The Kilsby Sinkhole has been a fundamental part of the Kilsby family’s grazing property on the outskirts of Mount Gambier for many generations. Like many properties on the Limestone Coast, the sinkhole provided a much-needed supply of water for stock, but in recent years, it’s had a more varied life. For many years, it was used for top-secret defence purposes, making the ideal location to test underwater sonar devices used in tracking submarines.
It’s also been a favourite location for those learning to dive, including Australian of the Year, Dr. Richard Harris. We’ve all followed his amazing story and the role he and fellow award recipient Craig Challen played in the rescue of the Wild Boars soccer team in Thailand.
It was a life-changing moment for both men and to some extent, the Kilsby Sinkhole played an important part in what’s become an international story.
“I got an opportunity to jump in Kilsby with a couple of mates with a single tank doing a smaller dive,” Dr. Harris explained. “And it was just one of those days when the sun was shining and I went, ‘What have I been doing? What have I missed out on?’ So I went back and re-did all my training and from that point, I’ve been obsessed, to be honest.”
For gin lovers, it’s now a must-visit destination, with the underground water supply used in the making of Sinkhole Gin. It’s the perfect way to end a fascinating day at the Kilsby Sinkhole, located on Sisters Road just 15 minutes drive southwest of Mount Gambier.
