Ripper is a current-prone boat dive on the eastern side of Cocos Keeling that rewards divers who are comfortable planning a drift. The site is built around a large coral mound with a sand chute and a sloping hard-coral wall, so the dive stays interesting even before the current kicks in. When the current is running, the plan becomes a true drift with boat pickup, and the appeal is the fish action: big-eye trevally, reef sharks, and the broader Cocos pelagic scene.
