The police in Australia are searching the beach shacks along the Macleod coast for a missing 4-year-old girl, who was last seen Saturday sleeping in a tent with her family.

Cleo Smith was staying in a tent with her family at the Blowholes Campground, before going missing. Authorities launched a search for the girl after her parents woke up and found she was not in her sleeping bag inside the tent. Despite an extensive land, air and sea search, there have been no clues as to the whereabouts of Cleo, Perth Now reported.

On Monday, the police released an image of the sleeping bag, which was similar to the one she was using the night before her disappearance. 

“Cleo was last seen sleeping in a red and black sleeping bag and was wearing a pink/purple one-piece sleep-suit with a blue and yellow pattern,” the police said, according to Perth Now. “Grave concerns are held for Cleo’s safety. WA Police are exploring all possibilities and have a number of investigative resources to assist including detectives from the Homicide Squad as well as Forensics and local detectives."

“Police are searching a number of shacks today (Monday) that are located along the coastline at the campsite," the police added.

Inspector Jon Munday said an investigation was underway into the child's disappearance and they were not ruling out the possibility Cleo had been abducted.

“We are not ruling that out. We are not going to get blinkered or sort of assume that something has happened,” he told reporters, according to the Australian. “At this point in time, unfortunately, everything is still on the table.”

The girl was last seen wearing a pink/purple one-piece sleep suit with a blue and yellow pattern.

The girl's mother, Ellie Smith, on Sunday urged anyone with information about her “sparkling” daughter to call the police. Authorities have also been checking dashcams and CCTV cameras in the area.

Meanwhile, a GoFundMe page has been set up by local man Bill Kent to help Cleo’s family and the search efforts. As of Monday morning, the page raised more than $38,000.

“A well respected family of our community has had a very traumatic experience with the disappearance of their eldest child,” Kent wrote.“The land, sea and air search has been extensive, with everybody involved putting in an amazing effort to help locate Cleo.”
