A by-election to elect the next member of the Australian House of Representatives in the electorate of Cook was held on 13 April 2024, following the resignation of sitting Liberal member and former Prime Minister Scott Morrison.[1]
Morrison's resignation was first announced on 23 January 2024, and came into effect on 28 February 2024.[2]
Liberal candidate Simon Kennedy succeeded Morrison as the new member for Cook. It was the fourth federal by-election to have taken place since the first sitting of the 47th Parliament.
Cook encompasses much of Sutherland Shire in Sydney's southern suburbs. It was first contested at the 1969 Australian federal election and named after naval captain and explorer James Cook. It has been held by the Liberal Party for all but two terms, the lone exception being 1972-1975 when the Australian Labor Party held the seat. The Liberal margin swelled in the Coalition's 1996 victory. Since then, Cook has been one of the safest Liberal seats in metropolitan Australia.
During the 2021 Australian census, Cook's median age of 42 exceeded both the national (38) and state (39) medians. In the realm of economic indicators, the median personal weekly income in Cook amounted to $991, surpassing the corresponding figures for the state and nation, which stood at $813 and $805 respectively. Additionally, the demographic composition of the electorate saw over 60 percent identifying their ancestry as English or Australian.
