Dutton appoints Taylor as shadow treasurer

Mr Dutton, who was unopposed as leader in his party room last week after losing government on May 21, said his 24-strong cabinet will include 10 women.

"What you're seeing in this lineup is some fresh faces, we have incredible depth of talent," he told reporters in Brisbane on Sunday.

Sussan Ley, who was also unopposed deputy Liberal leader, will be spokeswoman for industry, skills and training, and also women.

Mr Dutton said former foreign minister Marise Payne had asked not to be part of the cabinet but was persuaded to take the role of shadow cabinet secretary.

Former attorney-general Michealia Cash becomes spokeswoman for employment, Karen Andrews is spokeswoman for home affairs, a role she held in government, while Jane Hume becomes finance spokeswoman.

Western Australian MP Andrew Hastie joins the frontbench as defence spokesman and Alan Tudge will take on education.

Nationals leader David Littleproud said there would be six people from his party on the coalition frontbench.

Barnaby Joyce - who Mr Littleproud defeated in a vote for the leadership last week - will become veteran affairs spokesman, while another former Nationals leader, Michael McCormack, will be spokesman for international development for the Pacific.

Kevin Hogan will also become trade and tourism spokesman.

Earlier, Mr Littleproud declined to say what was in the agreement between the Liberal and Nationals parties that form the coalition.

"It's all about policies and you'll see those policies that we enact," he told ABC's Insiders program.

"You don't ask to get underneath the closed doors of the left or the right of the Labor Party, I don't think you need to be in the policy discussions that the Liberal Party and the National Party has."
