A large, very clear sinkhole on a working sheep farm south of Mount Gambier. CDAA members book dive slots through the CDAA; the owners also run snorkel and tour experiences and licence other operators.
Kilsby's Sinkhole sits on a family-owned sheep farm at Moorak, about 15 minutes from Mount Gambier. It is a large open sinkhole with a chamber extending off its south-western side; divers enter from a pontoon. The owners describe visibility of around 50 m on most days.
The site has an unusual history. Divers used it from the late 1950s, but recreational diving was stopped after a double drowning in April 1969, and defence researchers later used it for sonobuoy trials. Authorised civilian diving resumed in 1983 with the CDAA Research Group, and a 2007 lease widened CDAA access. Today the CDAA books timed dive slots for its members, while the landowners separately run snorkel tours and approve other dive and freediving operators.
