Mr Joyce revealed the new-look cabinet five days after being sworn in following his shock return as the leader of the Nationals. He rolled Mr McCormack in a party room vote last Monday.

The new deputy prime minister has taken on the portfolios of infrastructure, transport and regional development, stripping Mr McCormack of his ministries.

Supporters of Mr McCormack also took a hit, with the Member for Parkes Mark Coulton losing the regional health portfolio and Darren Chester, the Member for Gippsland, removed as veterans affairs minister.

The member for Calare, Andrew Gee, has instead been rewarded with Mr Chester's title, and Lyne MP David Gillespie collecting the regional health role.

Mr McCormack posted a message of support to his fellow dumped MPs early last night.

"[Darren Chester and Mark Coulton] have fulfilled their ministerial roles admirably, earning the wide and enduring respect of all they have served," he tweeted.

"They will continue to put the regions first and representing their communities diligently and strongly. Thanks to both of you for your efforts."

Senator Bridget McKenzie was among the winners in the shuffle, being promoted to regionalisation, regional education and regional health minister. She will also take on deputy leader David Littleproud's old portfolio of emergency management as he serves as minister for agriculture and northern Australia.

The new ministers are expected to be sworn in on Friday.

Mr McCormack's office was contacted for comment.
