What is the difference between "Parliament" and "Government"? Parliament is the entire law-making body consisting of the Governor, the Legislative Assembly (Lower House) and the Legislative Council (Upper House), although the term "parliament" is often used to refer just to the two Houses. The party or group of parties with a majority of Members in the Lower House forms the Government. The Government is led by the Premier. Members of Parliament from the Government party or parties are chosen as Ministers to be in charge of Departments of the Public Service. These Departments implement and administer the laws and policies of the Government. Members of Parliament from the largest party or grouping opposed to the Government form the Opposition.
