Electoral system: For Senate elections from 1984, changes were made to the design of the Senate ballot paper which gave the voter the opportunity to mark a single party box which had the effect of ranking all the candidates contesting the election in the order preferred by the party whose box had been marked. This above the line voting was provided in addition to the previous system in which a voter had to rank all candidates on the ballot in the order preferred by the voter. This change in ballot design led several Independent candidates to contest Senate elections as a 'group' so that they could benefit from above the line voting. For this reason, Senator Harradine from Tasmania is shown as representing the Brian Harradine Group in the Senate even though he was elected as an Independent at the 1983 Senate election.

Brian Harradine Group: See previous note.

Nuclear Disarmament Party: The candidate from the Nuclear Disarmament Party elected to the Senate from Western Australia at this election was Josephine Vallentine. Senator Vallentine was subsequently elected to the Senate from Western Australia as leader of the Vallentine Peace Group in 1987, and as a member of Greens WA at the 1990 election.

Liberal Country Party (NT): In the national summary for this election for the Senate, the seats held by the National Country Party include the seat won for the Country Liberal Party in the Northern Territory.
