Mary Kathleen was established in the 1950s as a uranium mining town. It was named after Mary Kathleen, the wife of the Queensland Mines Minister at the time. Mary Kathleen was primarily built to support uranium mining operations in the area. Uranium was mined there from 1954 to 1982. After the closure of the mine, the town was dismantled, and most of the infrastructure was removed or demolished. Today, only remnants of the mining facilities and some structures remain.
Today, Mary Kathleen stands as a ghost town, with remnants of buildings, mining infrastructure, and other remnants of its past. It has become a destination for tourists and history enthusiasts interested in exploring the abandoned town and learning about its mining history. Visitors can still see the remains of the town's streets, foundations, and some buildings, providing a glimpse into its past.
