Nullarbor Dreaming

The original documentary of the 1988 Pannikin Plains Expedition, Nullarbor Dreaming, is now available on YouTube:

A team of international cave divers set out on an amazing adventure to explore the mysterious subterranean waters of Pannikin Plains Cave on the Nullarbor Plain in Western Australia. Their epic underwater exploration nearly ends in tragedy when a rare cyclonic storm hit the area and a deluge of rain results in a flash flood that funnels water into the cave causing the entrance to collapse blocking the main route out of the cave. Fifteen team members are trapped below ground. This documentary is a graphic account of the expedition and their escape.

"Mt Gambier in regional South Australia is well known for its incredible sinkholes, but below the fish and yabbies sits ancient creatures waiting to be discovered.

At the Cave Diving Association of Australia’s (CDAA’s) 50th Anniversary meeting, researchers and other members are diving deep into these sink holes to discover fossils of extinct marsupial megafauna.

The dives at the Englebrechts, Gouldens and Tank caves are part of a collaboration between the CDAA, Griffith, the University of Queensland, University of Adelaide and the South Australian Museum."

"Researchers are heading into the deep in regional South Australia to uncover the secrets of the larger-than-life creatures that once roamed the landscape.

SA's Limestone Coast was once home to massive animals such as the short-faced kangaroo, which stood 2 metres tall and weighed up to 200 kilograms.

The remains of the short-faced kangaroo and other megafauna lay fossilised in a system of limestone caves the region is famous for.

A Griffith University team is focusing on the caves, including Gouldens Sinkhole near Mount Schank and Tank Cave at Tantanoola."
