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.
But he's ruled out doing any deals with the party on the issue.
Nationals MP Darren Chester has stressed that whatever arrangements are chosen, preferences are really a matter for every voter.
"Preferences are there for the people casting the vote to decide on themselves," he told ABC TV on Sunday.
"I mean we stand there at those booths and hand out our how to vote cards, but at the end of day the Australian people make their own decision where they go the 1, 2, 3, 4, 5, 6 down a card."
Labor has been calling on the government to commit to preferencing One Nation last.
They say that would show leadership against hate speech, particularly in the aftermath of the Christchurch massacre, in which a lone gunman opened fire at two mosques during Friday prayers, killing 50 people.
One Nation leader Pauline Hanson has called for a ban on Muslim migrants to Australia and the outlawing of some of the religion's practices.
Liberal Senator Arthur Sinodinos said it was more important for the government to focus on encouraging Australians to vote for them than on sorting our their preferences.
"I think preferences is an interesting issue, but it's a subsidiary issue to the issue of maximising our vote," he told ABC's Insiders program.
