The Shaft deaths

“The Shaft,” a sinkhole located near Allendale East in South Australia, was discovered in 1938 when a horse stumbled upon a small hole. It was later expanded to allow exploration access. In the 1960s, a local diver descended into the cave’s 17-meter-wide lake chamber, reaching a depth of 21 meters.

The cave is part of a network of deep solution features in porous limestone in the region. The main chamber spans approximately 140 meters in length and 80 meters in width, with a water level around 7 meters below ground level. A rock pile beneath the surface opening extends to a minimum depth of 36 meters. Additional tunnels reach depths of about 80 and 124 meters, respectively. Due to its size and depth, divers and equipment are lowered separately into the chamber using a hoist system.

The name “The Shaft” is said to originate from the shaft of sunlight that illuminates the depths on sunny days.

Diver Names: Stephen Millott, Christine Millott, Gordon Roberts, John Bockerman
Date: May 26, 1973

In 1938, a cave known as “The Shaft” was discovered on farmland in Allendale, near Mount Gambier, Australia. The cave remained unexplored until the mid-1960s when a local diver ventured into its depths and discovered a wide lake cave. The main cavern, approximately 460 ft (140 m) in length and 260 ft (80 m) in width, housed two tunnels that extended deeper into the cave. “The Shaft” posed unique challenges for divers as they had to be lowered separately with their equipment using a lift system.

On May 26, 1973, a team of nine divers embarked on a cave diving adventure in “The Shaft.” During their exploration, they encountered safety violations such as insufficient guidelines, lack of staging tanks for decompression, no gas management plan, and no predetermined diving buddies. Despite these violations, they proceeded with the dive.

One of the divers, Robert Smith, experienced the effects of nitrogen narcosis when he reached a depth of 180 ft (55 m) and decided to return to the surface. However, the other divers continued deeper into the cave. Glen Millott, another diver, encountered Christine and attempted to signal her to return, but she swam away. Eventually, Robert and Glen surfaced, encountering Larry and Peter. They realized that the remaining four divers were in grave danger.

Desperate attempts were made to locate the missing divers, but due to poor visibility and silt accumulation, their search proved unsuccessful. The police underwater recovery team conducted search operations but had to halt due to their diving limits. In January 1974, a television film crew using advanced lighting equipment discovered the body of Stephen Millott at a depth of 50 ft (15 m).

In subsequent months, recovery operations led to the discovery of Christine and Gordon’s bodies, found holding each other beneath a rock ledge. John Bockerman’s body was discovered deeper in the cave. However, due to murky waters and the onset of nitrogen narcosis symptoms, the recovery operation was suspended multiple times.
