Rolling National Poll Roundup: 2022 Final Days

2PP Aggregate: 53.5 to Labor (-0.6 since last week) (not a prediction)
Cross-poll average of polls released in last week: 53.0 to Labor 
(Weighted for time only, no house effects or quality weightings)
If the normal range of polling to result relationships applies, Labor remains very likely to win, probably outright
Historically, Labor has underperformed when it has leads in final week polling

This article covers national polling since the update from mid last week and House of Reps federal polls will continue to be added until a final roundup which I intend to post overnight on Friday following the final Newspoll.  The aggregates and averages in the heading will be updated as new national polls come out. (Ipsos is expected, I am not sure if there will be another Morgan, while the Resolve was described as "final" by Latika Bourke.)  I aim to issue a seat polling and seat betting roundup tomorrow, and Senate polling will soon be updated on my Senate prospects page. 

In the last two days three polls have pointed to some narrowing in Labor's lead, but all this has done so far is put Labor back in about the same position as it was in after the gaffe-ridden opening week and a half, reversing minor gains since.  All four polls out this week have shown smaller leads for Labor than their previous offerings, but only in the case of Resolve is the change substantial, and Resolve is hard to take completely seriously on account of its forced-choice methods and overly high Green vote.

Poll Roundup: Are Budget Bounces Ever Real?

Aggregate: 52.7 to Labor (+0.2 in two weeks since last completely pre-Budget reading)
Labor would easily win election "held now"
Voter budget ratings are historically about average

Commentary around the 2017 federal budget has been even more focused than normal on one of the Australian beltway polling obsessions, the idea of a "budget bounce".  The Coalition's moves on the National Disability Insurance Scheme and the announcement of a bank levy, in particular, were seen as bold moves to seize the middle ground from Labor in an attempt to make the Government popular again.  Some even saw this as a threat to Bill Shorten's leadership of the Labor Opposition.

That at least a temporary bounce was widely anticipated (and also widely seen as the aim of the game) is one thing, but another has been the common blight of house-poll myopia in which commentators from particular stables obsess over the single-poll-to-single-poll changes in the poll their network commissions, while ignoring both the aggregated cross-poll trend and even the longer history of their own poll.  In the case of Newspoll, it didn't help the Government that their previous result (48-52) was a shade on the friendly side of the recent run of polling, thus setting a pretty high benchmark for any budget bounce to be assessed by News Ltd scribes from.

Poll Roundup: The Wobbles Just Got Worse

2PP Aggregate: 51.8 to Coalition (-1.1 in a week, -2.5 in five weeks)
Coalition would win election "held now" with substantially reduced majority

Just over a week ago I noted that the Coalition had an attack of the February wobbles, a common pattern of government polling tanking around this time in an election year.  A shock Newspoll result this week has seen this get a lot worse, as the Turnbull government looks rattled and tired and above all confused about its own tax reform steps, and for the first time in a long time, Bill Shorten has a spring in his step.  A robotic spring, true, but a spring nonetheless.  Government polling seems to be in freefall and no-one really knows where the bottom might be if it doesn't snap out of its tax funk sometime soon.  I've started a Not-A-Poll for anyone with a view on when or whether in this term Labor might get its nose in front.

Poll Roundup: Shorten's Latest Shocker - Or Was It?

2PP Aggregate: 53.8 to Coalition (updated to 53.4 on 1 February)
Coalition would win election "held now", probably with increased majority.
(Newspoll update added at bottom 1 February)

Pollsters are gradually emerging from their summer hibernation and over the next few weeks we will get a clearer picture of how the Turnbull Coalition government is placed as it kicks off the election year.  I am not sure exactly when Newspoll will emerge but enough data have come out in the last few weeks to make some quick comments about the overall state of play.  The 2PP estimate above will be updated and any further comments added tomorrow night following Essential, but it never alters the picture all that much.

So far this year we've had two Morgans, one Essential and one ReachTEL.  Morgan and Essential were the most strangely behaving polls late last year, with Morgan showing a massive swing to the Coalition immediately following the replacement of Tony Abbott with Malcolm Turnbull, but Essential showing a much more modest change that other posters soon stopped replicating.  Anyway the first Morgan was 55.5% two-party preferred to the Coalition by last-election preferences while the second was 54% (the closest since just after Turnbull was installed - and this off primaries that would normally have been good for only 53%).  Last week's Essential reading was just 51% to Coalition.  The Morgan had a 15% primary for the Greens, which I'm certainly not taking seriously.

ReachTEL: Liberals Narrowly Holding In Bass And Lyons

ReachTEL: Bass Liberal 51% 2PP (-3 since election) Lyons Liberal 53.2% 2PP (+2) (2PP estimates mine)

Analysis: Poll consistent with other polls showing small net swing to Labor in Tasmania, but not clearly sufficient for seat gains

The Examiner has commissioned a ReachTEL of the marginal Tasmanian federal seats of Bass (LIB, 4%) and Lyons (LIB, 1.2%) (see report here).  At this time the full data are not available online but they are present in the paper edition, albeit in a slightly garbled form.  The format of the polling is also unusual and requires some further discussion.  The poll has been reported as showing that Andrew Nikolic (Bass) and Eric Hutchinson (Lyons) would have been "comfortably returned" in an election held on Thursday.  My analysis agrees with the "returned" but disagrees about the "comfortably".

Nelson Legislative Council polling (Updated)

 (Note: for more on the Legislative Council elections see my rampagingly popular if somewhat sprawling candidate preview article.  And there is so much more to come, perhaps including a look at the dreaded Section 159!)

UPDATE: Following the publication of partial results of another ReachTEL on Tasmanian Times this article now includes discussion of two separate polls.  The second is discussed at the bottom of this article.

-------------------------------------------------------------------------------------------------------------
There have been some mysterious media reports of a Nelson Legislative Council ReachTEL poll.  I now have a copy of the full results (though there is a suggestion that an official corrected version may exist too - see first update below).  This is one of perhaps as many as four polls and surveys of the electorate conducted by or circulated among candidates; one of the others is discussed below.

The publication of partial details of polling commissioned by unknown sources in the mainstream media is a source of continual frustration because it means that the public are not in a position to know what the polling really says, or to access fully informed discussion of what the polling really means.  Nor are they in a position to be aware if there are errors in the polling results, as is apparently the case this time around.

I am here publishing the full details for the purposes of non-profit critical review and study.  Anyone thinking of copying these details for profit-related or any other purposes should be aware that the poll is copyright ReachTEL and obtain appropriate permissions.  I should note that while I have the data, I don't have permission to disclose (or know with absolute certainty) the identity of the commissioning source, and results should be treated with caution for that reason.  That said there is absolutely nothing in this poll, beyond some errors in the presentation of the data discussed below, that I have any reason to doubt is true.
