Pauline Hanson's One Nation is the most popular political party in the country, a survey suggests.
A Redbridge Group/Accent Research poll, published on Monday by The Australian Financial Review, shows support for One Nation has risen four points to 31 per cent.
Labor's primary vote is at 28 per cent, down three points since the poll firm's last survey a month ago and the government's budget that was announced on May 12, and the coalition dropped two points to 20 per cent.
Support for the Greens dipped one point to 12 per cent and backing for the "other" category of parties rose two points to nine per cent.
Labor leads One Nation 51 per cent to 49 per cent on the Redbridge poll's two-party-preferred basis, calculated by asking respondents how they would direct their preferences.
