The '''premier of Western Australia''' is the [[head of government]] of the state of [[Western Australia]].<ref name="Premiers factsheet">{{cite web |title=Premiers of WA Factsheet |url=https://www.parliament.wa.gov.au/intranet/libpages.nsf/WebFiles/Fact+Sheets+Premiers+of+WA+Updated+May+2021/$FILE/Fact+Sheets+Premiers+of+WA+Updated+May+2021.pdf |website=Parliament of Western Australia |access-date=18 June 2022 |date=May 2021 |archive-date=20 March 2022 |archive-url=https://web.archive.org/web/20220320102918/http://www.parliament.wa.gov.au/intranet/libpages.nsf/WebFiles/Fact+Sheets+Premiers+of+WA+Updated+May+2021/$FILE/Fact+Sheets+Premiers+of+WA+Updated+May+2021.pdf |url-status=live }}</ref> The role of premier at a state level is similar to the role of the [[prime minister of Australia]] at a federal level. The premier leads the executive branch of the [[Government of Western Australia]] and is accountable to the [[Parliament of Western Australia]]. The premier is appointed by the [[governor of Western Australia]]. By convention, the governor appoints as premier whoever has the support of the majority of the [[Western Australian Legislative Assembly]], the [[lower house]] of the Parliament of Western Australia. In practice, this means that the premier is the leader of the political party or group of parties with a majority of seats in the Legislative Assembly. Since Western Australia achieved self-governance in 1890, there have been 31 premiers. [[Roger Cook (politician)|Roger Cook]] is the current premier, having been appointed to the position on 8 June 2023.

==History==
The position of premier is not mentioned in the [[constitution of Western Australia]]. From 1890 to 1917, the premier was not an official position, rather, it was the title unofficially given, but widely used to refer, to the head of the government.<ref name="Premiers factsheet" />{{sfn|Reid|Oliver|1982|p=1}} When Western Australia became a [[self-governing colony]] in 1890, Governor [[William C. F. Robinson|William Robinson]] initially indicated he would use the title ''[[prime minister]]'' to refer to the head of the government. However, after he appointed [[John Forrest]], the title ''[[premier]]'' was used for consistency with the other Australian colonies.<ref name="Premiers factsheet" />{{sfn|Reid|Oliver|1982|p=2}} The position was first officially mentioned when the governor appointed [[Henry Lefroy]] as premier on 28 June 1917. However, when the governor designated and declared the six executive offices of the government on 2 July 1917, the position of premier was not listed, creating an ambiguity.<ref name="Premiers factsheet" />{{sfn|Reid|Oliver|1982|p=1}}<ref>{{cite web |title=Government Gazette Extraordinary of Western Australia |url=https://www.legislation.wa.gov.au/legislation/prod/gazettestore.nsf/FileURL/gg1917_029.pdf/$FILE/Gg1917_029.pdf |website=Parliamentary Counsel's Office |access-date=18 June 2022 |date=2 July 1917 |archive-date=18 June 2022 |archive-url=https://web.archive.org/web/20220618074252/https://www.legislation.wa.gov.au/legislation/prod/gazettestore.nsf/FileURL/gg1917_029.pdf/$FILE/Gg1917_029.pdf |url-status=live }}</ref> It was not until 3 April 1947 that the premier became one of the executive offices of the government.<ref name="Premiers factsheet" />{{sfn|Reid|Oliver|1982|p=1}}<ref>{{cite web |title=Government Gazette of Western Australia |url=https://www.legislation.wa.gov.au/legislation/prod/gazettestore.nsf/FileURL/gg1947_017.pdf/$FILE/Gg1947_017.pdf |website=Parliamentary Counsel's Office |access-date=18 June 2022 |page=555 |date=3 April 1947 |archive-date=7 June 2023 |archive-url=https://web.archive.org/web/20230607063258/https://www.legislation.wa.gov.au/legislation/prod/gazettestore.nsf/FileURL/gg1947_017.pdf/$FILE/Gg1947_017.pdf |url-status=live }}</ref>

The most common cause for a change of premier is an election. Since the 1990s, elections have occurred roughly every four years. Before then, elections were at most three years apart, except for during [[World War II]]. A less common cause for a change of premier is the ruling party changing its leader. This can occur as a result of a resignation, death or [[leadership spill]]. In this case, the new premier is whoever the party elects as its new leader. Another cause for a change of premier is a loss of majority support in the [[Western Australian Legislative Assembly|Legislative Assembly]]. This commonly occurred in the first three decades of self-governance, but has not occurred since 1916. If this occurs, the premier must either resign or be dismissed by the governor.{{sfn|Reid|Oliver|1982|p=3}}

==Powers and function==
The powers of the premier are set out by convention and by legislation. By convention, the premier advises the [[Monarch of Australia]] as to who to appoint as governor. The premier advises the governor as to who to appoint to [[Cabinet (government)|cabinet]] and which portfolios should be given to each cabinet minister. The premier sets out the responsibilities of ministers and the [[Act of Parliament|acts]] that they would administer. The premier leads the cabinet and chairs cabinet meetings. They communicate with the governor, the cabinet, the state government, other state and territory governments, the federal government, and overseas governments. The premier advises the governor on when state elections should be held. They oversee the [[Department of the Premier and Cabinet (Western Australia)|Department of the Premier and Cabinet]]. While premier, they stay as a member of parliament and they retain their responsibility for representing their electoral district.<ref name="Premiers factsheet" />

==Characteristics==
As of 2023, there have been 31 premiers of Western Australia.<ref>{{cite web |last1=Johnston |first1=Greig |last2=Zadvirna |first2=Daryna |title=Roger Cook to be Western Australia's next premier, replacing Mark McGowan |url=https://www.abc.net.au/news/2023-05-31/roger-cook-wa-31st-premier/102416518 |website=ABC News |access-date=4 December 2023 |date=31 May 2023 |archive-date=4 December 2023 |archive-url=https://web.archive.org/web/20231204060155/https://www.abc.net.au/news/2023-05-31/roger-cook-wa-31st-premier/102416518 |url-status=live }}</ref> [[Carmen Lawrence]], who was appointed on 12 February 1990, is the first and only woman to be premier of Western Australia.
