Osprey Reef / Australia

Sharks

Osprey Reef is located in the Coral Sea near Ribbons Reef and it looks like a huge underwater dome with a lagoon inside. The lagoon has an incredibly large size: 25km/15mi length and 8km/4mi width and its first level descends to 40m/131ft. The vertical walls that reach the bottom of the ocean partially resemble a large ladder. The length of the wall increases together with the descending. After the 40th step, there’s a 100m/328ft stair-well, than 250m/820ft and finally 8km/4mi stair-well that runs into the ocean depth. Because of the reef’s remote distance from the shore, daily dives are impossible. The routes for safari diving are available all year round. Feeding of the sharks – a popular attraction of the Osprey Reef should be better performed at the northern part of the reef – the North Horn.
