Pete Michell tries his hand at Adventure Caving on the Limestone Coast. The Naracoorte Caves National Park covers an area of 600 hectares and comprises a labyrinth of caves, underground tunnels and rare fossils dating back millions of years. We go were no camera crew has ever been before - we head off the beaten path and crawl into Starburst Cave - an adventure caving experience for those that love a challenge and don't mind tight spaces!
