<Li> Section 156 (1) of the CEA says: "The date fixed for the nomination of the candidates shall not be less than 10 days nor more than 27 days after the date of the writ". Twenty - seven days after 8 September 2019 is 5 October 2019 . </Li> <Li> Section 157 of the CEA says: "The date fixed for the polling shall not be less than 23 days nor more than 31 days after the date of nomination". Thirty - one days after 5 October 2019 is 5 November 2019, a Tuesday . </Li> <Li> Section 158 of the CEA says: "The day fixed for the polling shall be a Saturday". The Saturday before 5 November 2019 is 2 November 2019 . This is therefore the latest possible date for the lower house election . </Li> <P> A South Australian seat will be abolished due to national population shifts which have occurred since the state's last redistribution in 2011--although South Australia's population is still increasing, faster increases in other states will see a reduction in South Australia's representation from 11 to 10 seats in the 151 - seat House of Representatives . South Australia only relatively recently experienced this twice, with Hawker being abolished in 1993, followed by Bonython in 2004 . South Australia held a state - record 13 seats between the 1984 enlargement of parliament until 1993 . For almost a century beforehand, only one single - member seat had ever been abolished in South Australia, Angas and Angas' earlier incarnation . South Australia is the least - populated state where the current number of seats can decrease, as Tasmania's current representation is the minimum guaranteed by the Constitution . </P>
