Why did gold discoveries in Victoria affect South Australia’s copper industry?

The discovery of gold in Victoria during the 1850s caused significant economic dislocations in South Australia by diverting labor away from the colony’s existing industries. Specifically, the allure of the goldfields drew workers away from South Australia’s copper industry, leading to labor shortages that created short-term setbacks for the sector.12

Despite these challenges, South Australia remained a highly successful experiment in economic development during this period, eventually expanding its mineral base through further copper discoveries at Moonta and Wallaroo.12
