Australia's Three Tiers of Government Explained

Understand how federal, state, and local government work in Australia — essential knowledge for the citizenship test section on Government and the Law.

Australia has a unique system of government with three distinct tiers, each with its own responsibilities and powers. Understanding how they interact is essential for the Government and the Law section of the citizenship test.

The Three Tiers

1. Federal (Commonwealth) Government

The federal government is based in Canberra and is responsible for matters that affect the whole of Australia. Its responsibilities include:

  • Defence and national security
  • Foreign affairs and immigration
  • Customs and border protection
  • Income tax and social security
  • Medicare and pharmaceutical benefits

The federal Parliament consists of two houses: the House of Representatives and the Senate. For a bill to become law, it must be passed by both houses and receive Royal Assent from the Governor-General.

2. State and Territory Governments

Australia has six states (NSW, Victoria, Queensland, South Australia, Western Australia, Tasmania) and two mainland territories (ACT and Northern Territory). State and territory governments are responsible for:

  • Schools and hospitals
  • Police and emergency services
  • Roads and public transport
  • Land management and planning

3. Local Government

Local councils are the third tier, responsible for community-level services such as:

  • Rubbish collection and recycling
  • Local roads and parks
  • Building approvals
  • Libraries and community centres

The Constitution

The Australian Constitution (1901) is the founding legal document that sets out the powers of the federal government and protects states' rights. It can only be changed through a referendum — a vote by the Australian people — and requires a "double majority": a majority of all voters nationally, AND a majority of voters in at least four of the six states.

The Role of the Governor-General

Australia is a constitutional monarchy. The King of Australia (currently King Charles III) is represented in Australia by the Governor-General. The Governor-General performs ceremonial duties and has reserve powers, but in practice, the elected government runs the country.

Who Can Vote?

Voting in federal and state elections is compulsory for all Australian citizens aged 18 and over. You must enrol to vote when you turn 18. This is one of the key responsibilities that comes with citizenship.
