The 1973 Mount Gambier Cave Diving Disaster “The Shaft”

In todays video we’ll dive into the 1973 Mount Gambier Cave diving tragedy.

The 1973 Mount Gambier cave diving accident was a scuba diving incident in 1973 at a flooded sinkhole known as "The Shaft" near Mount Gambier in South Australia. The incident claimed the lives of four recreational scuba divers: siblings Stephen and Christine M. Millott, Gordon G. Roberts, and John H. Bockerman. The four divers explored beyond their own planned limits, without the use of a guideline, and subsequently became lost, eventually exhausting their breathing air and drowning.
