Nationals MP Anne Webster has publicly declared her bid for the deputy leadership of her party.
Dr Webster's declaration came ahead of the Nationals' meeting in Canberra on Monday to spill the positions of leader, held by Barnaby Joyce, and David Littleproud's deputy role.
The MP for the Victorian seat of Mallee, a former social worker and non-profit executive, received a swing of more than 4 per cent in her favour at the federal election.
Apart from her Victorian colleague Darren Chester in the seat of Gippsland, it was the highest swing achieved by any of the Nationals on Saturday.
Mr Chester is weighing up whether to challenge Mr Joyce for the leadership.
Former leader Michael McCormack and Mr Littleproud are also understood to be interested in the top job.
Mr Joyce has said he would nominate even if there was a challenge, noting his party had held all of its seats at the poll.
The Nationals automatically spill the leadership after an election.
