The Kilsby sinkhole is a sinkhole in Mount Gambier, Southern Australia. The naturally occurring sinkhole is used for civilian and police dive training.

History

The sinkhole is located on private property owned by the Kilby family since the late 19th century.[1] Due to insurance and liability concerns , access to the site is highly controlled.[2] Some commercial dive companies teach diving at the site, and limited recreational diving is allowed by permission.[3] The sinkhole has been consistently used to train police divers of the South Australian Police divers since the early 1980s.[3][2]

In the 1970s the site was used under contract by the Australian Government to test the Barra Sonobuoy, a classified submarine detection buoy.[4][5][6]

Diving deaths

In 1969 three divers died while diving the sinkhole.[2] In 2010 a diver died when he became entangled in a cable 37 metres below the water's surface.[7][2] Two others died diving the sinkhole the same year.[8][2]
