In the lead up to election night, Australian Electoral Officers actively monitor potential issues to be alert to potential deviations from the identified TCP Candidates. 18 At each polling place in every Division, after the close of polling (at 6.00 pm on polling day in the applicable time zone) and in view of the scrutineers, the Assistant Returning Officer opens the sealed envelope containing the names of the TCP Candidates and announces those names to everyone present (including the scrutineers). 19 Then, after the first preference count20, the ballot papers for the TCP Candidates for that Division are removed to a secure area and the ballot papers for the remaining candidates are notionally allocated to the TCP Candidate for whom a higher preference has been expressed on the ballot paper. The result of the allocation of ballot papers to the TCP Candidates – the Indicative TCP Count – for each polling place is telephoned to the Divisional Returning Officer for the Division. The Divisional Returning Officer progressively enters the Indicative TCP Count for each polling place into the Commission's Election Management System. The Election Management System updates a webpage on the Commission's website, "The Tally Room". 20 From the close of polls in the principal time zone of a Division, or shortly thereafter, the Tally Room displays the identity of the TCP Candidates in respect of whom the Indicative TCP Count will be undertaken and, once information about the Indicative TCP Count for each polling place begins to be received into the Election Management System, the Commission uses a "matched polling place method" to calculate a "matched polling place projection" in each Division. 21 The matched polling place projection is a prediction of the Indicative TCP Count in the Division, expressed as a "swing" in the Division since the last election. It is calculated by comparing the Indicative TCP Count in a polling place with the votes received at the same polling place in the previous election. The Commission explained, in a publication regarding the electoral process, that the "matched polling place method relies on the empirical fact that swings to or from political parties or candidates tend not to vary greatly within electoral 19 Pursuant to Electoral Act, s 274(2A). 20 See [13] above.
