A pilot who was one of the first people to begin the search for missing Cleo Smith says the four-year-old was probably gone from the area long before police arrived on the scene.

Justin Borg received a desperate call from Cleo's parents on Saturday morning, pleading for him to help find a missing preschooler.

He quickly sent his Coral Coast Helicopter Services team out to search for the girl, as his group of "world-class" musterers scoured the surrounding area while waiting for police to arrive.

Borg's team spent the whole day scouring the landscape, but saw nothing that shed any light on Cleo's disappearance.

"We were just running out the block of possibilities asking 'where do we look next?'" Borg told the West Australian.

"We were pretty sure she wasn't in the area when we conducted our second search.

"When we go and search for somebody, if they are in the area you find them really quick. Especially if you are talking abnormal colours."

Borg said the pink jumpsuit that Cleo was wearing when she disappeared would have stood out starkly against the landscape.

"We flew at a height where we were just glancing over the countryside. And then when we found nothing on the broad area search, we started a more slow and thorough search," Borg said.

"We made sure we looked under every rock, every tree, and every bush with the chopper."

It has now been seven days since Cleo was reported missing from her family's tent.

Police believe the four-year-old was taken, with a task force set up to find her.

A spokesman for the Western Australian Police force told NCA NewsWire that officers believed Cleo was located somewhere beyond the campsite.

"They've searched absolutely everywhere they possibly can in that area, and they're confident that she's not within that area," the spokesman said.

"It's moved to an investigative stage, because they've done all the searching they can and there's no evidence or information to suggest she's wandered off."

The campsite where Cleo vanished a week ago has reopened to the public.

She was staying in a tent with her family at the coastal Blowholes Campground in Macleod, near Carnarvon in Western Australia's north, when she was reported missing about 6am on Saturday, October 16.

After a week of searching the rugged terrain for the young girl, police confirmed it was likely she had been taken from the tent.

The tent zip had been opened higher than Cleo could have reached. Her sleeping bag was also missing.

While the search at the campsite is over, locals and holiday-makers have been urged to remain on the lookout.

Detectives have also revealed there are still witnesses from the crime scene who are yet to come forward.

Police believe there are people who were staying at the campsite who have not identified themselves.

They are urging the mystery campers to make contact.

Police are also performing a radio blitz in a desperate attempt to gather information on Cleo's whereabouts.

A message is being broadcast across stations in West Australia imploring residents with any information to come forward to assist police.

Police are asking anyone who was within a 1000km radius of the Blowholes campsite to send through any dashcam and security footage they have.

Footage of motel check-in and communal areas, service stations, fast-food outlets and bakeries, truck stops and camping areas, children's clothing stores, pharmacies and cosmetic and camping stores are particularly important.

The police's message comes as Cleo's best friend Naya also issued a plea of her own.

Speaking to 7 News, Naya said she "misses [Cleo] a lot now she's lost".

"I want her to come back. She needs to come home because she needs to be with her family," she said.

Naya drew a picture of Cleo and wrote in a note: "Dear Cleo, can you please come back for a little while and come to my nan's. I miss you, I hope you are all right. Love, Naya."

A special task force of more than 100 officers has been formed to investigate Cleo's disappearance.

Between 10 and 20 registered sex offenders live in the Carnarvon area but police said this week that there were no suspects.

Cleo's disappearance has made headlines in countries around the world, including Britain, the US, and India.

The state government is offering a A$1m (NZ$1m) reward for information that resulted in finding Cleo, or led to the arrest and conviction of whoever was involved in her disappearance.

Anyone with information is urged to call police on 131 444 in Australia.
