Osprey Reef – North Horn

About this site

Osprey Reef is a remote offshore atoll in the Coral Sea, accessible only by liveaboard, and North Horn is its crown jewel. The sheer wall plunges from the surface to beyond 800 m, draped with sea fans and black coral trees. Regular shark feeds have habituated grey reef, silvertip, and oceanic whitetip sharks, making this one of the premier shark encounters in the Indo-Pacific.
