Clive Palmer has vowed to bombard Australians with advertisements and unsolicited text messages in the lead-up to the federal election, and says there is "no limit" to how much money he and his companies will plunge into the campaign.

Launching a political video game which he partly bankrolled, Mr Palmer dismissed concerns about the creditors of his collapsed Queensland Nickel refinery, including former employees, as "fake news" ahead of a trial to begin in April.

The mining magnate and property developer refused to relay the cost of the massive print, radio and television advertising campaign for his revamped United Australia Party, which includes prime time slots on the major networks.

"We're spending money and we've got a lot of money to spend," Mr Palmer said. He said "of course" his firm Mineralogy was contributing to the party, as it did to his former Palmer United Party to the tune of $3.7 million in 2014-15 alone.
