The Liberal and National parties are back together again after a week-long break-up over policy difference.

Liberal leader Susan Ley held a press conference with Nationals counterpart David Littleproud today, spruiking their new shadow cabinet.

"Our parties are at their best when they work together to fight, right now, as a strong opposition," Ms Ley said.

"Personally, David and I will be friends. I think a woman who got her start in the shearing sheds of western Queensland can always find something to talk about over a steak and a beer, David, with you, the person who represents those communities now."

"We’ve laid the boundaries. We’ve laid the foundation stones," Mr Littleproud said.

"There were principles that we talked about, and it took Susan and the leadership that she took over to get her party room to that position.

"And we reciprocate that. We know this is a partnership."

The parties failed to sign a partnership agreement last week over sticking points including nuclear energy, the Regional Australia Future Fund (RAFF), services in the bush, nuclear power and supermarket divestiture powers.

However, compromises between the parties have been reported in the lead up to today's announced recoupling. 

Ms Ley said the Coalition will support removing a ban on nuclear energy in Australia "as an important first step" before further policy discussion, although she said has not committed to building state-run facilities. 

The Liberals also agreed to in-principle support for the RAFF and, provided it's used as a last resort, divestiture powers against supermarkets.

Newly elected member for Parkes, Jamie Chaffey, will also take on the role of Assistant Minister for Agriculture and Natural Resources.

"This is a man of great conviction, of great work ethic," Mr Littleproud said.
