A by-election for the Australian House of Representatives seat of Mayo took place on Saturday 28 July 2018, following the resignation of incumbent Centre Alliance MP Rebekha Sharkie. [1]
In early counting, within an hour of the close of polls, the Australian Broadcasting Corporation's psephologist Antony Green's electoral computer had predicted Sharkie to retain the electorate with an increased margin. [2]
The by-election occurred on the same day as four other by-elections for the House of Representatives, colloquially known as Super Saturday.
Due to the High Court ruling against Senator Katy Gallagher on 9 May 2018 as part of the ongoing parliamentary eligibility crisis, Sharkie and three other MPs in the same situation announced their parliamentary resignations later that day, [1] while the Perth incumbent resigned for family reasons. [3] 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. [4] The others are:
Liberal candidate Georgina Downer deleted her Twitter account on 13 June 2018, claiming that trolls had been attacking her with bad language, with counterclaims from Twitter users that she had deleted legitimate policy questions posted to her Facebook account. [5]
Historically, the rural seat of Mayo has been a comfortably safe Liberal seat in two-party terms, though over the past two decades, the Liberals in Mayo had been repeatedly left vulnerable by several strong election results from minor parties and independents. Mayo was represented by Liberal candidate Georgina Downer's father, Alexander Downer, for the first 24 years of Mayo's 34-year history. [6] Further back, others in the Downer family including a Premier of South Australia represented overlapping geographical areas, in the federal seat of Angas and the state seats of Barossa and Encounter Bay.
