Wonder under the paddocks

A successful prime-lamb operation lies atop the unique natural wonder of Kilsby Hole, one of the best cave-diving sites in the world.

When Graham Kilsby became the fourth generation of his family to run Bringewood, the successful prime-lamb operation in the farming district of Moorak, he also inherited a jaw-dropping natural wonder. The Limestone Coast area in the south-eastern corner of South Australia is world-renowned for its extensive subterranean network of caves and sinkholes, and a spectacular example lies beneath the Bringewood pastures. Created when the roof of an underground chamber collapsed, possibly thousands of years ago, divers rate Kilsby Hole among the world’s best cave-diving sites due to its exceptional water clarity.
“They like it because they can see somebody who’s right over the other side and it looks like they’re floating on air,” Graham says. “It’s 65 metres deep and a classic bell shape, which flares out like a football oval at the bottom, and in the middle of the day, when the sun is directly overhead, it sends down a beam of light that illuminates the entire chamber.”
