Clive Palmer billboards 'not political'

Clive Palmer is not making a political comeback despite the former federal MP funding hundreds of billboards around Australia with the slogan 'Make Australia Great'.

The bright, yellow billboards, which feature a photo of Mr Palmer giving a thumbs up, aren't political but a call to Australians to improve the nation, a spokesman for Mr Palmer said.

"It's not a political campaign and has nothing to do with politics. He's just very patriotic and loves his country," the spokesman told AAP.
