On 16 October four-year-old Cleo Smith was camping with her family. During the night she woke up and asked for a drink of water. Ms Smith checked on her other daughter, Isla, who was sleeping separately, then went back to bed. A few hours later she woke up to give Isla a bottle and saw that Cleo had gone. Her red sleeping bag was also missing. It is a very harsh environment, with limited freshwater. If she wandered off and is still in the area, there are grave concerns for her survival. Investigators are now imploring people across Australia to keep their eyes peeled for her, as another scenario is abduction. Marine and sea-based searches, mounted section officers, helicopters, drones and local Aboriginal bush trackers have all been deployed to help locate Cleo. The police are determined for a positive outcome, saying that they are ‘throwing everything’ at the effort.
