Kilsby Sinkhole is a world-renowned sinkhole that draws divers from all over the world due to its crystal-clear waters. The dive site is located on private property in the South East of South Australia and features a few swim-throughs with limestone walls.
Visits can be pre-arranged through approved operators, and trained and student divers can come visit the sinkhole.
Most divers only have access to areas with direct vertical access to the surface, while those with specialized training can enter the overhead environment.
Kilsby Sinkhole has a depth of over 60 meters (197 feet), but diving is generally not permitted below 40 meters (131 feet).
