiselles and blue MaoMaos are engaged in a territorial fight and huge schools push each other on the walls, creating a smooth ballet.
