Some discussion on Twitter in the wake of the Queensland result inspired me to consider the possibility that right-wing preference flows might yet deprive Labor of a third seat in Western Australia, a result that would appreciably weaken the new government’s hand in the Senate.
The answer is that they could if preferences indeed behave as they did in Queensland, which I have illustrated with one of two new sheets on my Senate projection spreadsheet, identified as “WA — Qld prefs”. This is because a strong flow of preferences to One Nation would give them an even chance of passing the third Liberal to make it to the final count, at which point One Nation would take the last seat on Liberal preferences. However, since One Nation got less than half the vote share in WA that they did in Queensland, it seems intuitively likely that they will also get a weaker flow. I have also included the same exercise using preference flows from South Australia, identified as “WA — SA prefs”, where the parties’ vote shares more closely resembled Western Australia. This too suggests One Nation has a strong chance of making the final count, but in this case they would fall well short of taking the seat from Labor.
It should be noted here that there is a dramatic difference between the strong preference flow to One Nation upon the LNP’s exclusion in the Queensland example and the weak flow upon the Liberals’ exclusion in South Australia — partly for the reason just noted, but also because the Liberal how-to-vote card in South Australia did not recommend a preference to One Nation, whereas the LNP card had them second. Western Australia is an intermediate case in this respect, since the Liberal card directed preferences to One Nation in nine seats but not in the other six. But in the event that minor party preferences flowed to One Nation only as strongly as they did in South Australia — and assuming this was still enough to put them ahead of the Liberals and into the final count — the flow to One Nation upon the Liberals’ exclusion would have to be fully as strong as in Queensland for them to then overhaul Labor, which hardly seems likely.

The fifth Senate button press has just been conducted in Queensland, and it’s the first that relates to a result that I considered in any way in doubt. As I thought highly probable but not quite certain, Pauline Hanson has held her seat at the expense of Amanda Stoker, the incumbent third candidate on the Liberal National Party ticket. The other seats have gone two LNP (James McGrath and Matt Canavan), two Labor (Murray Watt and Anthony Chisholm) and one Greens (Penny Allman-Payne). I’ll have more to offer on this when the preference distribution and ballot paper data are published.
Most interesting of those still to come is Victoria, where the last seat promises to be a very tight race between the incumbent third Liberal, Greg Mirabella, and Ralph Babet of the United Australia Party (a lot more on that here), which the AEC announces will happen at 10am on Monday. New South Wales, which looks certain to be three Coalition, two Labor and one Greens, will be conducted half-an-hour earlier. Still no word yet on Western Australia, which looks like Labor three, Coalition two and Greens one. No word yet on when those might be expected.
UPDATE: The Queensland Senate distribution is now up on the AEC site. It turned out that Amanda Stoker was not seriously in contention: when the exclusion of Legalise Cannabis left three remaining candidates chasing two seats, Stoker held 10.3% of the vote against 14.2% for Pauline Hanson and 13.9% for Labor’s Anthony Chisholm, who were duly elected in that order. Hanson substantially outperformed my projection based on 2019 preference flows, which only got her to 12.1% compared with 14.2% for Chisholm, with Stoker on 10.9%. This is perhaps consistent with what was seen in South Australia, where preferences among right-wing minor parties were tighter this time with less leakage to the Coalition. As noted in the previous post, this suggests Ralph Babet has a solid chance of poaching the last seat in Victoria from Greg Mirabella, contrary to what my model was suggesting.
