The ministries of Western Australia are the centre of executive power in the Government of Western Australia. They are composed of Ministers who are responsible for one or more portfolios, answer questions on those portfolios in Parliament, and control the operation and administration of departments, authorities, statutes and votes within those portfolios. In a formal constitutional sense, they possess executive power through being appointed to the Executive Council, which contains all members of the Ministry plus a Clerk, and is headed by the Governor of Western Australia who represents the Crown.
