Premier of Western Australia

The premier of Western Australia is the head of government of the state of Western Australia.<ref name="Premiers factsheet">Template:Cite web</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 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" />Template:Sfn When Western Australia became a self-governing colony in 1890, Governor 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" />Template:Sfn 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" />Template:Sfn<ref>Template:Cite web</ref> It was not until 3 April 1947 that the premier became one of the executive offices of the government.<ref name="Premiers factsheet" />Template:Sfn<ref>Template:Cite web</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 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.Template:Sfn

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 and which portfolios should be given to each cabinet minister. The premier sets out the responsibilities of ministers and the 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. 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>Template:Cite web</ref> Carmen Lawrence, who was appointed on 12 February 1990, is the first and only woman to be premier of Western Australia. She is also the first woman to be premier of an Australian state.<ref name="Premiers factsheet" /><ref name="Carmen Lawrence parliament biography">Template:Cite web</ref> By convention, the premier is a member of the Legislative Assembly. However, the premier can be a member of either house of parliament. Hal Colebatch is the only premier to be a member of the Legislative Council (upper house). He served for 30 days in 1919, making him the shortest serving premier of Western Australia.<ref name="Premiers factsheet" />Template:Sfn David Brand is the longest serving premier, serving for 11 years and 335 days between 1959 and 1971.<ref name="Premiers factsheet" />Template:Sfn The youngest premier is John Scaddan, who was 35 years, 2 months and 3 days old when he was sworn in in 1911.<ref name="Premiers factsheet" />Template:Sfn The oldest premier is John Tonkin, who was 69 years, 1 month and 1 day old when he was sworn in in 1971.<ref name="Premiers factsheet" />Template:Sfn Newton Moore became premier after two years in parliament, the least time aside from Forrest. Tonkin became premier after almost 38 years in parliament, the most time in parliament before becoming premier.Template:Sfn The only father and son pair to have both been premier is Charles Court and his son Richard Court. George Leake, who died of pneumonia on 24 June 1902, is the only premier to have died in office.<ref name="Premiers factsheet" />Template:Sfn Moore, Philip Collier, John Willcock and Geoff Gallop are the only premiers to have resigned due to ill health.Template:Sfn<ref>Template:Cite web</ref>

Moore is the only premier to have served in the House of Commons of the United Kingdom.Template:Sfn The only premier to subsequently serve as governor is James Mitchell.<ref name="Premiers factsheet" /> George Leake, Frank Wilson, Phillip Collier and Mitchell are the only people to have been premier more than once.Template:Sfn There are currently eight living former premiers.<ref>Template:Cite web</ref> The most recent premier to die is Ray O'Connor, who was premier from 1982 to 1983 and died in 2013.<ref>Template:Cite web</ref><ref name="WAtoday 26 February 2013"/>
