Deputy Prime Minister Barnaby Joyce has condemned the Western Australian Liberal Party's unprecedented decision to preference One Nation ahead of the Nationals at the upcoming state election, a deal that is splitting opinion in the federal Coalition ranks.

Striking a different note to Liberal colleagues, former prime minister Tony Abbott agreed with the argument that One Nation leader Pauline Hanson was a "better person" today than when she was previously in Parliament but said the Nationals should be preferenced above all other parties.

While Mr Joyce described the deal as "disappointing", cabinet colleague and Trade Minister Steve Ciobosaidthe Liberal Party should put itself in the best position to govern and talked up Ms Hanson's right-wing populist party as displaying a "certain amount of economic rationalism" and support for government policy.

Mr Joyce said the conclusion "that the next best people to govern Western Australia after the Liberal Party are One Nation" needed to be reconsideredand the most successful governments in Australia were ones based on partnerships between the Liberals and Nationals.

"When you step away from that, there's one thing you can absolutely be assured of is that we are going to be in opposition," he told reporterson Monday morning.

"[WA Premier] Colin Barnett has been around thepoliticalgame a long while and he should seriously consider whether he thinks that this is a good idea or whether he's flirting with a concept that would put his own side and Liberal colleagues in opposition."

The deal will see Liberals preference One Nation above the Nationals in the upper house country regions in return for the party's support in all lower house seats at the March 11 election.

The alliance between the more independent WA branch of the Nationals and the Liberals is reportedly at breaking point over the deal, which could cost the smaller rural party a handful of seats.

"Pauline Hanson is a different and, I would say, better person today than she was 20 years ago. Certainly she's got a more, I think, nuanced approach to politics today," Mr Abbott told Sydney radio station 2GB.

"It's not up to me to decide where preference should go but, if it was, I'd certainly be putting One Nation ahead of Labor and I'd be putting the National Party ahead of everyone. Because the National Party are our Coalition partnersin Canberra and in most states and they are our alliance partners in Western Australia."

Prime Minister Malcolm Turnbull declined to criticise the deal, stating that preference deals in the state election were a matter for the relevant division who "have got make their judgment based on their assessment of their electoral priorities".

Mr Ciobo joined the Prime Minister and other federal Liberal colleagues in defending the WA division's right to make its own decisions.

"What we've got to do is make decisions that put us in the best possible position to govern," he told ABC radio of the motivations of his own branch in Queensland.

After Industry Minister Arthur Sinodinos called the modern One Nation more "sophisticated" now, Mr Ciobo also praised the resurgent party.

"If you look at, for example, how Pauline Hanson's gone about putting her support in the Senate, you'll see that she's often voting in favour of government legislation.There's a certain amount of economic rationalism, a certain amount of approach that's reflective of what it is we are trying to do to govern Australia in a fiscally responsible way.One Nation has certainly signed up to that much more than Labor."

When in government, former Liberal prime minister John Howard declared that One Nation would always be put last on how-to-vote cards.
