Koonalda Cave, Archaeological cave in Nullarbor Plain, South Australia.
The limestone formation extends for 1200 meters with two main passages connected by a high window and contains three lakes at 80 meters depth.
Aboriginal people used this cave around 22,000 years ago for flint mining activities before abandoning the site approximately 19,000 years ago.
The cave walls display thousands of square meters of Aboriginal geometric patterns and finger-marked lines dating back 20,000 years.
The cave requires prior arrangements for visits and lies 99 kilometers west of Nullarbor roadhouse, accessible primarily through private transportation.
In 2023, the Australian Government allocated 400,000 dollars to install surveillance cameras and enhance security measures following recent vandalism incidents.
