Secret Harbour By-Election: Prospects And Live

Secret Harbour (ALP 11.54%)
George Tree (ALP) vs Luke Herdegen (ON), Ryan Robertson (Lib) and way too many others
Cause of by-election: resignation of Paul Papalia (ALP)

CALLED (9:34) One Nation gain from Labor

Commentary (Comments scrolling up with latest first - refresh for latest comments)

Sunday 10:50 am I am not sure we'll ever see a Labor vs Liberal 2PP for this seat but I estimate that the Liberals would have won it, around 52-48 (by normal preference flows it would be around 53 but I have reduced that on account of it being a normally weak seat).  This suggests Labor would have lost this seat even without the One Nation surge.  Given that the average swing in government by-elections is around 5% an implied swing of 13.5% is high, but also Labor are coming off a still high baseline from the last election, which would account for some of it.  

With results like this there is always a lot of talk about high swings, but the 2CP swing is not meaningful as it is not the same combatants.  The swing against the Labor 2CP is what I call a pseudo-swing; both the pseudo-swing and my estimate of the 2PP swing are lower than in Rockingham 2023.

Sunday 6:00 am What has happened in the prepolls is that Herdegen has actually got a preference flow more like I was expecting for the by-election as a whole, 52.8% (which is not surprising given how strong the prepolls were on primaries for One Nation), and so the result has gone back to the high 50s, 57-43 at present, that was expected before the bad preference flows came in.  Overall now One Nation has 49% of preferences.  From the primaries I would have expected them to get about 52.7% without considering the ballot order, which would close at least a little of the gap.
