It's a great dive for beginners as it's almost impossible to become disoriented, and allows the diver to get out at almost any location along the rock wall. In addition it is sheltered from west-southerly swells by the main breakwater to the south and is also well protected by wind from most directions, however easterlies are not favourable to this location.

There are many species of marine life here, including weep, conger eels, sea dragons, abalone, crayfish, wobbegongs, sharks, stingrays and the occasional seal.

It has been reported that penguins have been seen off the breakwater at night

Vehicles can be parked along the breakwater, making gearing up and entry to the water easy. Toilets, showers and changerooms are available at the shore end of the breakwater.

Line fishing from the breakwater is common, so be careful of fishing line. (It's a great place to pick up snagged lures, sinkers, etc).

The Emily is a intact wreck laying upright on her keel in 24m of water between 2 rocky reefs. This is a great dive for both open water, and is available for penetration for wreck / cave certified divers.

The northern side rises from 24m with terraces providing shelter for crays and abalonies. Seals are also frequently in this area.

The south - west side is shaped like an amphitheatre with a depth reaching 30m and a base area equivalent to the size of 3 tennis courts. Marine life is abundant, including a good variety of pelagic species. A small surge can be present, but there are no tidal flows or currents. A Gannet colony occupies the land area of the rock. While in the area, consider doing a dive on the Emily. Watch for cray-pot lines when in this area.

The boulders to the East are full of sea caves, and caverns home to a wealth of marine life. There are 4 large caves at around 14m of depth, one that has a slot in the roof leading to a small

chaber above known as "The Cockpit". (Which can hold a maximum of 4 divers at a time).

This area is home to over 30 individual dive sites with depths ranging from 6 – 36 metres, which include kelp forests, swimthroughs and sandy areas.

It is recommended not to dive in this area / with the seals between October through to January, as this is breeding season for the Seals (and therefore eating season for great whites).

Boats can be launced from the Life Saving Club.
