WA search continues for missing 4yo girl

A desperate search will continue into the night for a four-year-old girl who has gone missing from a campsite in rural Western Australia.

Cleo Smith was last seen about 1.30am on Saturday at the Blowholes campsite on the coast at Macleod, north of Carnarvon.

The girl was wearing a pink one-piece sleepsuit with a blue and yellow pattern when she was last seen.

A full land search is under way and police say they won't scale back efforts until last light.

Some land resources will continue the search overnight before the rescue mission resumes at first light on Sunday with the aid of marine and air assets.
