The natural wonder of the sinkhole which is forged from millennia of acidic groundwater is an extraordinary thing to discover. It was created when the top of the chamber fell on the floor of the cave and it was ideal to turn it into a ‘sunken garden’. It is one of the Australia major tourist’s attractions and all those who visit Mount Gambier must visit here especially with their children.
