The Limestone Coast’s underwater world has been showcased to the nation in a new documentary featuring cave diver Richard Harris.

In the documentary Mr Harris, who became world-famous for his heroic efforts in the Tham Luang cave rescue, takes viewers on a unique journey back tens-of-thousands of years inside the underwater caves where only the most trained divers can access.

Mr Harris said the caves near Mount Gambier/ Berrin offered one of the most premier diving locations anywhere in the world.

“People would drive through the Limestone Coast and have no idea what is beneath their feet – kilometres of some of the most pristine water-filled tunnels in the country,” he said.

“The opportunity for genuine original exploration still exists on this planet, and, by-and-large the only place to do that is in caves – and that’s what brings me back every single time.”

My Underwater World, which aired on Saturday, July 6, was created in partnership between Mr Harris’ film company Speleopix, 57 Films and the South Australian Tourism Commission.

57 Films is in discussions for possible international distribution, which could see the unique geography and sinkholes in the South East showcased internationally.

My Underwater World can be viewed on 9Now.
