Pauline Hanson says she will represent anyone who assimilates into Australia if she becomes prime minister after One Nation eclipsed Labor in a poll to become the most popular political party in the country.
The proportion of people planning to put One Nation first on their ballot paper has risen four points to 31 per cent, according to a Redbridge Group/Accent Research poll.
Angry voters seeking a candidate who will upset the status quo are turning to Senator Hanson's populist right-wing movement in large numbers, Redbridge director Tony Barry said.
"There is a very pessimistic outlook amongst voters and that is pushing them towards an anti-establishment candidate or party as their wrecking ball and their truth-teller," he told AAP.
Labor's primary vote is at 28 per cent, down three points since the polling firm's last survey a month ago and the government's budget released on May 12.
