Coober Pedy, is the world's opal capital where you can noodle for opals and keep what you find, or buy them from a selection of over 30 gem shops!  Whilst here you can experience the novelty of this underground town, from the beautiful underground church to staying overnight in an underground hotel!  Play golf on a course without grass and discover the landscapes beyond: the ochre hills of the Breakaways, the barren Moon Plains and the 5300km Dog Fence, the longest fence in the world.
