Nationals leader Matt Canavan has left the door open to running in Capricornia or another lower house seat at the 2028 Federal election, declaring he will “do whatever it takes”.

The Queensland Senator, who rose to the top job in March, conceded on Sunday that the next election could be his “last” acknowledging the political challenge ahead of the minor Coalition party.

The Coalition has continued to lag in public polling while Pauline Hanson’s One Nation has surged to challenge Labor’s popularity.

Mr Canavan said he had no illusions about a tough road ahead in an interview on Sunday Agenda, declaring he would contest a House of Representatives seat to protect his party’s representation.

“I’ll do whatever it takes… We’ve got a great local member there in Capricornia, Michelle Landry. I’d love to see her continue,” he told News24.

“It’s been great to see David Littleproud and Colin Boyce there going around again –great local members in Queensland.”

The seat of Capricornia is currently held by his Nationals colleague Michelle Landry — meaning she would need to step down, retire, or preselection would need to change for Mr Canavan to hold that lower house seat. Mr Canavan currently leads from the Senate.

“But if I’m required, if it is required to keep a seat, to hold one more seat in the lower house somewhere. I will do it. I’ll do what I need to do save this country,” he said.

It comes as Liberal leader Angus Taylor was questioned about the leadership ambitions of former Treasurer Josh Frydenberg who is speculated to be making a political comeback.

Mr Frydenberg, who remerged to the nation’s attention during an impassioned speech in the wake of the Bondi Beach terror attack, will next week launch a new book and air in a media blitz with major networks.

Mr Taylor dismissed questions about whether Mr Frydenberg might be using the launch of his political memoir to make a comeback during an interview on ABC’s Insiders program.

Mr Taylor insisted any aspirations for the former member for Kooyong to return was “a matter for him” and added that he would welcome Mr Frydenberg playing “whatever role he’s able to play” in helping defeat the Labor government.

“With respect to Josh, I need every good Liberal shoulder to the wheel in the lead up to the next election,” he said.

“Now, people will play different roles, all sorts of roles you can play, but we need everyone who wants to get rid of this rotten Labor government out there.

“Whether it’s just liking Facebook and Instagram posts all the way through to being a candidate, we’ll see the full range.

“But we’ve all got to mobilise, and I welcome Josh playing whatever role he’s able to play.”
