Queensland is governed under the Westminster system of parliamentary government. Unlike other Australian states, it is not a bicameral system, having only one elected house. This house is called the Legislative Assembly. After an election, the State Governor appoints as Premier, the leader of the party who can control a majority of the elected members in the lower house. The Premier must resign if they no longer have a majority in the Legislative Assembly. This can happen if they lose seats at an election, or if their own political party does not support them.
