Sons of Gwalia was a gold mining company based in Western Australia, primarily known for its operations in the historic Leonora region. Founded in the late 19th century, it played a significant role in the gold rush era, contributing to the economic development of the area. The company was named after the Gwalia mine, which was one of the richest gold mines in Australia. In 2004, Sons of Gwalia faced financial difficulties and went into administration, leading to one of the largest corporate collapses in Australian history. The company's assets were sold off, and its legacy remains a topic of interest in discussions about mining and corporate governance in Australia.
