Land Valuation by State: Who Sets Your Land Value, and How to Object

Land valuation by state in Australia

Your land valuation is not set by your council, and it is not what your property would sell for. It is a statutory figure — determined by your state or territory Valuer-General in most jurisdictions, and by the Commissioner for ACT Revenue in the ACT — and it is what your council rates, and in most jurisdictions your land tax, are calculated from. The Northern Territory has no land tax at all.

Which is why the answer to “what is my land valuation” depends entirely on where the land is. Each jurisdiction uses a different basis of value and a different issuing authority, and several do not value the land as if vacant at all: Victoria and South Australia rate mainly on improved value, Western Australia on rental value, Tasmania on an assessed annual value.

The difference that costs people money is the objection deadline. Most jurisdictions allow 60 days. The Northern Territory allows 30, counted from the day the notice was posted.

This article covers, for every state and territory, who issues your valuation, what basis they use and how long you have to object. It then sets out how to run an objection that has a chance of succeeding, and where an independent valuation helps.

What is a land valuation?

A land valuation is the statutory value placed on your land as at a set valuation date by your state or territory Valuer-General, or by the Commissioner for ACT Revenue in the ACT. In most jurisdictions that means its site, land or unimproved value: the value as if vacant. Councils use it to calculate rates, and state revenue offices use it to assess land tax, often for several years until the next revaluation.

That figure feeds directly into both council rates and state land tax, so an inflated figure can cost you money every year until the next revaluation cycle. It is also, deliberately, not the same thing as market value — see capital improved value vs market value for why the two diverge and by how much.

1. What you are really challenging (and what you are not)

When you object, you are challenging the value placed on your land as at a specific valuation date, not the council’s policy choices.

In most states:

• Councils calculate rates using:
  • Site/land/unimproved value (value of the land as if vacant), or
  • Capital Improved Value (CIV) or Gross Rental Value (GRV), depending on state legislation.
• The rating base is set by state Local Government Acts (for example, the Local Government Act 1993 (NSW) and Local Government Act 1989/2020 (VIC)) and tied to statutory valuations under each state’s Valuation of Land or Land Valuation legislation.

When you challenge a statutory land valuation, you are saying:

“The statutory valuation is above (or, in some cases, below) market value at the valuation date, or is based on incorrect property details.”

You are not asking:

• For the rate in the dollar to be changed.
• For council’s budget or rating categories to be altered.

Those are political and policy issues, handled through council consultation and state legislation, not the valuation objection process.

2. Why it matters: multi‑year impact on rates and tax

Statutory land valuations are used for much more than one year’s rates bill:

• Councils use them to calculate general rates and some service charges.
• State revenue offices use them to assess land tax and, in some cases, vacant residential land tax or surcharge regimes.
• In some jurisdictions, the same value can be used for several years until the next revaluation cycle.

Even a modest reduction can compound:

• A $50,000 reduction in taxable land value might trim a few hundred dollars a year from land tax and rates.
• Over a 3–4 year rating cycle, that can run into the thousands for a single property, and much more for portfolios.

Because of this, a well‑prepared objection often has a very strong cost–benefit, especially for higher‑value or multi‑property owners.

3. The legal and tax framework in brief

3.1 State valuers‑general, not the ATO

Valuations for rates and land tax are governed by state legislation, for example:

• NSW – Valuation of Land Act 1916 (NSW) (land value as if vacant).
• QLD – Land Valuation Act 2010 (Qld) (site value/unimproved value).
• VIC – Valuation of Land Act 1960 (Vic) and Local Government Act 1989/2020 (Vic) (CIV and site value).
• SA, TAS, WA, ACT, NT – equivalent Valuation of Land and Local Government Acts.

The Australian Taxation Office (ATO) does not set or review council land values. Land tax is explicitly a state or territory tax, and the ATO directs taxpayers to state revenue offices on assessment and dispute processes.[General ATO land tax guidance]

However, a corrected statutory valuation can influence:

• State land tax assessments going forward.
• In some cases, how land value is apportioned in CGT or depreciation calculations if you or your adviser choose to rely on that value. ATO practice statements on market value (for example, for CGT market value substitution) emphasise the use of qualified valuers, which is consistent with using a RICS‑regulated valuer for objection evidence.

3.2 Mass valuation and why errors happen

State valuation offices typically use mass valuation methods, valuing thousands of properties in “components” based on comparable sales and statistical models.

That system is efficient, but it can:

• Over‑generalise across a neighbourhood.
• Miss site‑specific constraints (flooding, access, contamination, easements).
• Carry forward data errors (wrong land size, zoning, use).

The objection process exists precisely because the system accepts that individual valuations may be wrong in specific cases.

4. Objection windows: how long do you have?

Most jurisdictions allow 60 days from the issue date on your valuation or rates notice. The Northern Territory allows 30.

• Northern Territory – 30 days from the date the notice was posted. The clock starts before the notice reaches your letterbox, and this is the shortest window in the country.
• Queensland – 60 days from the date of the valuation notice.
• NSW, South Australia, Western Australia, Tasmania and the ACT – 60 days from the notice.
• Victoria – 2 months from receiving the assessment notice for land tax valuations.

Always check the deadline printed on your own notice: it governs your rights, whatever a table says.

Key points:

• Missing the deadline can mean your objection is rejected as out of time.
• Some states allow late objections in limited circumstances, often requiring a statutory declaration explaining why you could not act earlier (serious illness, not receiving the notice, etc.).
• Appeal rights (to tribunals such as NCAT, VCAT, QCAT, SACAT, etc.) have separate, shorter time limits, often 21–60 days from the decision letter.

If you are considering a formal valuation, you should still lodge a basic objection before the deadline and note that a professional report will follow. You can then supply the report once available.

5. State‑by‑state overview

Every jurisdiction has its own forms and portals, but the pattern is similar.

Land valuation in Queensland

• Valuation basis: Site value (non‑rural) or unimproved value (rural).
• Authority: Queensland Valuer‑General (Department of Resources).
• Objection period: 60 days from the date of the valuation notice.
• Process:
  • Review valuation and published valuation and sales data for your area.
  • Contact the department if you want clarity on how the figure was reached.
  • Lodge an objection online or via Form 58S/58U, setting out acceptable grounds and attaching evidence.
  • Late objections must explain the delay and may require a statutory declaration.

Peak body AgForce has highlighted large valuation increases in rural and regional QLD for 2024–26 and has publicly urged landholders to object by the relevant closing dates.

Statutory valuations in Victoria

• Valuation basis:
  • Capital Improved Value (CIV) widely used for council rating.
  • Site value used for land tax.
• Authorities: Valuer‑General Victoria; objections lodged via the State Revenue Office (SRO) for land tax or via councils for rates, all feeding back to the same statutory valuation.
• Objection period: 2 months from receipt of your land tax assessment (taxable value).
• Process (SRO):
  • You may object to the taxable value, not to the tax rate.
  • Objections can be lodged online using your assessment details.
  • You must provide reasons and as much information as possible.
  • Valuer‑General Victoria typically has four months to issue a written decision.

For council rate notices, many Victorian councils refer you to the Valuer‑General and provide objection instructions on their websites.

Land valuation in South Australia (Adelaide)

• Valuation basis: most SA councils rate on capital value, with site and annual value also permitted; site value is what land tax is assessed on. All are determined under the Valuation of Land Act 1971 (SA).
• Authority: Office of the Valuer‑General (OVG SA).
• Process: The OVG describes a four‑step approach—Receipt of Notice, Understand your Property Valuation, Lodge an Objection, Review of your Objection.
• If you are dissatisfied with the OVG’s decision, you can apply to SACAT, which can confirm, decrease or increase the valuation. Objections to SACAT must generally be made within 21 days of the decision.

Statutory valuations in Western Australia (Perth)

• Valuation basis:
  • Gross Rental Value (GRV) for most urban properties.
  • Unimproved Value (UV) for many rural holdings.
• Authority: Valuer‑General WA, via Landgate.
• Objections: Owners may object to GRV or UV within a statutory period after the valuation is issued, commonly around 60 days. Grounds include incorrect property description, GRV too high relative to rents, or inappropriate comparisons.

Land valuation in NSW (Sydney)

• Valuation basis: Land value (unimproved value as if vacant) as at 1 July in the valuation year.
• Authority: NSW Valuer General (Property NSW).
• Use: Provides values to councils for rates and to Revenue NSW for land tax.
• Objections: Owners can usually object within 60 days of a Notice of Valuation or the first rates/land tax notice that uses a new value. The process involves an internal review and, if needed, appeal to NCAT or the courts.

Land valuation in the Northern Territory (Darwin)

The NT is the jurisdiction where getting this wrong costs you fastest, because the objection window is the shortest in the country.

• Valuation basis: Unimproved capital value (UCV) — the value of the land as if vacant.
• Authority: the Northern Territory Valuer-General, an independent statutory officer under the Valuation of Land Act 1963 (NT), who prepares and maintains the valuation roll.
• Revaluation cycle: the Act requires a UCV valuation of rateable land in the Territory at least every three years.
• Objection period: 30 days from the date of posting shown on your notice — half the window most states allow. If the Valuer-General disallows your objection, the NT Government’s guidance states you then have a further 30 days from that decision to apply to the Northern Territory Civil and Administrative Tribunal (NTCAT), which under s 20A of the Act may review a decision to disallow an objection or allow it only in part. Confirm the date on your decision letter — the tribunal’s own time limits govern.
• What it feeds: council rates. The Northern Territory does not levy land tax — it is the only Australian jurisdiction that does not — so an NT land valuation affects your rates bill and not a land tax assessment.
• Darwin specifically: City of Darwin’s 2025/26 Declaration of Rates and Charges adopted the unimproved capital value from the valuation roll prepared under the Valuation of Land Act 1963 as the basis of assessed value for allotments in the municipality.

One NT quirk worth knowing before you object: City of Darwin strikes rates as a fixed charge plus a percentage of UCV, and some rating categories carry a minimum amount. Where part of your bill is a fixed charge, a lower UCV only moves the variable part; and if your property already sits at the minimum, it may not move the bill at all. Check which basis applies to your rating category before spending money on evidence.

Statutory valuations in Tasmania

• Valuation basis: the Valuer-General provides land value, capital value and Assessed Annual Value (AAV).
• Objection period: typically around 60 days from the notice.

Land valuation in the ACT

• Valuation basis: Average Unimproved Value (AUV) — the average of your land’s UV over the last five years (a three-year average until 1 July 2020).
• Process: objections are lodged with the ACT Revenue Office within the stated time, with appeals to ACAT. See our ACT unimproved value and rates objection guide for the detail.

Always read the objection deadline printed on your specific notice; that governs your rights.

6. Grounds to challenge a statutory land valuation

Valuation authorities emphasise that you must show the valuation is wrong, not simply that rates are unaffordable. Common valid grounds:

• Value exceeds market value at the valuation date
  • Recent sales of comparable properties indicate a lower market level.
• Incorrect property details
  • Land area, zoning, permitted use, heritage status, or improvements are wrong.
• Key physical constraints not considered
  • Flooding, erosion, bushfire risk, contamination, geotechnical instability.
  • Restricted access, easements, covenants or rights of way reducing development potential.
• Inconsistent treatment compared with similar properties
  • Nearly identical neighbouring sites are valued materially lower without clear justification.

Authorities and tribunals consistently stress that evidence is decisive. Assertions that a valuation is “unfair” carry little weight without data.

7. Step‑by‑step: how to run an effective objection

Step 1 – Read your notice carefully

Note:

• The valuation date (often 1 July of the previous financial year).
• The type of value (land value, site value, CIV, GRV, etc.).
• The deadline for objection and where to lodge it (Valuer‑General, council, or revenue office).

If you own multiple properties, track all of their deadlines in one place.

Step 2 – Gather market and property evidence

Focus your evidence on what a willing buyer would have paid for your land as at the valuation date, assuming a normal sale.

Useful evidence includes:

• Comparable sales
  • Sales of similar properties (size, zoning, location, potential) close to the valuation date.
  • Where possible, extract a per square metre rate and compare to your assessed value.
• Rental evidence (for GRV objections)
  • Actual achieved rents for your property or comparable properties.
• Planning and constraint documents
  • Zoning maps, overlays, flood plans, contamination reports, vegetation or heritage controls.
• Physical evidence
  • Photos showing access issues, topographical challenges, or other site limitations.

For many owners this is where an independent valuation adds immediate value: a RICS valuer will collect, filter and analyse this evidence in a format that aligns with how valuers‑general themselves work.

Step 3 – Ask for the authority’s sales or rationale (if available)

Some jurisdictions allow you to:

• Request the sales evidence or valuation “component” data used for your property, or
• Discuss the valuation informally with a council or Valuer‑General officer before finalising an objection.

Comparing their sales list with your property often reveals:

• Sales that are not truly comparable (better zoning, larger regular sites, superior aspect).
• Missing constraints or site‑specific issues.

You can then address those points directly in your objection.

Step 4 – Lodge a concise, on‑time objection

Use the official form or portal for your state (for example, QLD Forms 58S/58U, VIC SRO online objections).

A strong initial objection will:

• Clearly identify the value you consider correct (or at least a justified range).
• State specific grounds, for example:
  • “The land value exceeds market value as at 1 July 2025. Comparable sales A, B and C support a value in the range $X–$Y.”
• Attach an initial bundle of evidence or state that a professional valuation report will follow.

Keep it factual, structured and unemotional. You can expand with more detail later if requested.

Step 5 – Respond to follow‑up and participate in reviews

Valuation authorities may:

• Request additional information.
• Arrange an inspection.
• Offer an informal conference to discuss your evidence.

Respond promptly and stay focused on the valuation date and market evidence. If the decision remains unsatisfactory, consider escalation:

• Tribunals/courts – bodies like VCAT, NCAT, QCAT, SACAT review the valuation afresh and can increase, decrease or confirm the figure.
• Strict appeal windows apply; check your decision letter immediately.

8. How an independent RICS valuation helps your objection

An independent valuation is not mandatory, but for many owners it can be the difference between a speculative objection and a defensible professional case.

Landmark Valuations is a RICS‑regulated firm, complying with the RICS Red Book Global 2025 and International Valuation Standards. A report prepared on that basis typically supports an objection in several ways:

• Market‑based value opinion
  • A clear, evidence‑backed value as at the relevant date, using accepted methods (direct comparison, income capitalisation for GRV cases, etc.).
• Robust comparable sales analysis
  • Systematic selection and adjustment of comparable sales, with commentary on why each is or is not truly comparable.
• Identification of overlooked constraints
  • Explicit analysis of flood risk, contamination, easements, zoning or planning controls that may not have been fully reflected in the mass valuation.
• Tribunal‑ready format
  • If your matter proceeds to NCAT, VCAT, QCAT, SACAT or similar, a report prepared in line with professional standards is far easier for the decision‑maker to rely upon.

For more complex scenarios (for example, historical disputes, related‑party transfers, or restructures), a retrospective valuation or related‑party transfer valuation may be required to align different regulatory and tax requirements:

• Retrospective valuation – for past dates, often relevant where earlier assessments are questioned or where ATO market value rules need to be documented.
• Related party transfer valuation – when properties are transferred within a family group or structure and stamp duty, land tax and ATO market value rules intersect.

Where you do not yet know whether a formal valuation is justified, you can obtain an initial fee indication via Landmark’s quote page.

9. Common misconceptions and “gotchas”

A few traps that regularly catch owners:

• “My rates went up, so the valuation must be wrong.”
  • Rates can rise because of council budget decisions even if your valuation is unchanged. Objections can only address the valuation, not rating policy.
• “I can object at any time this year.”
  • You usually have 60 days from the notice date — 30 in the Northern Territory, 2 months in Victoria for land tax. After that, your options narrow considerably.
• “If I object, they might increase my value.”
  • Legally, the value can go up or down, but if you are relying on solid evidence and a realistic value, upward adjustments are rare in practice.
• “I’ll stop paying until it’s sorted.”
  • In most states you are expected to pay on time even while an objection is pending. If successful, you receive an adjustment or refund; interest and penalty rules vary by statute, so check your notice and state revenue office guidance.
• “I don’t need evidence; I’ll just explain it’s unfair.”
  • Valuers‑general and tribunals consistently emphasise that only evidence‑based arguments carry weight.

---

10. Strategic tips for property owners

To maximise your chances when you challenge a statutory land valuation:

• Start immediately – diarise deadlines as soon as the notice arrives.
• Anchor everything to the valuation date – evidence must reflect market conditions at that date, not today.
• Structure your case – summarise your argument, then provide a table of comparable sales or rentals, followed by constraint evidence.
• Be realistic – pitching at a defensible figure is more credible than arguing for an implausibly low value.
• Get professional help where the stakes are high – for significant landholdings, complex zoning or large portfolio land tax exposure, a professional valuation will usually pay for itself several times over in avoided over‑assessment.

Frequently asked questions

How long do I have to object to a land valuation?

It depends on the jurisdiction. NSW, Queensland, South Australia, Western Australia, Tasmania and the ACT allow 60 days from the notice, and Victoria allows two months from receiving a land tax assessment. The Northern Territory allows 30 days, counted from the date the notice was posted rather than the date you received it — the shortest window in the country. If the NT Valuer-General then disallows your objection, the NT Government’s guidance states you have a further 30 days from that decision to apply to NTCAT for review. Missing a deadline can see an objection rejected as out of time regardless of its merits, although some jurisdictions accept late objections in limited circumstances, usually with a statutory declaration explaining the delay. Read the date printed on your own notice and diarise it the day it arrives.

If I object, can my land valuation be increased?

Legally, the value can go up or down. In practice, if you are relying on solid evidence and arguing for a realistic, defensible figure, upward adjustments are rare. Tribunals such as NCAT, VCAT, QCAT and SACAT review the valuation afresh and can confirm, decrease or increase it, so pitching at a credible value matters more than an implausibly low one.

Do I still have to pay rates while my objection is pending?

Yes. In most states you are expected to pay on time even while an objection is being decided. If your objection succeeds, you receive an adjustment or refund. Interest and penalty rules vary by statute, so check your notice and your state revenue office’s guidance rather than withholding payment while you wait.

What are valid grounds to challenge a land valuation?

You must show the valuation is wrong, not simply that the rates are unaffordable. Common valid grounds are that the value exceeds market value at the valuation date, that property details such as land area or zoning are incorrect, that physical constraints like flooding or contamination were not considered, or that near-identical neighbouring sites are valued materially lower without justification.

Does an independent valuation help my objection?

It is not mandatory, but for many owners it is the difference between a speculative objection and a defensible professional case. A RICS-regulated valuation provides a market-based value opinion, robust comparable sales analysis, identification of overlooked constraints, and a tribunal-ready format that a decision-maker at NCAT, VCAT, QCAT or SACAT can rely on. Authorities consistently stress that evidence is decisive.

Conclusion and next steps

Challenging a statutory land valuation in Australia is a technical, time‑sensitive process, but it is also a clear legal right. If you act within the objection window, focus on market evidence and document any property‑specific constraints, you can often correct overstated land values and reduce your rates and land tax for years to come.

If you have received an unfavourable notice and want an independent, RICS‑standard opinion to support your objection, you can request a tailored proposal from Landmark Valuations via the online quote form.
