Methodology
PropertyScoutAU scores are research signals designed to help you compare suburbs consistently, understand assumptions and know what to verify next. They are not recommendations.
Score components
Where enough data exists, suburb scores are built from the following components:
| Component | Weight | What it measures |
|---|---|---|
| Yield | 25% | Estimated gross rental yield from available price and rent inputs |
| Growth | 20% | Historical price trend from available sales data |
| Renter demand | 15% | Renter proportion and vacancy indicators from ABS and available data |
| Affordability | 15% | Median price relative to income and comparable suburbs |
| Income stability | 10% | Local income and employment signals from ABS Census data |
| Liquidity | 10% | Transaction volume relative to suburb size |
| Confidence | 5% | Data completeness adjustment — low confidence reduces composite score |
Data sources
Scores are generated from available official, government, ABS and approved public datasets. Source categories include:
- ABS Census — demographics, income, renter proportion, household data
- Government property records — median price and sales transaction data where available
- ABS rental surveys — median weekly rent by suburb and property type
- State valuation authority data — land value and price benchmarks where licensed
PropertyScoutAU does not use live agent listings as a primary data source. Yield and rent figures are derived from official and approved datasets, not scraped listing prices.
Confidence levels
Each suburb page shows a confidence level: High, Medium or Low.
- High confidence — multiple core metrics available including price, rent/yield and demand indicators
- Medium confidence — some key metrics available; one or more supporting indicators missing
- Low confidence — limited suburb-level data available; treat as a starting point only
A low confidence rating is not a negative signal about the suburb. It means the available data is insufficient to rely on the score without additional verification.
Anomaly handling
Yields above 10% and prices that appear inconsistent with available rent data are flagged for review. These may reflect stale inputs, property type mix differences, low transaction sample sizes, or data coverage gaps. Flagged results should be verified against current listings before relying on them.
Limitations
- Scores are research signals, not valuations or advice
- Coverage varies by suburb — small or low-transaction areas may have incomplete data
- Public datasets update on irregular schedules — source dates and confidence notes matter more than a single global "last updated" claim
- Calculated yield uses available median data; actual yields depend on the specific property, condition and current market
