Over The Horizons: 2025 Final Week Rolling Poll Roundup

 2PP Aggregate: 52.48 to ALP (-0.4 since Saturday)
With One Nation adjustment 51.85 to ALP
Rolling most recent released 2PP poll by each firm average 52.47 to ALP

All polls are believed to have released their final poll

If polls are accurate, Labor wins, probably with a modest majority (approx 80 seats)
If the normal range of polling to result relationships applies, Labor remains very likely to win, but majority status is touch and go
Historically, Labor has on average slightly underperformed when leading in final week polling

-------------------------------------------------------------------






Welcome to my rolling coverage of the final week of national polls.  I may write a separate article about seat polling if time permits though I'll mention some briefly in this piece.  The headline section will be continually updated with aggregate scores through to the end of the week, and the weekly reading graph will also be updated if anything much changes.  There will probaby be another roundup on Friday night or Saturday post the final Newspoll. On election night I will be doing live blogging at the Guardian and links will be posted here to the coverage when known.

Federal Election 2022: Pollster Performance Review

In 2019 the Australian polling industry had a disaster after decades of reliability - every final poll had the wrong two-party winner, the final polls were bizarrely clustered around the same wrong result, many final polls were individually wrong by more than their claimed margins and the lack of transparency in the industry was such that it was difficult to understand just why it had happened.

Fortunately 2022 has not been a repeat.  The fallout from 2019 saw a great increase in polling transparency, especially via the formation of the Australian Polling Council (though unfortunately not all pollsters have been on board with that) and also more diversity in polling approaches.  No one poll has ended up nailing the remarkable results of this year's election, but collectively, federal polling has bounced back and done well.   This is especially so on two-party-preferred results, where a simple average of the 2PP figures released in the final polls is pretty much a bullseye. The primary vote results were a little less impressive.

Here I discuss polling in several categories.  Overall YouGov (which does Newspoll) made the most useful contributions to forecasting the result, Redbridge's performance in publicly known niche polling during the campaign was very good, and Resolve Strategic's final poll was a useful counterpoint to Newspoll.  The other major polls were so-so on the whole, and many minor pollsters were wildly inaccurate.

Poll Roundup: 2022 Seat Poll Sludgefest

This is the second part of what was at first intended as a single roundup, and deals with seat polls and seat betting.  Any new seat polls will continue to be updated on this page until election day while a seat betting update will probably be added to a final roundup tomorrow night.

As a general comment, 2022 has seen a major change in the election seat polling landscape.  At previous recent elections, published seat polls were dominated (in public attention if not always in numbers) by major national players - YouGov, ReachTEL, the old Newspoll and so on, or at least by specialised pollsters who were distant from campaigns (JWS).  Often the seat polls still sucked.  In 2013 they skewed to Coalition on average (some firms more than others), in 2016 they were under-dispersed and in 2019 they did well at picking winners but badly when they sat on the fence (and they also skewed to Labor).  But at least they were neutral attempts by pollsters with skin in the national game.  

At this election YouGov has so far given seat polling the flick and instead switched to its MRP model (discussed too briefly in a previous edition).  The seat poll landscape has been dominated by uComms (a union-connected pollster with simplistic weightings and an ordinary recent track record), Redbridge (another campaign-focused pollster with often weird methods decisions and a remarkable ability to detect UAP voters), and to a lesser extent Utting Research and KJC/Telereach, neither of whom have had much public testing and the first of which is not an APC member, with publication of details rarely exceeding a single media article.  The overwhelming method of seat polling has been robopolling of often already saturated seats (one voter in Swan this week told me they'd been polled seven times).  Moreover, the two most commonly seen pollsters have been mostly conducting internal and campaign-adjacent polls rather than media-commissioned polls.   The seat polling landscape has been dominated by strategic or incidental releases of polling for campaigning purposes - mostly fed to journalists to get publicity and (in the case of teal independents in some seats) try to exploit strategic voting arguments.

Poll Roundup: Ghosts of 1996 and 2007 Edition

2PP Aggregate: 54.1 to Labor (+0.9 since last week)
(Weighted for time only, no house effects or quality weightings)
If the normal range of polling to result relationships applies, Labor is very likely to win

I've been very time-challenged this election (expending much of last night refuting an American know-all and sundry reply-guys about our preferencing system on Twitter probably didn't help) but finally, maybe, I can get something out in time for an article about the state of national polling. 

As an overall summary, Labor suffered alarmingly rapid losses in support during the first week and a half of the campaign as documented in the previous edition, but the Coalition's position did not improve over the next two weeks, and now in the latest round of polling there has been a bit of a blowout.  Labor's lead is so large now that the Coalition is extremely unlikely to win by normal means.  What hope remains for the current government is that the polls are even more wrong than last time (despite everything some of them have done to repair it) or that they are about or nearly as wrong as last time and the government makes some improvements over the final week and a half then gets lucky with the seat distribution and scrambles back, perhaps with a sub-50 2PP.  It's not all over yet, but on the other hand the prospect of a decisive Labor win is much stronger now than it looked even three weeks ago.
