What fiscal policy is

Fiscal policy is the government's use of expenditure and revenue, through the Commonwealth Budget, to influence the level of economic activity, the allocation of resources and the distribution of income. The Budget lands in May each year, with a mid-year update in December.

Federal Government budgets and budget outcomes

The outcome

Budget outcome = receipts − outlays

A surplus means receipts exceed outlays, which is a net withdrawal from the economy. A deficit means outlays exceed receipts, which is a net injection. Balanced means neither.

Quote the underlying cash balance rather than the headline figure. It excludes volatile one-off items such as Future Fund earnings, and it is the number the Budget papers lead with. Express it as a percentage of GDP so it is comparable over time.

The 2026-27 Budget, delivered on 12 May 2026 by Treasurer Jim Chalmers, forecasts an underlying cash deficit of $31.5 billion, roughly 1% of GDP, with deficits holding near that level for three years before improving. Gross debt sits at $1,051.0 billion, or 34.0% of GDP, and net debt at $616.9 billion, or 19.9%.

Revenue comes principally from individual income tax, by far the largest source, then company tax, the GST and excise duties. Expenditure goes principally to social security and welfare, again the largest, then health, education, defence and general public services including interest on debt.

Cyclical against structural

This distinction separates a strong answer from a weak one, so make it early.

The cyclical component is the part of the outcome caused by the business cycle working through automatic stabilisers. In a downturn tax revenue falls and welfare spending rises on their own, worsening the outcome without anyone deciding anything. The structural component is what would remain if the economy were running at full capacity, and it reflects deliberate policy decisions.

Why it matters: a purely cyclical deficit corrects itself as the economy recovers, while a structural deficit does not and requires a policy change to fix. Judging fiscal policy by the headline outcome alone confuses the two.

The stance of fiscal policy

Stance is judged by the change in the outcome, never its level. The balance moving towards deficit, or towards a larger deficit, is expansionary. Moving towards surplus, or towards a smaller deficit, is contractionary. No significant movement is neutral.

The consequence catches students constantly: a budget in deficit is not automatically expansionary. If this year's deficit is smaller than last year's, the stance is contractionary even though the Budget remains in deficit.

Effects of budgetary changes

The syllabus names three effects, and they need handling separately.

On economic activity

Fiscal policy shifts aggregate demand directly through government spending, and indirectly through consumption via taxation and transfers:

G ↑ or T ↓ → AD ↑ → output ↑ → derived demand for labour ↑ → employment ↑ → incomes ↑ → further consumption through the multiplier

The multiplier amplifies the initial change, but leakages to savings, taxation and imports mean the real multiplier sits well below what the simple formula suggests, and further below again for an economy as import-dependent as Australia.

Automatic stabilisers operate here too. Progressive income tax and unemployment benefits cushion the cycle without any decision being taken, and unlike discretionary measures they act with no lag whatsoever.

On resource use

Fiscal policy decides how resources are allocated between the public and private sectors, and within the public sector.

Government provides goods and services the market under-supplies, particularly public goods subject to the free rider problem and goods carrying positive externalities such as education and health. Taxes and subsidies correct externalities by making private costs reflect social costs. Infrastructure investment raises productive capacity, which is a supply-side effect rather than a demand-side one and is worth flagging as such. Industry assistance channels resources into particular sectors.

The trade-off is that shifting resources into the public sector may improve allocation where markets fail, but it may equally displace more productive private activity.

On income distribution

This is where fiscal policy is the primary instrument, and monetary policy cannot help at all.

Progressive income tax takes a higher proportion from higher incomes. Transfer payments, including the Age Pension, JobSeeker and Family Tax Benefit, are means-tested and therefore well targeted. The social wage of Medicare, public education and public housing raises real living standards without ever appearing as income.

The combined effect is substantial: the Gini coefficient for final income is markedly lower than for private income. Making that before-and-after comparison explicitly is one of the strongest evidential moves available in Topic 4.

There is a tension worth naming. Highly progressive taxation combined with generous means-tested transfers can create poverty traps, where withdrawn benefits stack on top of income tax to produce punishing effective marginal tax rates, weakening the incentive to work more.

Methods of financing deficits

Three methods, with quite different consequences.

Borrowing from the domestic private sector

The government issues Commonwealth Government Securities to Australian investors, and the consequence is crowding out.

Government borrowing adds to demand for loanable funds, which raises the real interest rate, moves the economy up its investment demand curve and reduces private investment. Part of the intended expansionary effect is cancelled out.

The evaluation is conditional and that is what makes it worth marks. Crowding out is strongest when the economy is near capacity and weakest when there is substantial spare capacity. In 2020, with idle resources everywhere, the argument carried very little force. In 2026, with unemployment at 4.4% and below the NAIRU, it carries considerably more.

Borrowing from overseas

Selling securities to foreign investors avoids crowding out domestic investment and brings in foreign capital.

The cost is that it adds to net foreign debt, already $1,452.6 billion at March 2026, and the interest paid overseas is a debit on net primary income, which worsens the current account. Where the debt is denominated in foreign currency it also creates exchange rate exposure, though Australian government debt is issued in Australian dollars.

Borrowing from the Reserve Bank

Monetary financing, where the RBA creates money to buy government debt, is what people mean by printing money.

It is not used, for two reasons. It is highly inflationary, since it expands the money supply with no corresponding increase in output. And it compromises central bank independence, and with it the credibility that anchored inflation expectations depend on.

Distinguish it from quantitative easing, because the two get conflated. QE is the central bank buying government bonds on the secondary market to lower long-term interest rates. It is not financing the government directly at issue.

The use of a surplus

Four options, and the choice between them is itself examinable.

Repaying debt reduces the interest burden on future budgets and rebuilds the capacity to respond to the next downturn. Depositing into a fund is what the Future Fund was established to do, meeting the Commonwealth's unfunded superannuation liabilities; sovereign wealth funds serve the intergenerational purpose of converting a temporary revenue windfall into a permanent asset. A government can also reduce taxation or increase spending in a future year. Or it can simply hold the surplus, withdrawing demand, which is appropriate where the objective is to restrain an overheating economy.

The intergenerational argument is the one worth being able to make. Revenue from extracting non-renewable resources is temporary by definition. Consuming it leaves nothing behind, while investing it in a fund or in productive capital preserves the value for the generations who will not have the resource. Norway's sovereign wealth fund is the standard comparison, and the standard criticism of how Australia handled the mining boom.

Advantages and limitations

Fiscal policy can be targeted at specific sectors, regions or income groups, where monetary policy is blunt. It directly addresses income distribution, which monetary policy cannot touch. Its automatic stabilisers act immediately with no lag. It remains effective at the zero lower bound, when interest rates cannot fall any further. And it can raise productive capacity through infrastructure and human capital investment rather than only managing demand.

Against that, the implementation lag is long, tied to the annual Budget cycle, and major spending takes time to legislate and deliver. Political constraints bite hard, since tax rises and spending cuts are unpopular, which produces a structural bias towards deficits. Crowding out is a real cost near capacity. Debt accumulation raises future interest costs and constrains future budgets. And spending programmes are difficult to reverse, because they create constituencies that resist their removal.

What the exam does with this

Fiscal policy carried Section III in 2021 and in 2019, where the question was about sustained budget deficits, and it appears in combination with monetary policy in 2023 Q28.

Five things to get right.

Judge the stance by the change rather than the level. That single distinction separates candidates more reliably than anything else in the topic.

Separate cyclical from structural components of the outcome.

Use current Budget figures with the date attached: a $31.5 billion underlying cash deficit, about 1% of GDP, in the 2026-27 Budget.

Draw the crowding out diagram if financing comes up, and condition your judgement on where the economy sits relative to capacity.

Cover all three effects when the question asks about budgetary changes. Most candidates write about activity and forget resource use and distribution entirely.
