The South Australian Fields

The discovery of major opal fields in South Australia did not come about until well after the development of the New South Wales and Queensland fields. The initial discovery at Coober Pedy came, fortunately, at a time when opal production at other major fields was declining, and so gave a great impetus to the opal mining industry. Many finds were made in the State, all around the edges of the Great Artesian Basin, but eventually only the three major fields were developed: Coober Pedy, Andamooka, and Mintabie.
