Mr McCormack travelled to Mr Christensen's Dawson electorate twice a fortnight during the caretaker period ahead of last year's federal election.

The Air Force VIP flights took place just weeks after Mr Christensen was labelled the 'Member for Manila' in national headlines for spending more time in the Philippines than in Parliament.

Press reports and social media posts show that Mr McCormack attended Mr Christensen's campaign launch in Mackay on April 28 as well as announcing a $6.5 million community hub and $10 million for Lakeland Dam.

Mr McCormack previously visited Dawson on April 15 to announce $10 million for Urannah Dam.

He also opened the campaign office for the Nationals candidate for Cowper and campaigned in Tweed Heads with Nationals candidate for Richmond.

A spokesperson for Mr McCormack said the flights were used to maximise his ability to meet commitments as Deputy Prime Minister and a cabinet minister.

"During the election campaign, the Deputy Prime Minister traveled tens of thousands of kilometres and on many days visited several different electorates," the spokesperson said.

"The Deputy PM's commitment to regional Australia saw him criss-cross the country, visiting almost every state and territory during April and May 2019."

"To maximise available time and to meet commitments with community members, groups and stakeholders around the nation in his capacity as Deputy PM, Minister for Infrastructure, Transport and Regional Development, Special Purpose Aircraft are often the most effective option.

"George Christensen was emphatically endorsed by the people of Dawson, as were all 16 incumbent Nationals MP last year, each returned to Parliament by their communities."

Earlier this week The Daily Advertiser reported that Mr McCormack spent $1.2 million on private flights in the second half of 2019 and on Friday put it to the 'pub test' with patrons at The William Farrer Hotel.

Tim Wilson, from Wagga, said he was more concerned with policy outcomes.

"Bosses get paid good money to make good decisions, and my problem is that good decisions that move the city forward are not being made," he said.

Shaun Forrell, from Wagga, was more inclined to blame the system.

"The private jets are there and it doesn't matter if it's you or me using them, they are going to get used. It is what it is. The system has got to change." he said.
