Government in Australia is defined by our Commonwealth Constitution, the various State constitutions and the conventions of the Westminster political system. Parliaments are the supreme government and law-making body in our system. The prime minister or premier and their cabinet form the executive government and are responsible for day to day decision making. Parties shape the landscape of our political and parliamentary system. Federalism, the sharing of powers between the Commonwealth and the States, is another important aspect of Australian politics.
