To understand Australian public finance, it is not enough to look at any one level of government in isolation. Australia’s fiscal structure is not simply a matter of the federal, state and local governments each collecting their own money and spending it separately. It is a highly divided, yet highly interconnected, system. The federal government has the strongest revenue-raising power. State and territory governments carry the heaviest burden of direct public services. Local governments maintain the infrastructure closest to land and community life. What holds the whole country together is a web of GST distribution, specific-purpose grants, local government assistance, and social security transfers.
The central feature of Australian public finance is vertical fiscal imbalance. This means that the level of government with the greatest capacity to raise revenue is not the same level of government that carries many of the most expensive spending responsibilities. The federal government has the strongest tax base, especially through personal income tax, company tax, GST, excise, customs duties, visa charges, and resource-related taxes. State governments also have taxing powers, but they rely mainly on payroll tax, stamp duty, land tax, gambling taxes, insurance duties, motor vehicle charges, and resource royalties. Local governments have an even narrower revenue base. Their main source of income is rates, which function broadly like a local property-based charge, along with waste charges, water charges, development application fees, parking fees, facility charges, developer contributions, and grants from higher levels of government.
This creates the basic pattern of Australian public finance. The federal government functions like a national fiscal centre. It collects large-scale revenue and redistributes it across the country through welfare payments, healthcare funding, defence, education, debt interest, grants to the states, and infrastructure investment. State governments operate as the main delivery layer of public services. They are responsible for hospitals, public schools, police, courts, prisons, public transport, roads, TAFE, public housing, and a large range of social services. Local governments are the spatial and community maintenance layer. They look after local roads, parks, waste collection, libraries, community centres, planning approvals, drainage, swimming pools, sports grounds, and local environmental management.
From the federal government’s perspective, revenue is highly concentrated. In 2026–27, the federal government is expected to receive around A$798.1 billion in total receipts, of which about A$737.1 billion will be tax receipts. Personal income tax remains the largest source, expected to reach about A$382.4 billion in 2026–27. Company tax is expected to contribute around A$154 billion. GST is expected to contribute around A$103.2 billion. Excise and customs duties together are expected to contribute around A$40.6 billion. Taxes on superannuation funds, visa charges, the bank levy, resource rent taxes, and other revenue sources make up the rest. This structure shows that the real base of Australian federal finance is not resources, and not real estate, but wages, company profits, and consumption. Resource prices matter because they affect company tax and royalties, but they are not the sole foundation of the federal budget.
Federal spending is also quite clearly structured. The largest area is social security and welfare, which is expected to account for about 37.1 percent of total federal expenses in 2026–27. This includes the Age Pension, disability support, the NDIS, family payments, unemployment support, carer payments, and veterans-related spending. The second-largest area is health, at about 16.4 percent, including Medicare, PBS medicine subsidies, aged care, and federal support for state hospital systems. Education, defence, debt interest, and revenue assistance to the states are also major parts of the federal budget. In other words, the federal government is not mainly the government that repairs local roads, collects rubbish, or runs the daily affairs of ordinary public schools. It is better understood as the national revenue collector, welfare payer, health funder, defence provider, and interstate fiscal equaliser.
The position of state governments is more complicated. They do not have personal income tax or company income tax. Those two large taxes sit with the federal government. Yet state governments are responsible for some of the most expensive and fastest-growing services, especially hospitals, schools, transport, policing, and justice. Their own revenue comes mainly from several sources. The first is payroll tax, which is levied on the wage bills of larger employers. When the economy is strong, employment rises, and total wages grow, state revenue from payroll tax increases. The second is stamp duty on property transactions, which means state governments benefit directly from rising house prices and active property markets, but also become highly exposed to the property cycle. The third is land tax, mainly from investment properties, commercial land, and high-value landholdings. The fourth includes gambling taxes, insurance duties, and motor vehicle charges. Resource-rich states also receive royalties, especially Western Australia from iron ore, Queensland from coal and gas, and New South Wales from coal.
This explains why state finances are so sensitive to property cycles, wage growth, and resource prices. When house prices rise, stamp duty can increase sharply. When property transactions fall, state budgets quickly feel the pressure. Wage growth and employment growth are good for payroll tax, but if public sector wages rise too quickly, state governments may collect more payroll tax on one side while paying much higher wages for hospitals, schools, police, and transport systems on the other. When resource prices rise, states such as Queensland and Western Australia can enjoy very strong revenues. When resource prices fall, royalties can decline just as quickly. State revenue may look diversified, but many of its components are strongly cyclical.
Local government has the narrowest fiscal structure, and it is also the level of government most closely tied to land. Local councils rely mainly on rates and annual charges, together with user fees, waste and water charges, development application fees, parking fees, venue hire, developer contributions, and grants from higher levels of government. Urban councils tend to have stronger own-source revenue because they have higher property values, greater population density, and more commercial activity. Rural and remote councils face a very different reality. They may cover vast areas, maintain long road networks, and serve small populations, which means their rate base is weak and they depend much more heavily on federal and state grants. Australian local governments do not have income tax, and they do not receive a large direct share of company tax. They cannot expand their finances through an industrial tax base in the way local governments in some other countries can. Their fiscal base is essentially land, housing, service charges, and grants from above.
It is important to distinguish local governments from state governments here. When property prices rise in an area, the most direct beneficiary is usually the state government. More expensive property transactions mean higher stamp duty, and higher land values may also expand the land tax base. For local councils, rising house prices do not mean rates can automatically rise at the same pace. In many states, council rates are capped or regulated. New South Wales, for example, has a rate peg system. Local governments benefit more slowly from property and population growth. They benefit from an increase in rateable properties, developer contributions from new development, a broader base of service charges as population grows, and a larger residential and commercial footprint. In other words, local government gains from real estate and population growth are slow-moving gains, not immediate transaction-tax gains like state stamp duty.
The most important redistribution mechanism in Australian public finance is the GST. The GST is collected by the federal government, but in principle it is distributed to the states and territories. It is not allocated on the basis of “the state that pays more gets more back.” Instead, it is distributed through a formula recommended by the Commonwealth Grants Commission, under the principle of horizontal fiscal equalisation. This process takes into account each state and territory’s fiscal capacity, population structure, service costs, geographic distance, remoteness, Indigenous population share, and health and education needs. Put simply, jurisdictions with stronger fiscal capacity and lower service costs receive a lower GST relativity. Jurisdictions with weaker fiscal capacity and higher service costs receive a higher GST relativity.
This mechanism reveals something essential about the Australian system. In 2026–27, the GST relativities for New South Wales and Western Australia are both below 1, meaning they receive less than a full per-capita share of GST. Victoria is slightly above 1. South Australia, Tasmania, and the Northern Territory are significantly above 1, with the Northern Territory’s relativity at about 5.24. This is not because the Northern Territory has a large economy. It is because it has a small population, vast distances, many remote communities, and extremely high service delivery costs. Its local tax base alone could not sustain basic public services. The Australian system does not try to make every state and territory financially identical. It tries to ensure that different jurisdictions have the capacity to provide broadly comparable public services.
Alongside GST distribution, there are also large specific-purpose payments. In 2026–27, the federal government is expected to pay about A$207.8 billion to the states and territories. About A$109.8 billion of this is GST-related general revenue assistance, while about A$97.5 billion is specific-purpose funding. These specific payments mainly support hospitals, schools, skills training, housing, justice, infrastructure, community services, and environmental projects. For example, National Health Reform funding is around A$37.4 billion. Better and Fairer Schools funding is around A$34.4 billion. The National Skills Agreement is around A$2.6 billion. Social Housing and Homelessness funding is around A$1.9 billion. National Partnership payments are around A$20.2 billion. This money is not simply handed to the states to spend however they like. It often comes with agreements, programs, milestones, and policy objectives.
Local governments also have their own transfer payment mechanism. Financial Assistance Grants are untied federal grants to local governments. In 2025–26, they amount to more than A$3.4 billion. These grants help city councils, but they are much more critical for rural and remote councils. In those areas, the cost of maintaining roads, bridges, drainage, and community facilities is far too high relative to the population and the local rate base. An inland council may have only a few thousand residents but still be responsible for maintaining thousands of kilometres of local roads. That kind of fiscal pressure cannot be solved naturally through local rates. Without federal and state grants, many remote areas would struggle to maintain even basic spatial order.
Australia’s national fiscal balance is therefore not produced by one single policy. It is produced by layers of mechanisms working together. At the individual level, there are the Age Pension, JobSeeker, Family Tax Benefit, the NDIS, Medicare, and remote-area allowances. At the interstate level, there is GST-based horizontal fiscal equalisation. At the state level, there is spending on hospitals, schools, transport, policing, and housing. At the local level, there are Financial Assistance Grants, road funding, regional project grants, and developer contributions. At the infrastructure level, there are programs for roads, communications, water supply, housing, and regional development. The real logic of Australian public finance is not to turn every place into Sydney or Melbourne. It is to prevent places with small populations, weak tax bases, and high service costs from being completely abandoned by market logic.
This system has clear weaknesses. First, the federal government controls the major taxes, while state governments carry many of the fastest-growing service responsibilities. Over time, this creates a mismatch between revenue power and spending responsibility. State governments often say they are short of money, while the federal government uses specific-purpose grants to influence state policy. This creates a form of fiscal control from above. Second, the states’ heavy reliance on stamp duty ties their budgets to the property cycle and adds costs to buying and moving homes. Third, local governments lack flexible tax tools and have to search for room within rates, charges, developer contributions, and grants. Fourth, transfer payments can help remote areas maintain basic services, but they do not automatically create a diverse local economy. Public finance can provide a floor. It cannot substitute for industry.
Seen this way, the strength of Australia’s fiscal system lies in stability and redistribution. It does not rely entirely on each locality’s own fiscal capacity. It recognises differences in geography, population, and service costs, and uses federal taxation and transfer payments to maintain a national baseline of public services. Its weakness is also obvious. State and local governments have limited autonomous revenue sources, many spending responsibilities depend on higher-level grants, and fiscal relationships can easily become political, project-based, and short-term. Australia is not a country of highly autonomous local finance. It is a system in which the federal government concentrates tax collection, state governments carry the main burden of service delivery, local governments maintain the spatial fabric of everyday life, and transfer payments stitch the country back together.
The main data sources are as follows. The 2026–27 federal budget estimates total receipts of A$798.1 billion and tax receipts of A$737.1 billion. The detailed figures for personal income tax, company tax, GST, excise, and customs duties are drawn from Budget Paper No. 1, Statement 5. On the expenditure side, social security and welfare are expected to account for 37.1 percent of federal expenses in 2026–27, health for 16.4 percent, education for 6.9 percent, and defence for 6.2 percent, with total expenses of about A$833.3 billion.
For transfer payments, the federal government is expected to pay about A$207.8 billion to the states and territories in 2026–27. This includes around A$97.5 billion in specific-purpose payments, about A$109.8 billion in GST-related payments, and around A$482 million in other general revenue assistance. Major specific-purpose payments include about A$37.4 billion for National Health Reform funding, A$34.4 billion for Better and Fairer Schools funding, A$2.6 billion for the National Skills Agreement, A$1.9 billion for Social Housing and Homelessness, and A$20.2 billion in National Partnership payments.
The GST system is based on federal collection and distribution to the states and territories according to relativities recommended by the Commonwealth Grants Commission. The 2026–27 GST relativities show New South Wales and Western Australia at 0.81964, Victoria at 1.05742, South Australia at 1.35920, Tasmania at 1.88285, and the Northern Territory at 5.24149.
For state and local taxation, ABS data for 2024–25 shows that state and local taxation revenue grew by 7.5 percent, driven mainly by conveyance stamp duty, payroll tax, and land tax. In 2024–25, payroll taxes were A$41.5 billion, land taxes were A$20 billion, stamp duties on conveyances were A$34.4 billion, and municipal rates were A$25.1 billion. For local government, ALGA records 537 councils across Australia. In 2023–24, local government expenditure was about A$48 billion, with local roads, general public services, and recreation and culture among the major spending areas. Financial Assistance Grants for 2025–26 exceed A$3.4 billion.
