Nullarbor Regional Reserve, Protected conservation area in South Australia.
The Nullarbor Regional Reserve is a large protected area in South Australia defined by limestone terrain containing extensive cave systems. The landscape borders the Trans-Australian Railway and adjoins other conservation zones while providing habitat for diverse native wildlife.
South Australia's government created the reserve in 1989 to protect the natural resources and diverse wildlife of the limestone landscape. This action reflected growing efforts to maintain the region's ecological balance and preserve the land for future generations.
This land holds deep meaning for the Maralinga Tjarutja and other Aboriginal peoples, whose sacred places can still be found across the landscape. The connection between these communities and the country remains central to how the reserve is viewed and managed today.
The reserve can be reached via the Eyre Highway, with settlements along the route offering accommodation and fuel for travelers. Visitors should prepare for long distances and check what activities like driving tours or walking trails are available in this remote location.
Beneath the surface lie vast cave networks that rank among the world's largest semi-arid cavern systems. These underground passages support specialized wildlife and draw the interest of geologists and natural researchers.
