July 2018 Australian federal by-elections

The July 2018 Australian federal by-elections, known colloquially as Super Saturday, were five by-elections held on 28 July 2018 to fill vacancies in the Australian House of Representatives caused by the resignations of five MPs. Three MPs of the Australian Labor Party and the Centre Alliance's sole MP resigned due to dual citizenship concerns after the High Court ruled on 8 May 2018 that Senator Katy Gallagher was ineligible to have been elected to the Australian Senate for being a dual citizen, in similar circumstances to four of the lower house MPs.
