A week after they failed to rein in Indi MP Cathy McGowan, who had won with a 4.36 per cent swing on last count, they had return to full-time life at home.

Mrs Mirabella said she had not made a decision on her next move and would discuss her options with her husband, Greg.

“It's school holidays and I'm just trying to organise a few activities with the kids – I haven't even thought that far,” she said.

A qualified lawyer, Mrs Mirabella joined Melbourne University as a public policy fellow between the 2013 and 2016 elections, but was based at her East Wangaratta home.

The Coalition also appointed her to the board of government-owned naval shipbuilding firm ASC Pty Ltd.

Mr Corboy was welcomed back to his day job as manager of the family stockfeed business this week with a pile of paperwork.

“I’m back into that and we’ll see what happens,” he said.

“A lot of Wodonga and Wangaratta business people really do want us to go again.”

A message to Nationals supporters thanked them for helping win 18 per cent of votes with a limited budget.

“The campaign for the 2019 federal election commenced today and we look forward to having you on board as we reclaim Indi for the Nationals,” the message stated.

But Mr Corboy said he would leave the decision on him being the 2019 candidate to the party.

He has also been touted as a contender for Damian Drum’s vacated role in the Victorian Parliament's upper house.

“I haven’t made a decision on that, it’s still up in the air,” Mr Corboy said.

“We’ll wait and see what the party and supporters want.”

In the meantime, signage on his Nationals-branded car, featuring his face and name, has been removed following the election result.

Mr Corboy praised Ms McGowan for her decision on Friday to support the Coalition with supply and confidence to help form government.

“I’m fairly confident to say Indi is a conservative electorate,” he said.
