Another progressively updated post tracking late counting in seats in doubt from the South Australian election.

Thursday night
Casey Briggs at the ABC relates that a recount (presumably as distinct from a preference distribution) has ended with One Nation’s Chantelle Thomas 58 votes clear of Liberal candidate Tania Stock in Narungga, compared with 77 votes in the initial count. However, there’s no sign of this on the ECSA site or in the results feed, so my system isn’t rating this as called. MacKillop on the other hand moves to “ON GAIN” status with the publication of a preference distribution confirming a 403-vote winning margin for James Virgo over Liberal candidate Rebekah Rosser.
Wednesday night
Most seats have preference distributions now, today’s highlight being confirmation of the Liberal win in Heysen, where the Greens fell 99 votes short of demoting Labor to third place and maybe winning on their preferences, though presumably we’ll never know. As it stands, Liberal incumbent Josh Teague retained the seat at the final count by 347 votes over Labor. Labor’s win in Morphett was confirmed by a distribution that gave their candidate, Toby Priest, a 306 margin over Liberal incumbent Stephen Patterson. Labor ended up retaining Light by 787 votes, a margin of 1.6%, where my system was still giving One Nation the faintest slither of a chance because it had no way of knowing the count was in fact over.
That leaves two seats without preference distributions that my system is not yet calling for essentially the same reason, which look like being the third and fourth seats for One Nation. As noted yesterday, the Liberal candidate has conceded defeat in MacKillop, where One Nation leads the two-candidate count by 383 after one last loose end got tied up today, which is assuredly too much to be disturbed by the emergence of any anomalies in the preference distribution. Nothing today from Narungga, where One Nation has ended the count with a 77-vote lead that will win the seat unless the preference distribution turns up something like a 50-vote bundle having been put in the wrong pile.
Tuesday night
A Facebook post by One Nation candidate Chantelle Thomas says he has won the count in Narungga by 71 votes, though the media feed has no update on her 77-vote lead at the end of yesterday. There were minor changes from rechecking in Heysen, but no change in Morphett or MacKillop.
Peter Malinauskas’s seat of Croydon has become the second seat after Finniss to report a full preference distribution, and it had the Liberal candidate dropping out before both One Nation and the Greens, with Malinauskas winning over the Greens candidate at the final count by a 24.0% margin. The One Nation preference exclusion split 61.7-28.3 in favour of Labor over the Greens: a bit over 20% of these votes were Liberal first preferences that flowed to One Nation, which would have boosted the flow to Labor to the extent that these voters were following the Liberal how-to-vote card.
Monday night
One Nation gained breathing room in the final stages of the count for Narungga: a batch of polling day declaration votes broke 44-18 their way, early voting declaration votes broke 23-15, and they gained 17 votes on rechecking, increasing their lead from 26 to 77. The week-long blockage in the MacKillop count finally cleared today, shortly after Liberal candidate Rebekah Rosser conceded defeat based on scrutineers’ reports. The 5526 votes of various types that were added broke almost evenly, with the One Nation lead narrowing from 428 to 380. My system isn’t giving it away, but as in a few other cases, it no doubt would be if it did not have a conservative over-estimate of the number of outstanding votes.
What Kevin Bonham describes as a “pro-Liberal Twitter account” claims a sample of One Nation’s preference flow had 62% going to Liberal, 23% to the Greens and 15% to Labor. In the absence of any better information to go on, I have implemented these numbers in my system in place of my previous guess of 50%, 29% and 21%, which was based on federal election preference flows and no doubt failed to account sufficiently for the impact of the Liberal how-to-vote card. However, it hasn’t actually made much difference to my projection, as the balance between the Greens and Labor is little changed, and the main question is which of the two makes the final count against the Liberal. Around 5% of the vote is tied up five other candidates, and my preference estimates collectively give them a fairly even three-way split. So far as it allowing for the possibility that Labor might win, this clearly isn’t going to happen: the two-candidate count has the Liberals leading by 239 (narrowing from 288 after the addition of 491 votes of various types since Saturday), and my system is allowing for nearly 800 votes outstanding when the actual number will be either zero or very close to it.
Finniss became the first seat to report a full preference distribution, and it confirmed that independent Lou Nicholson won the seat from only the fourth highest primary vote share. The exclusion of lower order candidates, notably the Greens, was enough to push her ahead of both One Nation and Labor, both of whose preferences (though especially Labor’s) heavily favoured her, giving her a 5.2% winning margin at the last.
Sunday night
With the curious exception of MacKillop, which has been pretty much stalled for the past week, counting for the close seats in South Australia is at a stage advanced enough that serious doubt remains only about Narungga, which might provide a fourth seat for One Nation (assuming those uncounted votes in MacKillop don’t erase their 428-vote lead) or a sixth for the Liberals. There is also the theoretical chance that the Greens could sneak into the last count in Heysen and pull off a late upset at the Liberals’ expense, but those with better information than myself do not expect this. My system is not quite calling Light, though I have no doubt it would be if its read on how many votes are outstanding wasn’t erring on the high side, or Morphett, which the ABC is calling for Labor on the basis of what I assume is better information than my own.
The race in Narungga keeps getting closer, the latest stroke in the Liberals’ favour being a correction to the result of the Kadina early voting centre that cut 21 votes from One Nation’s two-candidate count, reducing their lead from 47 to 26. I am unclear if any further rechecking remains before the full preference count, or if some last batch of late-arriving postals remains to be added to the count. Polling day declaration votes were added yesterday (meaning Sunday) in Morphett, which increased Labor’s lead from 261 to 290 – this was the only vote type for which no votes had been reported, and it may be that that’s all there is. If anything remains at all, it likely amounts to less than the size of Labor’s current lead.
Aside from the resolution to the mystery of MacKillop, remaining points of interest are whether any anomalies show up in the full distribution of preferences, which I’m told will begin for some seats today, and the resolution of the result for the Legislative Council. I’ve been paying no attention at all to the latter, but looks very much like being Labor five, One Nation three, Liberal two and Greens one.
