Mayhem is a challenging pinnacle and reef site off Arborek Island, Indonesia, suited for advanced divers. The site features depths ranging from 7 to 40 metres and visibility between 10 and 30 metres. Strong, shifting currents and down currents are common, requiring active depth monitoring and the use of reef hooks and surface marker buoys. Divers may encounter wrasses, which are very common, alongside uncommon species such as Peacock Mantis Shrimp, Titan Triggerfish, Giant Moray, Bluegirdled Angelfish, Broadclub Cuttlefish, Indian Lionfish, Painted Spiny Lobster, Pustular Phyllidia, flatworms, Maroon Clownfish, Horned Bullfish, pufferfish, and Notodoris serenae. Sharp coral and rock present a risk of injury if currents move divers unexpectedly.

Brief your team on down current procedures before you splash, not on the surface after you have descended. Read the current direction from the boat before entry and plan your ascent around a reef hook rather than assuming you can swim against the flow.
Located on the western edge of the Dampier Strait, just off the coastline of Gam Island.
