  Coober Pedy is an opal mining centre in the biggest opal field in the world providing about 80% of the world's gem-quality opals. The town is hot and dry; the climate is classified as desert in the Koppen classification system. Average rainfall is 156 mm a year, and average maximum temperature is 28° for the year with January as the hottest month with daily average maximum temperature of 36°. To escape the heat many residents live underground. This practice is said to have been initiated by returned World War One soldiers to whom the idea of living in a cave or hole in the ground was not unusual. Now there is an underground church, shops and businesses as well as residences.
Coober Pedy is on the Stuart Highway 846 kilometres north of Adelaide. Population was 1,916 in the 2006 census. Position is 29° 00'S, 134° 46'E.
