Government Structure
How the nation is governed-the shape of power, who holds it, and the checks that constrain it-within the ordered-liberty frame and Bill of Rights supremacy described in Foundational Values.
Key Takeaways
-
Australia today is a federal parliamentary constitutional monarchy with Westminster-style fusion of executive and legislature; the new model is a federal republic with strict separation of powers.
-
The 1901 Constitution is hard to amend and lacks a comprehensive bill of rights; the proposal is a plainly written supreme constitution with an entrenched Bill of Rights and a defined (still demanding) referendum process.
-
Parliament would stay bicameral but the executive could no longer sit in either house; the Senate would gain real confirmation power over senior appointments.
-
States, territories, and local government are reframed around subsidiarity and explicit constitutional protection for local government against unilateral abolition by states.
-
Judicial review, fixed-term or good-behaviour judges with Senate confirmation, and non-delegation of core legislative power aim to make checks on power structural rather than conventional.
-
The permanent administrative state-agencies, commissions, and departments that outlast any elected government-would be brought under genuine democratic control through at-will senior appointments, mandatory agency reauthorisation, narrow mandates, transparency, and a constitutional principle that no institution may claim authority independent of the elected branches that created it.
ποΈ System of Government
ποΈ System of Government
Australia is a federal parliamentary constitutional monarchy: the Crown is head of state, while the Prime Minister and Cabinet exercise executive power subject to controlling the House of Representatives.
ποΈ System of Government
A federal constitutional republic with sovereignty in the people: a directly elected President is head of state and head of government within strict constitutional limits, appoints a Cabinet, and no executive may sit in the legislature-a genuine separation of powers.
π The Constitution
π The Constitution
The Commonwealth of Australia Constitution Act 1900 (UK) founded the federation on 1 January 1901; amendments need a double majority referendum, and only 8 of 45 proposals have passed in over 120 years.
π The Constitution
A new, modern, plainly written constitution is the supreme law of the land: every statute, regulation, and executive act must conform or be void, with an entrenched Bill of Rights, a defined referendum threshold, and plain-language drafting.
π¦ Federal Parliament
π¦ Federal Parliament
Bicameral federal parliament: the House of Representatives (151 members, preferential voting, majority forms government) and the Senate (76 senators, proportional representation) as a house of review.
π¦ Federal Parliament
Still bicameral, but separated from the executive: House originates revenue and appropriations; Senate has equal state representation and confirms senior judicial and executive appointments; no executive may hold a seat in either chamber.
ποΈ State & Local Government
ποΈ State & Local Government
Six states and two self-governing territories each have their own constitution, parliament, and courts; local councils sit under state law (planning, roads, waste); no federal constitutional recognition of local government.
ποΈ State & Local Government
The constitution embeds subsidiarity (states keep powers not delegated to the federation), requires state constitutions to conform to the federal Bill of Rights, and gives local government explicit constitutional recognition and protected autonomy over local affairs.
βοΈ Separation of Powers
βοΈ Separation of Powers
The Constitution assigns roles to legislature, executive (Governor-General on ministerial advice), and judiciary, but Westminster practice fuses executive and legislature, weakening separation compared to presidential systems.
βοΈ Separation of Powers
A strict separation of powers on a republican model: legislature makes law without delegating core authority; President and Cabinet enforce law independently; courts interpret with long terms or good behaviour, Senate confirmation, and explicit judicial review-with checks and balances so no branch dominates.
π’ The Administrative State
π’ The Administrative State
A permanent public service of over 150,000 federal employees, plus dozens of independent agencies and commissions, exercises vast regulatory, investigative, and quasi-judicial power-while ministers cycle through portfolios every few years and lack the institutional memory, staffing, or legal tools to direct the machine they nominally control.
π’ The Administrative State
The elected executive has genuine constitutional authority to direct, reorganise, and reduce the bureaucracy; senior officials serve at the pleasure of the President; every agency exercising significant public power requires periodic parliamentary reauthorisation; and no institution of government may claim authority independent of the elected branches that created it.
