A new coal-fired power station and a carve out for farmers from emissions reductions are the changes Nationals behind the latest leadership coup want Barnaby Joyce to fight for as Australia's new Deputy Prime Minister.

"If Mr McCormack remains in that position we are keen to keep working with him, and would also like to invite the new Deputy Prime Minister, Barnaby Joyce, to visit Benalla so he can see the two Inland Rail plans now on the table - and why we prefer the track realignment".

"I am really pleased that I leave the deputy prime ministership with the love of my life, Catherine, and the respect of our three children", he said.

McCormack had reportedly been accused by party colleagues of failing to push back against such accelerated climate action, a charged topic among the Nationals' rural conservative voters. "It is not Barnaby policy - it's Nationals policy", he said.

Mr Joyce has categorically denied the allegations calling them "spurious and defamatory". Given he (Mr Morrison) can not be here physically, I will hold that chair.

Michelle Laundry, a Nationals MP who backed the (now) former leader McCormack, said before the spill she'd had a "gutful" of the ongoing leadership chat.

WA Nationals leader Mia Davies, who has been a vocal critic of Mr Joyce, on Monday also said she was disappointed.

He stepped down from leadership in 2018 after his affair with former staffer and now partner, Vicki Campion went public.

But he said he had reflected during his three years on the backbench.

"I'm not even sure it matters for the purposes of QT though".

In Question Time on Tuesday, Labor MP for Franklin in Tasmania, Julie Collins, asked Mr Joyce how he responds to the concerns of women in agriculture.

"I will try, always, to be the better person".

"Barnaby Joyce has been elected leader of the National party at a federal level and will therefore be going through the various situations that he has to go through", Damian Drum, a whip in National party, told reporters in Canberra.

Joyce has previously said he was willing to vote against any government legislation that costs jobs as a result of higher climate standards.

"Good for him, everyone has their moments and in small towns like ours there's dirt on lots of people", Ms Murray said.
