Federal government figures have played down the importance of party-endorsed cards instructing people how to vote, as the coalition remains under pressure to preference One Nation last at the next election.
Prime Minister Scott Morrison has said the Liberal Party will wait until all candidates have been declared to decide on its preferencing arrangements for the poll expected in May.
