Resource & Infrastructure
The state has a diversity of significant mineral resources. As elsewhere in Australia, gold mining dominated in the late 19th and early 20th centuries. Important discoveries at Gympie, Mount Morgan, Ravenswood, Charters Towers, and Croydon stimulated population growth and infrastructure investment, providing foundations for subsequent regional development. However, earlier gold booms were overshadowed by the spectacular mineral boom of the late 20th century, with coal mining leading the way. There are also copper-lead-zinc and bauxite mines of world significance and a considerable variety of other minerals.
