This dive starts of with barnacles on a white rock surface in the shallower waters and then gets more lush as the depth begins to vary. There's '�Double decker', a cave to explore with swim throughs sporting giant cuttlefish. The tunnels vary like cones between 6m on entrance to 16 upon exit! There are tons of nudibranchs and even fairy penguins. To get there its bets to anchor near Deco Rock where you can go through the Long Cave, Deco Rock Cave and what is known as the 'Vertical Swim Through' a structure that drops down and then heads across to exit in the sand. You can head for the cave under the cliff to your right hand side and if the excitement isn't enough the Double decker cave still awaits! You can reach this by heading south-west. This special cave is divided into two sections on top of one another that head into the cliff. They are adjoined so you can swim between them, then exit to the sand and head left back to the boat. Its advised to tour the reef edge west or east and surface on return. The marine life is abundant.
