Cleo Smith was a 4-year-old girl from Western Australia who disappeared from a tent while camping with her family at the Blowholes campsite near Carnarvon in October 2021. Her disappearance triggered a massive search effort across land, air, and sea, and police quickly treated the case as an abduction. After 18 days, officers found Cleo alive and unharmed inside a locked house in Carnarvon, just minutes from the local police station. A 36-year-old man was arrested and later sentenced to a long prison term for kidnapping her. Cleo’s rescue was described as a miracle and became one of Australia’s most widely followed missing-child investigations.
