The Nullarbor Plain of southern Australia is one of the most barren, bleak landscapes on the planet. But underneath this flat wasteland is an intricate system of deep subterranean caves and underwater channels. The Nullarbor is consisted of the largest contiguous block of limestone in the world, and over the course of millions of years, water erosion has carved out this awe-inspiring labyrinth of caves. Not only is it amazing that such vast reserves of water lie underneath this arid landscape, but cave-divers have recently made surprising discoveries about water temperature that may hold new clues about the formation of these geological marvels. Taking refuge from the scorching Australian desert sun, Anja Taylor, Simon Pampena and Dr Derek Muller go underground to explore the largest of the Weebubbie caves.
