2018 Longman by-election


A by-election for the Australian House of Representatives seat of Longman took place on Saturday 28 July 2018, following the resignation of incumbent Labor MP Susan Lamb.
In early counting, within an hour of the close of polls, the Australian Broadcasting Corporation's psephologist Antony Green's electoral computer had predicted Labor to retain the electorate with an increased margin.
The Liberal National Party's failure to win this seat for the ruling Coalition has been cited for the downfall of Prime Minister Malcolm Turnbull almost a month later on August 24.

Background

Due to the High Court ruling against Senator Katy Gallagher on 9 May 2018 as part of the ongoing parliamentary eligibility crisis, Lamb and three other MPs in the same situation announced their parliamentary resignations later that day, while the Perth incumbent resigned for family reasons. The Speaker announced on 24 May 2018 that he had scheduled the by-elections to occur on 28 July 2018. Popularly labelled "Super Saturday", the occurrence of five simultaneous federal by-elections is unprecedented in Australian political history. The others are:
Mark Latham, Labor leader between December 2003 and January 2005, voiced a robocall authorised by Pauline Hanson, in an attempt to discourage Labor voting and instead encouraged minor party voting.
