Depth: 5 m (16 ft) to 65 m (213 ft)

Level: Advanced Open Water and beyond.

Skull Rock (or Cleft Island) is a very rewarding boat dive site for adventurous divers on the eastern side of Cleft Island. The sheer granite rock formation and caves that rise some 113 metres above sea level look skull like from a distance.

Cleft Island is part of the Anser Group of islands at Wilsons Promontory, Victoria, Australia. It's located within the Wilsons Promontory Marine National Park in the often wild seas of Bass Strait.

Diving Skull Rock

The rock formation continues 65 plus metres underwater and makes for awesome diving. There are underwater caves and playful Australian Fur Seals often come to see divers here.

Because of the depths that can be reached here, plus the sometimes strong currents, Skull Rock is best dived at slack water. It drops off steeply, and is well worth a dive on the rare days conditions allow.

Ideal Conditions: Skull Rock is best dived with calm seas, no swell and no wind. Light offshore north-easterly to south-easterly winds may be acceptable. Because of the depths that can be reached here, plus the sometimes strong currents, Skull Rock is best dived at slack water. See WillyWeather (Cleft Island) as a guide for the tide times and the height of the tide.

Bass Strait Warning: Always keep an eye on sea conditions throughout any shore or boat dive in Bass Strait on Victoria's coastline. Please read the warnings on the web page diving-in-bass-strait before diving or snorkelling this site.

Wilsons Promontory Marine National Park

This site lies in Wilsons Promontory Marine National Park, Victoria's largest marine sanctuary. There is a huge diversity of marine life within the waters at the Prom. Brilliantly coloured fish are present such as the Red Velvetfish, Eastern Blue Groper and Wrasse as well as Leafy Seadragons and schools of Barber Perch. Intertidal molluscs such as limpets and snails, as well as anemones, brittlestars and seastars, are also common within the waters.

Divers will experience fascinating sponge gardens which consist of a techni-coloured assemblage of sponges, sea tulips, sea whips, lace corals and seafans. Octopus emerge at night whilst sharks and rays roam the sandy areas.

The offshore islands support many colonies of fur seals and oceanic birds such as Little Penguins, Fairy Prions, Silver Gulls and Pacific Gulls.

You are not permitted to carry a spear gun while snorkelling or scuba diving in Wilsons Promontory Marine National Park.

DISCLAIMER: No claim is made by The Scuba Doctor as to the accuracy of the dive site coordinates listed here. Should anyone decide to use these GPS marks to locate and dive on a site, they do so entirely at their own risk. Always verify against other sources.

The marks come from numerous sources including commercial operators, independent dive clubs, reference works, and active divers. Some are known to be accurate, while others may not be. Some GPS marks may even have come from maps using the AGD66 datum, and thus may need be converted to the WGS84 datum. To distinguish between the possible accuracy of the dive site marks, we've tried to give each mark a source of GPS, Google Earth, or unknown.
