Gus Lamont is a four-year-old Australian boy who vanished from his family’s remote outback property in South Australia in September 2025. He was last seen playing near the homestead, and within about half an hour he was gone. His disappearance sparked one of the largest search efforts in the state, involving police, defence personnel, drones, trackers, and volunteers scouring vast scrubland and dams. Despite weeks of intensive searching, no trace of Gus or his belongings has been found, and investigators have not confirmed any evidence of foul play. The case remains open, leaving his family and the wider community desperate for answers.
