National debt reduction, without the debt-free promise.
Unifying government does not cancel what governments owe. This chapter sets out how verified budget improvements could reduce future borrowing — and the arithmetic, gates and limits that keep that claim honest.

The essential distinction
Removing state structures does not erase state debt.
Debt holders must be paid under the applicable terms. Any constitutional transition would require the lawful allocation of assets, obligations, revenues and delivery responsibilities.
The objective is sustainable budget cash improvement that reduces the need for future borrowing — not an accounting trick that moves liabilities from one ledger to another.
Where the national balance sheet starts.
| Measure | 2026–27 | 2029–30 | Definition |
|---|---|---|---|
| National gross debt | A$1,714.1bn | A$2,034.3bn | Borrowings before deducting eligible financial assets; includes national-level consolidation as defined by the source. |
| National net debt | A$1,031.2bn | A$1,279.2bn | Debt less eligible financial assets. It is not interchangeable with gross debt or net financial worth. |
| Annual public debt interest | A$54.2bn | A$77.2bn | An annual financing expense, not an outstanding debt stock. |
| National fiscal balance | −A$67.0bn | −A$50.7bn | An annual budget-flow measure. A fiscal deficit is not the same as the debt balance or operating balance. |

The PBO reports debt-to-GDP trending down in 24 of its 27 long-term scenarios. S38 must be assessed against the existing outlook, not an assumption that the current structure makes all debt unsustainable.
A debt strategy that starts with the books.
1
One debt and balance-sheet register
Reconcile public borrowings, cash, financial assets, guarantees, maturities, pensions and intergovernmental holdings. Publish gross debt, net debt and net financial worth separately; remove internal double counting.
2
Lawful transition and fiscal continuity
Establish an independent constitutional and fiscal transition commission. Preserve bondholder rights, essential services and existing asset and liability obligations. Cost restructuring and IT integration before decisions.
3
Verified operating efficiencies
Audit procurement, shared services, digital platforms, workforce administration and regulatory duplication. Count cash savings only after replacement operations, transition expenditure and necessary service reinvestment.
4
Disciplined capital and asset stewardship
Publish project business cases, whole-life maintenance costs and independent gateway reviews. Count asset proceeds only after disposal costs and future revenue loss, and only if applied to liabilities.
5
Productivity and resilient revenue
Test housing, licensing, energy and workforce-mobility reforms for additional real output and taxable activity. Private bill reductions, GDP growth and government tax receipts are different measures.
6
Intergenerational rules and reporting
Publish rolling 10-, 20- and 30-year debt, debt-to-GDP, interest-to-revenue and fiscal-balance paths with independent review, disclosed revisions and downside cases.
| Lever | Possible effect | Required proof |
|---|---|---|
| Shared services and procurement | Potentially lower public operating expenditure | Audited before-and-after costs and maintained service standards |
| Licensing and digital integration | Less duplicated administration | Government cash impact separated from private compliance benefits |
| Asset rationalisation | One-off reduction in financing needs | Net sale proceeds less disposal costs and foregone revenue |
| Productivity and growth | Possible additional tax receipts | Independently assessed revenue effects net of program costs |
| Fuel and energy security | Potentially lower exposure to import volatility | Separately costed fiscal mechanism; no assumed petrol discount |
| National Service | New fiscal cost and possible social outcomes | Participant, infrastructure, safeguarding and opportunity costs |
Hard arithmetic
Borrowing avoided against an identical baseline.
This is not outstanding debt, principal repaid or a debt-free Australia. It measures how much less the reform scenario would need to borrow than a comparator where these improvements do not occur. A negative value means more borrowing, because transition costs come before improvements. Financing effects are already included — do not add a separate interest saving.

- Your inputs
No complete future debt-stock comparator is supplied, so paths are uncapped arithmetic. They must not be read as avoidance continuing after a comparator would have no debt or financing need. No confidence band is shown.
| Mature net improvement (assumed) | Year 1 | 10 years | 20 years | 30 years | of which financing effect (30 yrs) |
|---|---|---|---|---|---|
| A$10bn / yr | −A$1.50bn | A$51.4bn | A$201.4bn | A$432.1bn | A$185.6bn |
| A$25bn / yr | −A$1.50bn | A$156.1bn | A$545.8bn | A$1,145.4bn | A$506.6bn |
| A$50bn / yr | −A$1.50bn | A$330.5bn | A$1,119.9bn | A$2,334.1bn | A$1,041.6bn |
Financing effect is a component already inside the total, not an addition to it.

What can and cannot feed this model.
Possible subset
$3.13125bn
A hypothetical 50% cash conversion of the $6.2625bn illustrative gross model. It could only be part of a total-improvement scenario — never an extra amount on top of A$10, 25 or 50bn.
Separate new cost
$8.75bn / yr
National Service's illustrative direct annual cost. It would increase borrowing unless separately funded and is not netted here.
Not government revenue
Fuel transfers
Purchaser price sensitivities are changes in consumer spending, not budget savings, and do not reduce public borrowing.
Model limitations
- This is borrowing avoided against an identical counterfactual, not a forecast of outstanding debt, principal repaid or a debt-free Australia.
- A$10bn, A$25bn and A$50bn are assumed mature net operating cash improvements before the explicitly modelled transition cost. No validated S38 net saving establishes any of them.
- The model starts in 2030–31, uses the inherited 10-year ramp, A$1.5bn annual transition costs for 10 years, a constant 4.4% marginal financing rate and nominal amounts without inflation escalation.
- Financing effects are already recursively included. Do not add another interest-saving estimate or present cumulative cash and total debt avoided as separate additive benefits.
- No complete future debt-stock, growth, tax or primary-balance baseline is supplied. The model is uncapped arithmetic and must not imply borrowing can be avoided after a comparator has no debt or financing need.
- A hypothetical 50% cash conversion of A$6.2625bn gross is A$3.13125bn per mature year: a possible subset of a total-improvement scenario, never an additional amount.
- National Service's A$8.75bn direct annual scenario has separate new costs. Fuel purchaser sensitivities are not government revenue or automatic fiscal savings.
Public accountability tests
No claim of debt reduction is published without all seven:
- (a)A named fiscal baseline and year
- (b)The specific debt metric used
- (c)Annual incremental cash effects
- (d)Transition and recurrent costs
- (e)Financing and growth assumptions
- (f)An independent assessment
- (g)A downside sensitivity
Gross debt, net debt, deficits and operating balances are never used interchangeably. Downside cases — recession, disasters, financing shocks and delayed or smaller savings — are reported with every update.
Audit, prove, then scale.
Only verified net improvements, after audit, can be applied to lower new borrowing.
Years 1–2
Independently audit
Publish a consolidated balance sheet, named fiscal baseline and constitutional advice. Assign a validated cost baseline and independent reviewer to each system.
Years 3–5
Pilot and validate
Test administration, procurement and credentials; measure service quality and actual cash impacts. Cost debt-transfer and transition arrangements.
Years 6–10
Scale only proven measures
Expand reforms with positive independently assessed value and acceptable service outcomes. Apply a disclosed share of verified net improvements to lower new borrowing.
Years 11–20
Stabilise and reduce exposure
Review debt maturity and interest exposure, maintain infrastructure, and compare debt-to-GDP and interest-to-revenue with independent forecasts.
Years 21–30
Protect future generations
Maintain renewal reserves and fiscal rules. Update assumptions every budget and stress-test recession, disasters and financing shocks.
What Australians could experience.
Intended, conditional outcomes — not guarantees.
- An accessible annual statement of what all levels of government owe and what assets offset that debt.
- A transparent account of savings achieved, costs incurred and how much borrowing was actually avoided.
- A clearer separation between service improvements, tax impacts, one-off asset proceeds and genuine debt reduction.
- Less exposure to future interest-cost pressures if credible fiscal improvements are sustained.
- Long-term protection of essential services through independent fiscal tests rather than an uncosted promise of a debt-free nation.
