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.
