David Littleproud has been elected leader of the Nationals, replacing Barnaby Joyce.
Perin Davey, a senator for NSW, was elected as his deputy.
Littleproud, a former agribusiness banker, has been the MP for the Queensland seat of Maranoa since 2016.
He served in the Turnbull and Morrison governments as Minister for Agriculture, as well as Minister for Water Resources and Minister for Northern Australia.
The 45-year-old has entered leadership speculation for the Nationals in the past, rising to the deputy position in 2020.
He recorded a tiny 0.3 per cent swing against him in Maranoa on May 21, but nonetheless comfortably won his race, with 72.2 per cent of the two-party preferred vote.
Littleproud is considered to be more amenable to climate policy than many of his colleagues, and while in government worked to save the Murray Darling Basin Plan and improve federal biodiversity stewardship.
He voted against legalising same-sex marriage in 2017, but stated his vote would be determined by the majority view of his electorate.
Maranoa voters sided against marriage equality with a 56.1 per cent majority.
