Australia is a federal parliamentary democracy and constitutional monarchy composed of three spheres of government: the Commonwealth (federal) government, six states, two self-governing territories, and 537 local governments. The Australian Constitution establishes a federal system in which legislative powers are divided between the Commonwealth and the states, while residual powers remain with the states. Since Federation in 1901, Australia has evolved into one of the world’s most decentralized federal systems in constitutional terms, although fiscal relations are characterized by a significant degree of vertical fiscal imbalance, with the Commonwealth government raising a larger share of public revenues than it directly spends. Intergovernmental relations are shaped by extensive cooperation and coordination among governments through a range of formal and informal mechanisms, including National Cabinet and intergovernmental agreements. Australia’s multilevel governance system combines constitutionally protected state governments with a strong tradition of local self-government operating under state legislation.
