Q: It may look like a run-of-the mill paddock, but beneath the surface lies a breath-taking phenomenon. Situated 450 km southeast of Adelaide is Mount Gambier, one of the few places in the world with the water conditions and soft limestone bedrock that give rise to spectacular underground sinkholes. Stunning images show specialist divers exploring otherworldly sites such as the 65 metre deep Kilsby’s Sinkhole and the 120 metre deep Shaft, which lie below seemingly mundane farms and paddocks. The caverns are the epicentre of The Cave Divers Association of Australia, who navigate the sites in the name of science. ‘Most people are drawn to the sport for the challenge and exploration, but they become passionate about the scientific elements afterwards,’ said John Vanderleest, the national director of the Cave Divers Association of Australia.Mount Gambier is one of the few cities in the world with the right conditions for underground sinkholesIt features spectacular sites like Kilsby’s Sinkhole and the The Shaft, which are found below paddocksThe caverns are among 30 identified cave sites used by the The Cave Divers Association of AustraliaCave diving involves rigorous training to explore elusive caves using specified gear and equiptment
