@ausgeo: Skull Rock formally known as Cleft Island is a small, but remarkable granite island that sits among the Anser group of islands off the southwest coast of Wilsons Promontory, Victoria, Australia. Very few people have been inside this island cave, adventurers have had to land on the top of the rock by helicopter, then they shimmied down ropes to gain entrance to the cave. Would you dare enter? 📸 @albertos.travels #ausgeo #skullrock #wilsonsprom #victoria #discoveraustralia #discoverearth
