Police have visited a number of homes in North Plantations, about 5 miles from Carnarvon along the North West Coastal Highway, in search of the four-year-old.
The reason for the visits has not been made public, but police are gathering new information every day in their investigation.
Drone searches were also conducted again at Blowholes – a campsite popular with locals over the weekend – where Cleo was last seen.
Cleo Smith’s mother Ellie has continued her prayer on social media to help bring her daughter home.
Ms Smith also posted a photo of missing persons, asking everyone with information to contact police.
Detective Inspector Rod Wilde of WA Police’s Major Crime Division said yesterday that police had received some questions about police response the day she was reported missing.
He confirmed that Mrs Smith first called police shortly before noon. 06.00 local time on 16 October.
Two police cars arrived at the blowholes not long after 7 p.m., he said.
Family friends arrived after 8 a.m. to help with the search, and police set up a roadblock just after 8:30 p.m.
Officers later requested drone and SAS assistance, and at 11 a.m., detectives from the Major Crime Division were deployed.
Superintendent Wilde said there was nothing unusual in the length of time between police arrival at the scene and the roadblock being set up.
“Obviously, the first police officers had to determine what had happened,” he said.
Superintendent Wilde said cars were searched at Carnarvon Blowholes all day after police arrived and that on-site visitors were helpful to police.
He said it is a possibility that Cleo had been missing for hours when police were first called.
