The Amazing 2026 South Australian Election: Final Lower House Results And Poll Performance

SA 2026 ALP 34 (+5) Lib 5 (-9) ON 4 (+4) IND 4 (-)
(Changes from pre-election/notional; Labor gained two seats from Liberal during 2022-6 term)

Estimated 2PP ALP 57.89 vs Liberal (+3.3)

Estimated "Shadow 2PP" ALP 58.19 vs One Nation

The 2026 South Australian lower house was remarkable in so many ways.  It makes Queensland 1998 seem almost boring by comparison, except that Queensland 1998 was there first.  Maybe all elections are going to be like this now and this soon will not seem so unusual but if that's so my colleagues and I are going to have a very busy time in the future!

All manner of curious things happened here.  Finally, someone (Lou Nicholson in Finniss) won a state or federal seat from fourth on primaries; hooray we have lived to see it.  Both majors missed the 2CP in Stuart and Mount Gambier in the first such cases since Nicklin 2001.  The Liberal Opposition missed more 2CPs (29) than they made (18) and were outpolled by One Nation (unprecedented) but are still the Opposition.  Worse than that they missed nine 3CPs as well and even managed to finish fifth in Port Adelaide and Black - Black being a seat they won at the previous election!  And so on.  It was obvious this was going to be a very messy election - a little while out I thought how on earth will we ever make a pendulum from THIS - but aspects of it were even more unique than I saw coming.

Poll Roundup: What Do We Do With A Split Coalition ... Or A Rampant One Nation?

2PP Aggregate 53.5-46.5 to ALP (-1.3 since end of 2025, +0.6 in two weeks)

Shadow-2PP Trend Estimate 54.3-45.7 to ALP vs One Nation.  One Nation has made accelerating gains.

Labor would easily win an election "held now", probably losing several seats

The last few weeks have been remarkably messy ones for Australian politics- and poll-watchers.  Following the Bondi massacre the Opposition pressured the Government to recall parliament as soon as possible to pass measures in response, only to end up wedging itself when it got what it asked for, with the result that the National Party has again broken away.  So should analysts and pollsters still treat these parties as the same entity, and if we don't, what especially do we do in the case of Queensland where Liberal and National party room members run in separate seats under the Liberal National banner?  In the meantime, One Nation has exceeded the ex-Coalition's total in three of the ten polls released so far this year and tied it in two others.  An election right now would make Queensland 1998 look somewhat orderly, with all manner of messy multi-way seats and probably One Nation making fifty or more 2CPs with perhaps something like twenty wins - though this stuff is very hard to model.  So is it time for a Labor vs One Nation "two party preferred" figure as well?
