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.

Murrawijinie Cave lies on the Nullarbor Plain in the locality of Nullarbor, South Australia. In June 2013 it was included in the Nullarbor Wilderness Protection Area, which placed the cave and its entrances under formal protection. The hand stencils in ochre on one entrance wall were drawn by Indigenous Australians, and hawks and swallows nest in the caves.

One entrance of Murrawijinie Cave carries hand stencils drawn in ochre by Indigenous Australians. Visitors can see these marks on the wall of that entrance, which sits close to the main doline opening. The stencils are the only recorded cultural traces in the cave and are the reason to look at the walls, not just the sinkhole.

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.

Murrawijinie Cave has three entrances close together, the main one a doline, which is typical of the Nullarbor's karst topography. Hawks and swallows nest in the cave, so visitors may see birds entering and leaving the openings.
