Clef, also known as Skull Rock, is a gran­ite island off the coast of Cape Wilsons in the Aus­tralian state of Vic­to­ria. It is part of the Anser group of three islands and is one of the most pic­turesque islands in the Wilsons-Promon­to­ry Nation­al Park.

On the west­ern side of the island is a giant cav­ern with a grassy floor. Most like­ly, it was carved by the sea over the course of mil­len­nia, when the lev­els of the world’s oceans were much high­er than the cur­rent ones. The cave is 130 meters wide, 60 meters high and 60 meters deep. From a cer­tain angle, the island real­ly looks like a skull — hence the appro­pri­ate nick­name “Skull Rock”. The cave was also used by pass­ing ships as a train­ing ground for fir­ing can­nons.

There are actu­al­ly two large caves on the west­ern side of the island. The roof of the small­er cave is about 25 meters above the sea and forms the bot­tom of the upper larg­er cave, cov­ered with soil and veg­e­ta­tion on the sur­face.

The island is vir­tu­al­ly inac­ces­si­ble to vis­i­tors, with high ver­ti­cal cliffs and no place for a boat to dock. For this rea­son, very few peo­ple have set foot on the island and explored the cave. The lucky few who did so report­ed many can­non­balls inside.

Birds, espe­cial­ly the Dark-skinned Great Cor­morant, have cho­sen Clef Island because of its inac­ces­si­bil­i­ty and lack of peo­ple. Clef Island has become their real home.
