The Mystery Craters are a curious geological feature on a privately run roadside property south of Bundaberg — 35 small sandstone-rimmed pits, generally about a metre across and several metres deep, set in a small area of paddock. Their origin is genuinely uncertain; the property has been working since 1971 to convert the puzzle into a small tourist attraction with cabins, a café, and a colouring-in book about the craters.
It is more curiosity than spectacle — fifteen minutes will cover it — but if you are driving south to Childers or Hervey Bay, it is on the route. Small admission. Cabins available for an overnight stop.
