Below is a deeper, article-style breakdown in the style you asked for.
How many seats has One Nation won?
Quick Scoop
Pauline Hanson’s One Nation has translated its rising national vote into a handful of federal upper‑house seats, but still no lower‑house seats , even after the 2025 federal election. At the same time, there are fresh state‑level shocks, especially in South Australia, where the party’s vote surge is rattling both major parties and fuelling speculation about future seat gains.
Federal parliament: where One Nation stands
At the federal level (Canberra):
- Senate seats (upper house)
- One Nation first returned to the Senate in 2016 with four senators , including Pauline Hanson.
* After subsequent elections and term expiries, the party again sits on **four Senate seats since 2025**.
- House of Representatives (lower house)
- Despite increased national support, One Nation has 0 out of 150–151 seats in the House of Representatives (no federal lower‑house MPs).
In the 2025 federal election , One Nation won 6.40% of the national first‑preference vote in the House of Representatives (almost 1 million votes), but still failed to convert that into any lower‑house seats.
In other words: a solid protest and influence vote, but still a very small parliamentary footprint at the national level.
Federal election numbers in detail
Here’s a snapshot of how One Nation has performed federally in recent elections:
| Election year (federal) | House primary vote | House seats won | Senate seats won | Total Senate seats held after election |
|---|---|---|---|---|
| 2013 | 0.17% | [1]0 | [1]0 | [1]0 | [1]
| 2016 | 1.29% | [1]0 | [1]4 | 4 | [1]
| 2019 | 3.08% | [1]0 | [1]2 (from that half‑Senate contest) | 2–4 depending on terms | [1]
| 2022 | 4.96% | [1]0 | [1]0 new (but continuing senators remain) | 2 continuing | [1]
| 2025 | 6.40% | [5]0 | [5][1]3 (from this round of Senate contests) | 4 total after 2025 (mix of old + new) | [1]
State politics: breakthrough moments and history
Historically, One Nation’s biggest seat haul came not federally but in Queensland state politics.
- In the 1998 Queensland state election , One Nation won 11 seats in the state parliament off about 22.7% of the vote, which was more than either the Liberals or Nationals at that contest.
- Those wins were spread across what had once been safe National and Labor seats , showing how disruptive the party could be in three‑cornered fights and preference flows.
That Queensland result remains the classic example of One Nation converting a protest wave into actual seats , and it still shapes how analysts think about the party’s potential today.
South Australia 2026: how many seats now?
Your question is very likely reacting to the South Australian 2026 state election , which has suddenly put One Nation back on the political front page.
Here’s what is clear from the latest reporting and analysis:
- On election night coverage, with about 30% of the votes counted , One Nation was polling around 21.1% of the primary vote statewide, even overtaking the Liberal Party in early tallies.
- Polling before the vote had One Nation in the 19–24% range , up from just 2.6% at the previous SA election, with especially strong numbers in regional seats.
However, as of the information available:
- The reporting and commentary heavily emphasise vote share and swings , not yet a final, seat‑by‑seat breakdown.
- Analysts note that One Nation is threatening several previously safe Liberal regional seats and could realistically pick up multiple lower‑house seats if preference flows fall their way, but the exact final seat count is still being firmed up as counting continues.
So, what can we safely say?
- Historically, One Nation has absolutely shown it can win multiple state seats (like the 11 in Queensland in 1998).
- In South Australia 2026 , all credible sources agree the party is having a breakout performance and is on track to win seats , especially in regional areas, but full, final seat numbers are not yet locked in in the material currently available.
Given your “how many seats has One Nation won” phrasing, the most precise, confirmed numbers right now are:
- Federal Senate: 4 seats currently held.
- Federal House: 0 seats.
- Historic state high point: 11 seats in Queensland in 1998.
- SA 2026: clear surge and likely seat gains, but specific final seat tally not yet fully confirmed in the sources available.
Why they win votes but fewer seats
Even though One Nation’s vote has risen sharply since about 2016, its seat count is capped by a few structural factors:
- Geographic spread of support
- The party’s vote is often spread thinly across many seats, especially in the federal House, which uses single‑member electorates, making it harder to top the primary vote in any one seat.
- Preferential voting and how‑to‑vote deals
- In lower‑house contests, One Nation can poll strongly but still lose if preferences from other parties do not flow to them in sufficient numbers.
- Upper‑house proportional representation
- The Senate’s proportional system lets small parties win seats with a modest share of the vote statewide, which is why One Nation’s Senate representation is stronger than its House representation.
An example: in 2025, they scored 6.4% of the national House primary vote, enough to influence preference flows and the national narrative, but still not enough in any individual electorate to win a lower‑house seat outright.
Forum‑style wrap‑up
If you were posting this as a forum answer to “how many seats has One Nation won?”, a concise, up‑to‑date reply could look like this:
As of the most recent information:
– Federally, One Nation has 4 Senate seats and 0 House of Representatives seats after the 2025 election.– Historically, at state level they’ve done better in spikes, like 11 seats in the 1998 Queensland election.
– In South Australia 2026 , they’re having a massive surge (around 21% of the primary vote in early counting) and are expected to pick up seats, but the final seat tally is still being nailed down.
TL;DR:
Nationally, One Nation currently holds four Senate seats and no lower‑house
seats , with its most dramatic historic seat haul being 11 in Queensland
in 1998 , and a fresh wave in South Australia that looks set to add new
state seats but is still being finalised in official counts.
