As the previous election was a double dissolution, half of the senators elected at that election had their terms backdated to 1 July 1982, to end on 30 June 1988. Senator terms for those contesting this election would have been for 6 year intervals starting from 1 July 1985, but the Double dissolution election of 1987 removed this necessity.

This was the last Senate election where Labor won more seats than the Coalition in the Senate, despite winning several victories in the House of Representatives since then.

• The Liberals and Nationals contested the previous election as a Coalition in the previous election, and did not do so in this election. The Coalition vote of 1983 of 38.2% was unchanged from the combined Liberal and National vote of this election.
