Around 93km northwest of Wilcannia on a sealed road through remote landscapes, the compact pock-marked opal-mining town of White Cliffs is one of Australia's strangest places. Temperatures consistently soar above 40°C, and in this rugged and hostile environment, many residents have built houses underground for shelter.
To visit opal showrooms where local miners sell their finds, follow the plentiful signage, or try your luck fossicking around old diggings where interpretative signs tell White Cliffs' fascinating history. Some disused mine shafts still lie underfoot, so care should be taking when negotiating these areas.
Around White Cliffs is the traditional homeland of the Barkindji people.
