The table above shows raw figures in the first two columns for the primary vote, then uses booth matching over the next three columns for the primary vote swings, two-party preferred result and two-party swing. However, these figures are entirely derived from the polling day booth results, and are unaffected by the 2742 pre-polls and 2946 postals which have been added to the count, which are included in the first two columns. Here the swing has been slightly lower – respectively at 16.0% and 14.7% by my reckoning, compared with the 20.3% shown based on polling booth results. So it would seem in the final analysis that the swing is unlikely to have a two in front of it. An interesting new feature of the declaration vote breakdowns is “uncertain identity”, which no doubt has something to do with the new voter identification regime. There are as yet no results listed, but presumably this will change over the next week as the ECQ investigates the declaration votes of those who showed up at the polling booth without the required ID.

The map to the right shows booth-level two-party results from both the March 2012 state election and yesterday. The swing was highly uniform throughout the electorate with the exception of the Chermside booth, where it was only about 6%, and the Prince Charles Hospital booth, where it was 31% (not shown because with only 223 votes cast it falls below the 250-vote threshold I use for inclusion). The waters in Chermside may have been muddied by the fact that it attracted voters who at the general election voted in nearby polling booths in other electorates.

The chart to the left offers some historical perspective by detailing polling booth results (so no postals, pre-polls, absents or other declaration votes) in Stafford from this and previous election. I did this half in the expectation of showing that 2012 rather than yesterday was the extraordinary result, but what emerges is that it was a very good result for Labor by any measure. It should be particularly encouraging for them that they were about 6% up on two-party preferred from a winning election in 2009, although I should caution that Labor did seem to suffer a bit of a backlash in Brisbane’s inner north on that occasion.

Another way of putting the result in perspective is offered by the chart to the right, which seeks to illustrate the extent to which by-election swings provide a pointer to the result of the next election. Drawing on federal and state by-election results over recent decades, it shows the government swing (which is usually negative) on the X-axis and the overall swing recorded at the subsequent election on the Y-axis. The linear trendline that runs through the middle is not brilliantly predictive, explaining only 42% of the variation, but the relationship is there, and for a 20% by-election swing it implies a swing of 8.7% at the following election. While this is a seismic shift in absolute terms, it still leaves the LNP out in front by 54-46. If such a swing was uniform, Labor would emerge with a still fairly modest 27 seats in an assembly of 89 – although importantly, one of those seats would be Ashgrove.


7.51pm. Stafford Heights two-party result added.

7.39pm. All that remains for the evening is two-party results from the Stafford Heights booth and perhaps a few pre-poll numbers. The projected swing to Labor is now over 20% – a disastrous result for the LNP by any standard.

7.20pm. All booths now in on the primary vote, and the result is fairly clearly looking worse for the LNP than Redcliffe, which would be gravely alarming for them.

7.03pm. At around the time I thought results would start coming in, they’re actually well on their way to finished. Preference shares: 52.1% to Labor (41.4% in 2012), 14.4% to LNP (20.3%), 33.5% exhausted (38.3%).

7.01pm. Gympie Road booth added, swing now 18.9%.

6.58pm. Stafford West booth has reported, and the swing is staying above 18%.

6.55pm. There are now enough two-party votes that I’m no longer going off 2012 preferences, and the Labor swing is now even higher – over 18%.

6.49pm. I very seriously understimated how fast this count was going to be. Six normal booths in plus a pre-poll, and the result is looking very similar to Redcliffe with a swing of around 16%. It can most assuredly be called for Labor now.

6.48pm. Chermside has reported 2PP: four votes to LNP, nine to Labor, 12 exhaust.

6.45pm. I’m doing some experimental probability calculations for my own amusement, and I presently have Labor’s win probability at 94.05%.

6.42pm. Newmarket booth added on primary vote. Whereas I only had the swing at Chermside at about 6%, being right on what Labor required, here it’s 18.8%.

6.37pm. Two-party result from Prince Charles added: of the non-major party votes, 16 went to Labor, five to the LNP, and eight exhausted.

6.33pm. A far more moderate result from the 382 votes at Chermside, where I’m rating Labor up 9% and the LNP down 3.5% – although a number of booths from 2012 aren’t in use this time, so such comparisons are problematic.

6.23pm. Only 216 votes from Prince Charles hospital booth, so quicker off the mark than I thought. The results are … interesting. My two-party preferred projection is at this stage based on the preference allocation from the 2012 election.

6.10pm. Polls have closed at Queensland’s Stafford by-election and counting is under way. This post will follow the count as the results come in, with the above table showing raw primary votes and percentages, and booth-matched two-party preferred projections and primary vote swings. This being a highly urban electorate, all the booths will be large and take a while to count, so I wouldn’t hold my breath on any results being in before 7pm.
