Queensland Sinking Fund Forecast: Is a 10-Year Forecast Required, and How to Budget It
Queensland law doesn't require a professional sinking fund forecast. It does require the sinking fund budget to reserve for major spending over at least the next 9 years. This guide explains the rule, what the sinking fund can pay for, how to estimate and budget it, and what buyers see.

The short answer
- A professional forecast isn't legally required. The Queensland Government says a body corporate "does not have to get a professional sinking fund forecast". The committee or an owner can estimate the spending.
- A 9-year reserve is required. The sinking fund budget must raise enough for this year's capital spending, plus an appropriate share of major spending expected over at least the next 9 years (s 160(3)).
- The developer provides a 10-year estimate. At the first AGM, the original owner must hand over a detailed estimate of sinking fund spending for the first 10 years (s 96). After that, keeping it current is the body corporate's job.
- The money is separate. It can't be moved between the sinking fund and the administrative fund (s 167(7)).
The rules in one place
| Rule | Section |
|---|---|
| The committee prepares proposed budgets for each AGM | s 160(5) |
| The sinking fund budget raises enough for this year's spending, plus a share of major spending over at least the next 9 years | s 160(3) |
| It considers capital or non-recurrent spending, periodic replacement of major items, and other spending that should come from capital | s 160(3) |
| The AGM adopts the budget by ordinary resolution, and can adjust it by up to 10% | ss 160–161 |
| A budget item isn't, on its own, approval to spend | s 160(7) |
| Contributions are fixed by ordinary resolution. A shortfall needs a special contribution | s 162 |
| Money can't be transferred between the funds | s 167(7) |
| Fund money can be invested as a trustee would, and interest stays in the fund | s 167 |
| The original owner provides a 10-year estimate at the first AGM | s 96 |
What the sinking fund pays for
The sinking fund can pay for (s 169):
- spending of a capital or non-recurrent nature
- periodic replacement of major capital items
- other spending that should reasonably be met from capital
Everything else comes from the administrative fund. The regulation gives repainting common property and replacing air-conditioning plant as sinking fund examples, and insurance as an administrative fund example. "Recurrent" means spending normally made once a year or more often.
How to estimate and budget it
- Start with what you have. Use the original owner's 10-year estimate, the last budget, and any previous forecast or condition report.
- List the major items. Painting, roof, waterproofing, lifts, air-conditioning, pumps, fences, carpets, pool equipment, driveways. Record each item's condition and when it's likely to need work.
- Estimate the cost and year for each item over the next 9 years, and further out for big items such as lifts.
- Spread the cost. For each item, raise an even share each year until it falls due. The regulation's own example is painting due in 3 years: collect a third each year, and adjust as the estimate rises.
- Add this year's spending from the sinking fund.
- Set the contribution. The total is the sinking fund contribution in the proposed budget (s 160(3)).
- Send it with the AGM notice. The AGM adopts it by ordinary resolution and can change it by up to 10% (ss 160–161).
- Update it every year as costs and condition change.
You can ask a professional to prepare the forecast. The Queensland Government says it's a matter for each body corporate.
Checklist
If the fund falls short
If a cost comes up that the budget didn't provide for, or didn't provide enough for, the body corporate must fix a special contribution by ordinary resolution (s 162(2)). Spending over the major spending limit also needs at least 2 quotes (ss 173–174). A fund that keeps falling short usually means the contribution was set too low.
What buyers see
A buyer receives a body corporate certificate before signing (Property Law Act 2023 s 99; BCCM Act s 205). It shows the sinking fund balance, but not a forecast. A buyer who wants to know whether the balance is enough can ask to inspect the budget, the minutes and any forecast (BCCM Act s 205).
Disputes
If an owner thinks a contribution is unreasonable, whether too high or too low, an adjudicator can order it reduced or increased to a reasonable amount (BCCM Act Schedule 5, item 11). Owners can also propose an alternative budget by motion at a general meeting.
Common questions
Do we need a 10-year forecast?
Not by law. You need a budget that reserves for major spending over at least the next 9 years (s 160(3)). A forecast, professional or not, is the usual way to work that out.
How often should we update it?
The law doesn't set a cycle. Because the sinking fund budget is adopted every year, review the estimate before each AGM.
Can we move money from the sinking fund to cover a shortfall in the admin fund?
No. Transfers between the funds aren't allowed (s 167(7)). A shortfall in either fund needs a special contribution.
Where UnitBuddy fits
UnitBuddy keeps the long-term plan beside the sinking fund balance and levies, so the committee can see each year's planned work against what's in the fund when it prepares the budget.
