Major parties are trying to emulate One Nation policies, its leader says, as two opinion polls show a plateau in voter support for the populist political force.
The latest Newspoll shows Pauline Hanson's party falling from its peak of 27 per cent to 24 per cent.
But the shift in voters has not meant an increase in support for the major parties.
Labor remains steady on a primary vote of 31 per cent, as does the coalition on 21 per cent.
Anthony Albanese remains the preferred prime minister over Angus Taylor, ahead 46 per cent to 37, with 17 per cent remaining uncommitted.
Senator Hanson said Mr Taylor's release of the coalition's immigration policy on Tuesday was only because of pressure in the polls from One Nation.
"He's picking up the vibes, and that's why a lot of people are supporting One Nation," Senator Hanson told Melbourne radio station 3AW on Monday.
"At least we're on the same page, and we want to do it.
"Will they follow through and do it? I doubt it."
While 40 per cent of voters were satisfied with the prime minister's performance, Mr Albanese had a dissatisfaction level of 57 per cent.
Mr Taylor's net approval rating has gone down, with 33 per cent satisfied and 46 per cent dissatisfied with him as opposition leader.
Under the coalition's policy, immigration levels would be reduced and those who didn't respect Australian values would be "booted out".
A Resolve poll, also published on Sunday, showed One Nation falling in support from 24 per cent to 22 per cent.
The drop has meant the coalition has overtaken One Nation as the party with the second-highest primary vote, rising from 22 to 23 per cent in the latest survey.
Labor rose by three percentage points from 29 to 32 per cent.
Mr Albanese holds a narrow lead over Mr Taylor as preferred prime minister, leading by 33 per cent to 32 per cent.
Kos Samaras, director of strategy and campaigns at polling company RedBridge said One Nation's support had clearly plateaued but it was too early to tell whether voters were turning away from the party.
"Really what we're seeing is a ceiling... the One Nation vote has stabilised in the mid-to-high 20s" he told AAP.
But the respected pollster said the Liberals and Nationals shouldn't be celebrating.
"We don't see any evidence that the coalition's making any inroads into One Nation's base," Mr Samaras said, adding the small drop of support for Senator Hanson's party had mostly gone to other minor parties and independents.
Nationals senator Bridget McKenzie said the shift in support from One Nation did not come as a surprise.
"In times of global crisis, as we're currently in, Australians rightfully look to parties of government," she told ABC Radio on Monday.
The Newspoll and Resolve surveys coincided with the Middle East war and closure of the Strait of Hormuz, which has affected global oil prices.
