Data & methodology.

Prices & growth

Heatmaps visualises median house and unit prices across postcode, suburb and statistical area layers. Growth is calculated as year-on-year change in both dollars and percent, where sufficient observations are available.

Small transaction counts can distort suburb-level growth, so charts and rankings use sales counts as a confidence signal and avoid implying precision where the sample is thin.

Rents & yields

Rent layers show the latest available median or average rent data by property type and geography. Gross yield is calculated as annualised rent divided by the property value.

Yield is useful, but it is not a complete investment measure. It should be considered alongside growth, liquidity, supply risk, income, schools, crime and other suburb context.

Development approvals & oversupply

Development approval layers use recently approved dwellings from local councils and national building approvals data. Higher approval counts or value can indicate incoming supply and should be interpreted as a supply-risk signal, not a standalone forecast.

Oversupply rankings use Statistical Area 2 geography where that is the most stable level for development approval data.

Demographics

Income, owner-occupier balance and social housing layers use Census 2021 data. These signals add long-term suburb context to the faster-moving property and rental data.

Median weekly household income is used as one proxy for household capacity and local affluence. Owner-occupier share is used as a neighbourhood composition indicator, with 66% treated as a broad Australian midpoint in the overall scoring model.

Schools & crime

The schools layer uses ICSEA 2024 and NAPLAN-related school data where available. The crime layer uses multi-state crime rates per 100,000 population for NSW, VIC, QLD, SA, WA and ACT where available.

Crime and school indicators are contextual signals. Missing optional signals are treated carefully in rankings rather than automatically excluding a suburb.
