The Constitution and the System of Government

The Australian Constitution is the legal document that sets out the basic rules for Australia's system of government. It established the Commonwealth Parliament, the High Court of Australia, and the framework for national government.

The Constitution also divides government power so one person or group does not hold all power.

PowerMain roleTest example
Legislative powerMakes and changes lawsParliament debates and votes on bills
Executive powerPuts laws into practiceThe Prime Minister, Cabinet, ministers, and Governor-General administer government
Judicial powerInterprets and applies lawsCourts and judges decide legal cases independently

The Constitution can be changed only by referendum. A change needs a double majority: a national majority of voters and a majority of voters in a majority of states.

Crown, Governor-General, and Prime Minister

Australia is a constitutional monarchy. The King of Australia is Head of State, but the role is limited by the Constitution and does not involve day-to-day government.

The Governor-General represents the Crown at the federal level. The Governor-General must remain neutral and has formal duties, including giving Royal Assent to bills, approving appointments, starting the federal election process, performing ceremonial duties, and acting as Commander-in-Chief of the Australian Defence Force.

The Prime Minister is the leader of the Australian Government. After a federal election, government is generally formed by the party or coalition with a majority in the House of Representatives, and that party's leader becomes Prime Minister.

Parliament: House and Senate

The Australian Government is also called the Federal Government or Commonwealth Government. It is made up of members of the Australian Parliament, which has two houses.

HouseOther namesMain test idea
House of RepresentativesLower House; People's HouseMembers represent electorates based on population; government is generally formed here
SenateUpper House; House of Review; States' HouseSenators represent states and territories; states have equal representation

Members of Parliament and senators consider, debate, and vote on proposed laws. A proposed law is called a bill. If both houses agree to a bill, it goes to the Governor-General for Royal Assent and becomes law.

Three Levels of Government

Australia has federal, state and territory, and local government. Some responsibilities overlap, but each level usually provides different services.

LevelCommon responsibilities
Australian GovernmentTaxation, national economic management, immigration and citizenship, social security, defence, trade, airports, air safety, foreign affairs
State and territory governmentsHospitals, health services, schools, roads and railways, police, ambulance services, public transport
Local governmentsLocal roads, footpaths, street signs, rubbish collection, parks, pools, libraries, building permits, local environmental issues

A test question may ask which level handles a service. Use the scale of the issue: national matters are usually federal, regional public services are usually state or territory, and neighbourhood services are usually local.

Courts, Police, and Juries

Courts in Australia are independent. Courts decide whether a person has broken the law and decide penalties based on the evidence before them.

Police maintain peace and order, protect life and property, and may arrest people they believe have broken the law. Police can give evidence in court, but courts decide whether a person is guilty.

A jury is a group of ordinary citizens selected from the general population. In some cases, a jury decides whether a person is innocent or guilty, while the judge explains the law and decides the penalty if there is a guilty finding.

Civic Duties to Remember

At citizenship, you pledge to uphold and obey Australia's laws. Civic duties show how citizens participate in and support the country.

Key duties include:

  • Obey Australian laws.
  • Enrol and vote in federal, state or territory elections and referenda when required.
  • Serve on a jury if called to do so.
  • Defend Australia should the need arise.
  • Pay tax according to law, which helps fund services such as healthcare, education, defence, transport, and social security.

Voting is both a right and a responsibility for Australian citizens aged 18 years or over. It is compulsory in federal, state, and territory elections and referenda, and it may not be compulsory in some local government elections.
