How to Find Comparable Sales for Council Rates Objection (NSW)
A step-by-step guide to finding and using comparable sales evidence for your NSW council rates objection.
Lodging a council rates objection without solid comparable sales evidence is like going to court without witnesses. The Valuer General won't simply take your word that your land valuation is too high—they need proof.
The good news? Finding comparable property sales in NSW is easier than most property owners realise. The Valuer General provides free public access to decades of property sales data through multiple online tools.
In this guide, you'll learn:
- Where to find reliable comparable sales data (official NSW government sources)
- How to identify truly comparable properties (not just similar addresses)
- What makes a comparison valid for objection purposes
- How to present sales evidence effectively
Why Comparable Sales Matter for Objections
The Foundation of Property Valuation
NSW land valuations are based on market value—what your land would sell for on the open market as at the valuation date (usually 1 July for council rates).
The Valuer General determines this by analyzing actual property sales. When you object to your valuation, you're essentially arguing that your land value is higher than market evidence supports.
What Makes Sales Data Compelling:

1. Valuer General Property Sales Search
Best for Most ObjectionsWhat it offers:
- • Sales data back to 2001
- • Search by suburb, street, or property number
- • Filter by date range, price range, property type
- • Shows: sale date, price, property description, land size
How to use it:
- Enter your suburb
- Set date range: 6 months before to 6 months after valuation date
- Filter by property type if needed
- Export results and identify comparable properties
Pro tip: Don't just search your street—expand to adjacent streets and similar neighborhoods within your suburb. More data gives you better comparables.
2. Benchmark Component Report
Shows What Valuer ConsideredThe actual sales used to value benchmark properties in your component. Reveals if your property was grouped with truly similar properties.
Example objection argument: "The benchmark component report shows my property was grouped with waterfront properties on [Street Name], however my land is 200m inland with no water views. The sales evidence used is not comparable to my landlocked site."
3. Land Values and Property Sales Map
Visual SearchInteractive map showing property sales with visual comparison of land values across area. Perfect for identifying geographic patterns and spotting valuation inconsistencies.
Best for:
- • Identifying geographic patterns (ridge vs valley properties)
- • Spotting valuation inconsistencies in your area
- • Finding comparable sales on similar topography/location
How to Identify Truly Comparable Sales
Not all properties in your suburb are comparable. The Valuer General looks for "like with like" comparisons.
1. Land Size (±20% is ideal)
If your land is 600sqm, look for sales between 480sqm - 720sqm.
2. Zoning (Must Match)
R2 Low Density Residential ≠ R3 Medium Density Residential
Zoning controls development potential. An R3 block may be worth 50-100% more than R2 even on the same street.
3. Location Features
Must be similar:
- • Topography (flat vs sloping)
- • Views (water, bushland, city)
- • Street type (main road vs quiet)
- • Proximity to amenities
4. Date of Sale (Recency Matters)
Ideal: Within 6 months either side of valuation date
Acceptable: Within 12 months, adjusted for market movement
Problematic: More than 12 months old
How Many Comparables Do You Need?

How to Present Sales Evidence in Your Objection
Format Your Evidence Professionally
Create a simple comparison table:
| Address | Sale Date | Sale Price | Land Size | $/sqm |
|---|---|---|---|---|
| 45 Smith St | 15/03/2025 | $950,000 | 620sqm | $1,532 |
| 12 Jones St | 22/05/2025 | $920,000 | 580sqm | $1,586 |
| 78 Brown St | 10/07/2025 | $985,000 | 650sqm | $1,515 |
| Your property | - | Valuation: $1,200,000 | 600sqm | $2,000 |
Result: Your property valuation is 27% higher than market evidence
Good Example Analysis:
"The five comparable sales identified occurred between March and July 2025, ranging from $1,515/sqm to $1,586/sqm (average $1,548/sqm). All properties are located within 500m of the subject property, have similar land sizes (580-650sqm), flat topography, and R2 zoning. The subject property's valuation of $2,000/sqm represents a 29% premium over market evidence, which is not supported by any superior locational or physical features."
Poor Example:
"My land is overvalued because my neighbor sold for less."
Common Mistakes to Avoid
Using Asking Prices Instead of Sale Prices
Agents often overprice listings. Only actual sale prices count.
Comparing Land+Improvements to Land-Only
Council rates are based on land value only. Don't compare total property values.
Ignoring Zoning Differences
"But it's just across the street!" doesn't matter if zoning is different.
Cherry-Picking Lowest Sales Only
Present a balanced view. Valuers will spot if you only show the lowest sales.
