Former Nationals deputy leader Fiona Nash is determined to make a speedy return to the Senate, less than two months after being disqualified by the High Court.
Fiona Nash hasn't given up on taking back the Nationals' deputy leadership as she eyes a return to parliament through a casual vacancy.
Ms Nash was back in Canberra on Wednesday, flanking "bestie" Barnaby Joyce for the swearing in of a new-look ministry which has sparked fresh tensions within the Nationals.
The former NSW senator was booted out of her job in October when the High Court ruled she was ineligible to sit in parliament because she held UK citizenship.
The court's decision sent shock waves through the minor party which lost Mr Joyce and deputy leader Ms Nash on the same day.
While Mr Joyce returned after a thumping by-election victory earlier in the month, Ms Nash's path back to the upper house has been complicated with Liberal Jim Molan expected to take her Senate spot.
But she's not giving up on getting the band back together.
"If an opportunity did arise I would be very keen to come back and serve as a National Party member of the coalition," Ms Nash told Sky News on Wednesday.
Veteran NSW senator John Williams has already announced his plan to retire at the next election, but Ms Nash is hoping for a vacancy to emerge sooner.
"If there is a short-term option clearly that is something I would look at," Ms Nash said.
Since Ms Nash left parliament in October, Victorian senator Bridget McKenzie has taken over as the Nationals' deputy leader after winning a party room ballot.
Asked if she would look to be reinstated as the party's second-in-charge on her return to parliament, Ms Nash said: "It's certainly an option but that's way down the track."
Senator McKenzie's automatic ascension to cabinet has been one of the factors at play in the Nationals' current round of ructions.
Mr Joyce cited her promotion as the reason for dumping Victorian former infrastructure minister Darren Chester from the front bench and elevating little-known Queenslanders David Littleproud and John McVeigh.
Ms Nash backed that call, saying it was "untenable" for two of the party's five cabinet spots to be filled by Victorians.
Queensland MP Keith Pitt was also dumped from the ministry, prompting reports he is set to leave the party and move to the crossbench.
"The best thing he can do for the people he represents is stay with the National Party," Ms Nash said.
