One Nation leader Pauline Hanson has lost her position as the country's preferred prime minister, with her latest polling slide ending what proved to be a brief time at the top.

Hanson's fall from the preferred PM spot marks the continuation of a downward trend in her public support, according to the latest polling figures. The One Nation leader had only recently climbed to the top of the preferred prime minister rankings, making the reversal a notable moment for the minor party and its prospects.

The development is a significant setback for Hanson, whose support base had shown enough strength to temporarily elevate her above the leaders of Australia's major parties in voter preference surveys.
