The Nationals are meeting in Canberra as negotiations with independent MPs intensify in the nation's capital.
Nationals leader Warren Truss on Monday will lead his expanded team in the party's first meeting since the election.
Nationals MPs are pushing for a fair deal for regional people across the nation, not just in the seats of independent MPs Rob Oakeshott, Tony Windsor and Bob Katter.

Mr Oakeshott has accused the Nationals of running a smear campaign against him, but Mr Truss hosed down the claims on Monday.
Both Mr Oakeshott and Mr Windsor have questioned the coalition's tactics as both the Liberals and Labor try to broker a deal with the independents to form government.
Mr Oakeshott wants a "please explain" from Opposition Leader Tony Abbott about whether a phone call from an unnamed Liberal, who told his wife it was "the devil" calling, is part of a broader strategy to pressure him.
"If these are Rambo-style phone calls that I'm receiving from loose cannons, that's fine," Mr Oakeshott told ABC Radio on Monday.
"But what is of deeper concern is, is this a strategic move to try and destabilise this whole process?
"If that is the game, that needs to be flushed out early."
It follows reports Liberal backbencher Alby Schultz phoned and abused Mr Windsor, telling him to back the coalition in forming government.
The three independent MPs are former Nationals.
Nationals senator John Williams said his constituents deserved the same sweeteners the independents were demanding for their electorates.
"They (the Nationals MPs) are not going to sacrifice funding for projects in their electorates to simply to be put into (the) independents' electorates," Senator Williams told ABC Radio on Monday.
WA Nationals MP Tony Crook, who won the seat of O'Connor from veteran Liberal member Wilson Tuckey, will also join the partyroom meeting.
Mr Crook has refused to rule out sitting on the cross benches because of tensions between the WA Nationals and their federal counterparts.
The newly elected MP is pushing for the major parties to match the state's royalties program and pour millions of federal money into regional WA.
Prime Minister Julia Gillard has ruled out Mr Crook's early demand to drop the minerals resource rent tax, killing any chance that he will back Labor.
But he has continued to play hardball with the Liberals, saying he is not prepared to sit in the coalition partyroom.
Tasmanian independent Andrew Wilkie and Greens MP Adam Bandt will also venture to the capital to push their cases with Ms Gillard.
