A Colossal Cave System lurking Beneath Australia’s Desert: The Nullarbor Caves

Beneath the flat, treeless expanse of the Nullarbor Plain lies one of Australia’s most astonishing hidden worlds. This vast limestone platform conceals an immense system of caves, tunnels and sinkholes formed over millions of years. From colossal chambers decorated with stalactites to crystal-clear underground lakes, the Nullarbor’s caves reveal a story of ancient seas, extinct megafauna and the remarkable power of water to carve stone.
