In 1988, Andrew Wight and his team went on to attempt a record cave dive in Pannikin Plains Cave on the Nullarbor Plain, where flash floods turned the expedition into a life-or-death adventure. This was captured on film by his support team, and eventually published as Nullarbor Dreaming. This short film launched his career as an international film-maker and culminated in him becoming James Cameron's right-hand man on many 3D and other film projects. Sanctum was inspired by his Nullarbor experience
