There are reportedly 22 Climate 200-backed independents running for seats in the House of Representatives and Senate.
Mr Holmes a Court says there are no strings attached to the $8 million offered in support of the candidates’ campaigns.
Mr Priestly did not accept funds from the Climate 200 organisation, which is focused on ousting Liberal-held inner-city members in the seats of Wentworth, North Sydney and MacKellar in NSW and Goldstein and Kooyong (held by Treasurer Josh Frydenberg) in Victoria.
Entering the final two weeks of campaigning for the seat of Nicholls, Mr Priestly hit national headlines on May 10 on ABC national news program Afternoon Briefing.
Mr Priestly fielded questions on where his allegiance would lie in the event of a hung parliament or minority government.
He was also quizzed on the source of funding for his campaign.
Afternoon Briefing host Greg Jennett described Mr Priestly as “testing the nerves” of the Coalition candidates in Nicholls.
Mr Priestly said he was running to ensure Nicholls received its fair share of services and infrastructure.
“There has been certain amount of neglect, stemming from Nicholls being such as safe seat,” Mr Priestly said.
Independents, including Mr Priestly, could be influential in a minority government scenario and at the very least, he said, Nicholls constituents would be “no worse off”.
“I can act on issues important to people, that the other candidates will be dictated to by party politics,” he said.
Mr Priestly, in responding to questions about campaign funding, said all his financial support had come from people or businesses that had a meaningful relationship with the seat of Nicholls.
“We have rejected funding offers from people and organisations outside of the seat,” he said.
“I am absolutely committed to this community and I want people to be really confident about my motivations.”
