A reward of more than £540,000 has been offered for information that leads to the discovery of a four-year-old girl who is believed to have been abducted from an Australian campsite.

Cleo Smith vanished in the early hours of Saturday morning in Macleod, near Carnarvon in Western Australia.

Her parents last saw her at 1.30am when Cleo asked for a drink of water. Ellie Smith, Cleo's mother, then woke at 6am to find her daughter was gone.

The front of the tent was open and investigators believe the zip to open the tent would have been too high for Cleo to reach.

Western Australia's government has announced a $1 million AUD reward (about £542,000) for information that leads to Cleo, or the arrest of whoever is responsible for her disappearance.

Land and sea search teams - involving more than 100 officers, volunteers, and army reservists - have searched the area surrounding the Blowholes campsite where Cleo went missing. Police haven't given up hope on finding her alive, but say they suspect she was abducted.

In an update on Thursday, Western Australia police said: "Given the information now that we've gleaned from the scene, the fact that the search has gone on for this period of time and we haven't been able to locate her... that leads us to believe that she was taken from the tent".

Superintendent Rob Wilde said the force imagined they would have been able to locate Cleo by now, given "the amount of resources and the detailed search" that has taken place.

Earlier this week, Cleo's mother Ellie described her daughter as a beautiful and delicate girl with "the biggest heart".

Ms Smith said: “She would never leave us, she would never leave the tent".
