The One Nation party claims it inspired American conservative politician Sarah Palin's bus tour of the US.

Party members say Ms Palin was influenced by controversial redhead Pauline Hanson in launching her "One Nation" campaign tour.

One Nation NSW president Richard Putral told The Age that a party member from the Northern Territory had met Ms Palin in the US, where they exchanged political ideas.

"It just developed from there," he said.
