The Liberal Party will put far-right senator Fraser Anning's party last on how-to-vote cards in almost every electorate across Australia.

Senior cabinet minister Mathias Cormann says Senator Anning's Conservative Nationals would be last except in seats which had "even worse" candidates running like white supremacist Jim Saleam at the May 18 federal election.

Senator Cormann told Sky News on Friday that other than that Fraser Anning is last in all of our seats.
