During the summer months, big schools of large Yellow Tail Kingfish can be seen.
Popes Eye 11m Open Water (1)



Pope's Eye (OW, MR) Depth 12m (40ft) A man made basalt rock annulus. It is the foundation of what was to be an Island Fort built in the 1880's.

The inside of Pope's Eye provides a safe anchorage in 2-3 metres of water while outside, the rock wall extends to a depth of 12 metres. While the best time to dive Pope's Eye is on the start of the ebb tide, it provides almost all weather, all current diving. Pope's Eye is a must for all divers.

The wall comprises small overhangs which are home to a vast array of invertebrate life and fish, in particular the beautiful Blue Devil fish. On the top of the hole there are several rock bommie's which host hundreds of fish of many species.

Quarantine Drift 21m Open Water (2)

A scallop drift is a much slower pace 1 - 2 knots.
