This election in 1913 was a regular election for half the members of the Senate held at the same time as a general election for the House of Representatives; see terms of senators. The 1913 House of Representatives results can be seen here.
Electoral system: The Commonwealth Electoral Act 1902 (No.19 of 1902) provided for plurality (first past the post) voting in each state as a multimember electoral district for the selection of senators. Section 150 provided that each voter was required to cast as many votes as there were vacancies to be filled (block voting), selecting three candidates for half Senate elections (more if there were casual vacancies). The multiple voting system for the election of of senators from 1903 to 1917 meant that the number of valid votes was much larger than the number of ballot papers cast. This voting system precludes the usual calculation of the informal (invalid) vote for these elections in the table above.
Ballot design: The design of the Senate ballot paper for the election of senators from each state was set out in Form O of the Electoral Act (Section 131). Candidates were ranked in a single list in alphabetical order of surname; no party affiliation or additional information about candidates was provided unless there were two candidates with the same name and then a geographical location was provided to distinguish them.
Parties: The results of this half Senate election in 1913 confirmed the two-party system established by the creation of the Liberal Party in 1910. While voting for the Senate showed an even balance in the support between the Australian Labor Party and the Liberal Party, the Senate electoral system produced a result that favoured the Labor Party (see Table above).
