Newspoll [pdf] is out [hat tip to Oz in comments on a previous thread]. The poll, taken on Wednesday and Thursday with a weighted sample of 1328, suggests a very evenly poised contest.
Labor’s primary is 41.7 to the LNP’s 42.1. The Greens are on 7.4 and Others on 8.3. In the capital, Labor is on 42.5, the LNP on 40.1, The Greens 8.6 and Others on 8.1. Outside Brisbane, Labor has 40.9, the LNP 43.9, The Greens 6.4 and Others 8.5.
Bligh’s satisfaction/dissatisfaction/uncommitted split is 46:44:10, Springborg’s numbers are 39:49:12 and Bligh leads The Borg 53/33 on preferred premier with 14 uncommitted.
Labor has a 61% decided vote and the LNP 70%. Win expectations are 56/24 with 20 uncommittted.
UPDATE (William): Steven Wardill of the Courier-Mail offers intelligence from both parties’ tracking polling, which (assuming the reports are accurate) are telling somewhat different stories. Wardill says LNP insiders believe Broadwater, Southport and Burleigh on the Gold Coast are “too tough to claim”. On Labor polling:
Sources last night said Labor tracking showed the party’s support fought back on Wednesday night during the final TV advertising blitz but then dropped away again. The tracking apparently found the LNP was likely to win with a 60 per cent chance of a minority victory and a 40 per cent chance of a majority. Swings away from Labor were found in Gold Coast seats, including Burleigh, as well as in Mundingburra, Mansfield, Pumicestone and Everton.
However, Wardill appears to believe Labor will win Gladstone from independent Liz Cunningham. Seats he tips to fall include, but are not exclusive to, Barron River, Whitsunday, Keppel, Pumicestone, Indooroopilly, Cleveland, Chatsworth and Aspley. This comes in an article that doesn’t seem to be online in which six Courier-Mail journalists lay out their predictions, which echo the consensus by ranging from LNP minority to narrow Labor majority government (which is Wardill’s prediction, despite what Labor are telling him).
UPDATE: (Possum)
Graphporn and Monte Carlo sim time.
Adding this rather spiffy Newspoll addition to the Newspoll time series, we get the following charts of all the metrics (they’re thumbs, so just click on them to expand and place your mouse over them to see what they are)


One problem I have with these Newspoll numbers is that I can’t get the primaries to match the Two Party Preferred estimate without having 60% of Greens preferences exhaust and the remaining flow to the ALP at a rate of 70%, while the broad “Others” category exhausts at a much smaller rate of between 40% and 50% (leaving 50-60% flowing through as preferences) and giving the preference flow to the ALP from the “others” at only 40%. Not massively out, but I’d be surprised if that’s what actually happens. You can play around with the figures yourself using the Editgrid widget at the bottom of this post.
Plugging this into our Monte Carlo simulation then becomes a bit tricky. Using the breakdowns of both Galaxy and Newspoll weighted by sample size, and using the Newspoll exhaustion and flow rates, the ALP two party preferred aggregation comes in at 51.7% for Brisbane and 47.8% for non-Brisbane. If we plug that into our simulation, we get an implied probability of 66% that the ALP will win at least 45 seats, and where the most likely outcome is of the ALP winning 46 seats. That simulation includes the sampling error uncertainty of the polling aggregations. If we assume that the polls are actually 100% correct, the implied probability of the ALP winning at least 45 seats with a uniform swing and standard deviation of 4% increases to 87% and where the most likely outcome is the ALP winning 48 seats.
One of the more peculiar results in this Newspoll is the rather low Greens vote in Brisbane, coming in at only 8.6% – which suggests a swing of 2.1% away from them in Brisbane since the last election. I find that hard to believe. In terms of its impact on seats won or lost – assuming a 50% exhaust rate and a 70/30 pref flow to Labor, the difference between an average Green vote of 10.7% at the last election and 8.6% this election is to effectively knock one half a percent from the ALP TPP in Brisbane, which tonight will probably equate to 3 or 4 seats.
