The Shaft is a CDAA rated sinkhole site near Allendale. The hole
appeared in the middle of a paddock about 100 years ago. The
landholder tried to fill the hole with stone from the paddock but was
unsuccessful!
The shaft was the site of Australia's worst cave diving accident in May 1973 when four divers died after running out of air presumably due to disorientation from nitrogen narcosis. The site has a small (maybe 1m diameter by 3m long) entrance through
the limestone with an 8m drop into a lake of about 15m diameter. 36m or
so below the lake is the rock pile where the landowner had tried to fill
the hole in. The underwater size of the Shaft is enourmous and
despite the crystal clear water torch beams vanish into the blackness.
Photography in the Shaft is very difficult due to the sheer size of the
cave.
