Day 5: If you've ever wondered what working underground would be like or how an underground mine actually works, today's your chance with the Hard Times Mine Tour, at the Outback at Isa centre. You'll get to dress in high visibility gear, take the cage lift underground, learn the history of mining, see how the tu els are formed, feel the earth rumble with the firing of the blast face and maybe even get to use a drill. Also at Outback at Isa is the Riversleigh Fossil Centre, where you'll see 30 million year old mega fauna fossils from one of the world's richest fossil fields. This afternoon, take a short drive out to the picturesque Lake Moondarra for a relaxing barbecue, a swim or perhaps a kayak. If you like fishing, then you'll want to throw in a line here, for your chance to catch the prized barramundi.
