On the night of the 2023 NSW election, I along with most other observers had expected that Labor would achieve majority government.
After midnight I turned off the ABC’s predictive tools and assessed every seat solely on the votes counted. The tally I came to had Labor on a certain 45 seats, ahead in another four seats, and based on past trends had a reasonable chance of winning three seats where the Coalition was ahead on votes.
The next morning I rang the Sydney news room suggesting that news reports refer to Labor winning but step back from stating Labor had achieved a majority. On the seats remaining in doubt, you would have expected Labor would win at least two of the doubtful seats to achieve majority government. That was the position I reported on ABC news on the Sunday night.
This did not happen. Labor won only the 45 seats I had marked down as definite Labor wins on my Sunday morning check. In the four seats where Labor was ahead, and every other seat that was close, Labor went backwards with each day’s counting.
On Monday 27 March, the uncounted pre-poll centres were added to the count. A trend against Labor emerged and on the Monday evening I tweeted that Labor would probably miss out on a majority and win 45 or 46 seats. In seat after seat the addition of pre-poll votes on Monday had revealed a consistent decline in Labor’s position.
That trend went even further on the Saturday after polling day when the largest batches of postal votes were added in key seats. For the first time the Liberal Party pulled ahead in Ryde and moved even further ahead in Terrigal. Both seats had looked like Labor gains on election night.
As an election analyst, such post election night shifts set you up for criticism. You are accused of not taking into account that pre-polls and postals would favour the Coalition.
Actually, the model I use builds in a correction for postal and pre-poll voting trends. The model factors in the postal and pre-poll vote trends from the last election.
What happened in 2023 is that the 2023 pre-poll and postal vote results turned out to be very different to the election day results. The trend to the Coalition in post-election counting was much larger than in 2019.
There were also many more pre-poll and postal votes in 2023. The early vote broke more strongly for the Coalition than previously, and the impact of these votes was amplified in the final result by their greater weight of numbers.
