Pauline Hanson’s Path to Australian Prime Ministership Faces Constitutional and Historical Hurdles

One Nation leader Senator Pauline Hanson has been discussed as a possible future prime minister of Australia. While the Australian Constitution only requires ministers to hold a seat in either house of Parliament, the long‑standing Westminster convention expects the prime minister to sit in the House of Representatives.

For Hanson to become prime minister, her party would need to secure enough lower‑house seats to command confidence, either by winning a majority of the 150 seats or by forming a coalition that guarantees a stable government. This would likely require her to move from the Senate to a lower‑house electorate, either by resigning and contesting a seat at the 2028 election or by arranging a by‑election. Recent polls have shown One Nation polling ahead of the Liberal‑National coalition and close to Labor, but analysts note that the major parties could rebound and that the convention of a house‑based prime minister remains a strong barrier.

The analysis concludes that, despite rising support, Hanson’s prospect of attaining the prime ministership remains unlikely in the near term due to both constitutional conventions and the practical challenges of gaining lower‑house dominance.
