Shark!

Shark! takes a group of high-profile Australians out of their comfort zones, putting them through a series of shark-related challenges designed to test their courage, resilience and push them to their mental and physical limits.The stakes rise with each escalating task, taking them from the safety of a cage to a daunting, open-water swim with one of the ocean's most formidable, feared and misunderstood apex predators, the tiger shark.
