Pauline Hanson claims to enjoy support from a number of coalition members "behind closed doors", despite the prime minister's belief she is not welcome in Australian politics.
The One Nation leader, who launched her Queensland Senate campaign at a Brisbane bowls club on Friday night, pledged to work with whichever leaders were elected at the July 2 double dissolution election should she win a seat.
She hit back at Malcolm Turnbull's "arrogant" statement that she is "not welcome" in Australian politics and said the comment was not reflective of the entire government.
"I have actually had text messages from other coalition members elected who actually are quite willing and quite happy to work with me," Ms Hanson told AAP.
"I'm not even going to disclose who it is, because I've given my word that it will never be revealed - I don't need to."

Pressed on the seniority of such secret supporters, Ms Hanson simply claimed to have had "quite a number" of them over the years.
"A lot support me behind closed doors but won't come out and say it," she said.
"Let's just say coalition members and we'll let it go at that and we'll see what happens after the election."
Ms Hanson, whose comments about immigration and Islam have been divisive, laughed off criticism from Greens senator Sarah Hanson-Young that her return to high office would be "a disaster" for Australia.
Political strategists say Ms Hanson has her best shot yet at a Senate seat courtesy of the double dissolution election and voting reforms, which halve the quota of votes needed to grab a spot in the upper house.
Asked whether any potential victory could be put down to circumstance, Ms Hanson said the electoral reforms meant voters now own their preferences.
"It's the voter's choice and I will respect the umpire's decision."
About 50 protesters targeted the launch and were moved into a car park by police officers.
Protester Carl Jackson said the group wanted to stand up against a "wave of racism".
"Maybe we can't stop them from being racist, but maybe we can make them too ashamed to admit it in public," he said as they jeered guests.
Several protesters secretly made their way into the club, springing up and yelling obscenities before they were kicked out ahead of the launch.
Ms Hanson, who insists her policy is not "anti-immigration" but "zero net immigration", said anyone who disagrees with her should voice it at the ballot box.
"They're wanting to stop freedom of speech, but when it doesn't suit them," she said.
"That's a shame that our country's got to that stage."
