Murrawijinie Cave, Limestone cave system north of Nullarbor Roadhouse, South Australia.
Murrawijinie Cave is a limestone system with three separate entrances, the main one accessed through a natural doline formation in the karst landscape. The underground passages contain multiple chambers and sections shaped by water erosion over geological time.
The cave system received official protection status in 2013 when it was incorporated into the Nullarbor Wilderness Protection Area. This recognition acknowledged both its geological importance and cultural significance to the region.
The cave walls display hand stencils in ochre created by Indigenous Australians, visible to visitors today as evidence of ancient occupation. These markings represent a direct connection to the people who lived in this landscape for thousands of years.
The cave is accessed via a signposted dirt track about 10 kilometers from Nullarbor Roadhouse that is passable by standard two-wheel drive vehicles. Visitors should wear sturdy footwear and be prepared for rougher conditions on the access road during wet weather.
The cave interior stays roughly 10 degrees Celsius cooler than the outside temperature, offering natural relief on hot summer days. This temperature difference makes the underground space a comfortable refuge during the hottest times of day.
