When can the Next Federal Election be Held?

On Twitter recently, the most frequent question I am asked is when “can” the next federal election be held. Second place goes to when “will” the election be held.

This post attempts to answer both questions.

The three-part answer on “when can” the election be held is –

  • The first date for a normal house and half-Senate election is 7 August 2021, if announced this weekend and writs are issued by Monday 5 July.
  • The last date for a normal house and half-Senate election is 21 May 2022. This date gives six weeks to complete the complex Senate count and allows Senators to be declared elected and start their terms on 1 July. A mid-May election would be announced in early April 2022.
  • There is a highly improbable option for a half-Senate election by 21 May 2022 and a separate House election as late as 3 September 2022.

The short answer on “when will” the election be held is –

  • when the Prime Minister thinks his government has the best chance of winning, or
  • if prospects look grim, the last possible date.

Party Vote by Vote Type – 2018 Victorian Election

Back with another graph of the day post.

Every election held in Australia post the arrival of Covid-19 has seen a sharp decline in voting on election day and a surge in postal and especially pre-poll voting.

Last October’s Queensland election saw only 27.6% of votes cast as within-district polling day votes, with 43.6% of votes cast as pre-polls and 23.8% as postal vote. (See this post)

March 2021 saw a similar surge in Western Australia with polling day ordinary votes falling to 38.0% compared to 40.2% for pre-poll votes and 14.8% as postal votes. (See this post)

At the November 2018 Victorian election, polling day ordinary votes represented only 48.3% of all votes, the first Australian state election where less than half of votes were cast on the day in district. The rate of Early/Pre-poll voting was 36.8%, then the highest recorded at an Australian election, having quadrupled in 12 years.

Given the trend to voting before polling day has been stronger in Victoria than anywhere else, and given the state’s experience with Covid-19, one can only guess how low the rate of polling day voting will be at the 2022 state election.

The graph below shows the percentage vote by vote type at Victorian elections since 2006.Read More »Party Vote by Vote Type – 2018 Victorian Election

Analysis of Preference Flows at the Upper Hunter By-election

The NSW Upper Hunter by-election on 22 May was notable for the unusually low first preference vote for the two major parties. The Nationals polled 31.2%, Labor 21.2%, with the combined vote for the other 11 candidates an unusually high 47.6%.

The by-election was conducted under NSW’s optional preferential voting rules and 63.4% of other candidate ballot papers exhausted their preferences before reaching one of the final two candidates. At the end of the count, exhausted ballot papers represented 30.2% of the first preference vote.

With ballot paper data from the by-election now published, it is possible to examine more closely the two-party preferred flows of preferences from excluded candidates, to determine how many preferences voters completed, and to measure the influence of how-to-vote recommendations on preference flows.Read More »Analysis of Preference Flows at the Upper Hunter By-election
