Mr Anning, who once ran the Sunshine Coast solar installation business Pacific Solar and Heating, once warned of the dangers of climate change in a Sunshine Coast Seniors newspaper advertorial. The paid editorial said greenhouse gases, carbon emissions and conserving energy were "all subjects about which we are concerned today” and promoted government rebates for solar hot water systems.

Mr Roberts has been an outspoken critic of climate science, claiming it was "manipulated" by NASA, the CSIRO and others as part of a global conspiracy.

Fairfax Media attempted to contact Mr Anning, who no longer works for Pacific Solar and Heating, on Friday. While those attempts were unsuccessful, Mr Anning did issue a media statement and there was little love lost for Mr Roberts in its content. "This (High Court) outcome vindicates Pauline Hanson's decision to refer the issue of Malcolm Roberts' citizenship to the High Court," he said. "It is, however, infuriating that the Australian taxpayer has had to stump up millions of dollars to pay for a court decision, just because five polticians couldn't get their act together to do what was required by the constitution. "I can certainly assure all Queenslanders that before I nominated I took all steps to ensure that I was eligible to be a senator and, obviously, as a candidate for an Australian nationalist party, not being a foreigner is a pretty important part of that."

Mr Anning also took aim at One Nation leader Pauline Hanson's recent praise of Mr Roberts. "I fully understand that in recent weeks Pauline needed to express public support for Roberts as long as he occupied a Senate spot, however that naturally changes with the High Court decision," he said. "I have given Pauline unqualified loyalty and supported her for more than 20 years, so naturally I expect this to be reciprocated if and when I am declared elected." Mr Anning's candidate bio on the One Nation website said he had worked in the hotel industry in Gladstone for the past five years and he has reportedly worked in marketing and plane building. Meanwhile, experienced former senator Mr Bartlett, who was in Parliament from 1997 until 2008, said he expected to be formally serving as a Greens senator within two weeks.

“I can move in at very little cost, whereas if I had to set up in Cairns or Townsville with 20 months left to serve in the term, it would cost taxpayers a lot of extra money, frankly. “It’s nothing against north Queensland, we would love to get up there, but it is not justifiable at this time.” Mr Bartlett praised Ms Waters' service and said the Greens still believed that many of the claims around the Adani coal mine would be exposed. “There are many, many people in regional Queensland who believe that Adani is a con and there is no one else in the Parliament from Queensland who is definitely against Adani,” he said. “We need to have that voice magnified and just properly represented.”
