In 1859, copper near Kadina sparked a mining boom on Yorke Peninsula. By 1861, traces near a wombat burrow led to the Moonta Mining Company, one of Australia's richest copper mines. Skilled workers, mainly from Cornwall, flooded Moonta and Wallaroo Mines, shaping the town. By 1870, Moonta rivalled Adelaide, its growth evident in architecture, stone fencing, surnames, and Cornish Pasties.
The Moonta Mines thrived, producing £67,000 worth of ore in its inaugural year. By 1876, the Moonta Mining Company set a historic record by paying £1 million in dividends. However, the mining era faced a decline in 1923 due to a significant drop in copper prices.
Today, the Moonta Mines National Heritage Area, spanning 320 hectares and managed by the Moonta National Trust, preserves this rich history. The Moonta Mines Museum, housed in the 1878 Model School, offers a hands-on exploration of mining life. Visitors can delve into the mining complex through the Tourist Railway and indulge in sweet treats at the must-visit Sweets Shop.
In 2021, Moonta, encompassing historic mines, Moonta Bay, and Port Hughes, proudly earned the title of South Australia's Top Tourism Town, beckoning visitors to immerse themselves in its vibrant history.
