The great coppermining complex in the Moonta-Wallaroo-Kadina area of South Australia thrived from the 1860s to the 1920s, and became known as Australia's Little Cornwall because of the 'Cousin Jacks and Jennies' who lived and worked there. These Cornishmen, together with some Australian miners, suffered great hardships in the early days, with food and water scanty and disease endemic. As well as opening the mines they had to build their own homes, but they set to work with a will. With wattle and daub, limestone and clay, or handmade bricks they constructed snug cottages, and a number of these may still be seen.
