heatmaps.com.au · Last updated: May 2026
A free, interactive property market intelligence platform for Australian buyers, investors, and researchers.
heatmaps.com.au is an interactive map tool that lets you visually explore Australian property market data at suburb, postcode, and statistical area level. Rather than navigating table after table of raw numbers, you can see market conditions across entire cities and regions at a glance — colour-coded by price, growth, yield, rent, and more.
The platform was built to answer the kind of questions that serious property researchers ask: Which suburbs are growing fastest right now? Where are yields strongest relative to price? Where is new supply outpacing demand? It pulls together data from multiple public sources, processes it into a consistent format, and renders it on a live interactive map.
There is no subscription, no paywall, and no login required. The tool is free to use for personal research.
heatmaps.com.au was designed and built by a Sydney-based data engineer. The idea came from frustration with the fragmented state of publicly available property data in Australia — government datasets exist and are genuinely useful, but they are rarely accessible to ordinary buyers and investors in a format that helps them make fast, informed decisions.
The platform combines a custom ETL pipeline (Extract, Transform, Load) that ingests and processes raw government data with a front-end visualisation layer built on modern mapping technology. It is maintained on a personal basis and updated regularly as new official data is released.
The site is independent. It has no affiliation with any real estate agency, property portal, bank, or financial institution. Where affiliate relationships exist with third-party services, they are clearly disclosed in the Terms of Use and Privacy Policy.
All data displayed on heatmaps.com.au is sourced from official government and publicly available datasets. The primary sources include:
Raw government data is ingested through a custom pipeline and processed through the following steps before being displayed on the map:
Data is updated as new official releases become available, typically quarterly for price data and monthly for building approvals. The map displays data as at the most recent available reporting period, shown in the map interface.
Use the menu in the top-left of the map to switch between data layers. Here is a summary of what each layer shows:
| Layer | What It Shows |
|---|---|
| Prices — By Postcode / Suburb / SA1 | Median sale price for houses or units in the most recent annual period. Darker colours indicate higher prices. SA1 (Statistical Area Level 1) is the finest geographic grain available — roughly 200–800 dwellings per area. |
| Growth — Houses / Units | Annual price change (% or $) by postcode or suburb. Green = positive growth; red = decline. Use this layer to identify areas with recent momentum or to compare growth across a city. |
| Rent & Yield | Median weekly rent (houses or units) and estimated gross rental yield by postcode. High-yield areas typically combine lower purchase prices with relatively strong rental demand. |
| New Buildings | Recent building approvals by SA2, split by dwelling type (houses, units, townhouses). High approval counts relative to existing stock can signal future supply pressure. The top-50 oversupply ranking is available under Rankings → Top Oversupply. |
| Owner Occupied | The proportion of dwellings that are owner-occupied (vs rented). High owner-occupier rates often correlate with price stability and community investment in the area. |
| Income | Median household income by suburb from the most recent Census. A useful proxy for purchasing power and rental affordability in an area. |
| Crime (NSW) | Crime rate per 100,000 population by suburb, sourced from the NSW Bureau of Crime Statistics and Research. Currently available for NSW only. |
| Social Housing | The proportion of dwellings classified as social (public) housing by suburb. From ABS Census data. |
| Schools | Government and non-government school locations, plotted as points on the map. Useful for buyers with school catchment requirements. |
| New Land Release | Urban release area polygons showing land earmarked for new residential development. Useful for identifying growth corridors and greenfield markets. |
heatmaps.com.au covers all eight Australian states and territories. Coverage depth varies by state depending on data availability from each state government:
Within each state, coverage extends to all major capital cities and regional centres. Rural and remote areas may have limited data where transaction volumes are too low to produce reliable medians.
The My State menu in the map interface lets you jump directly to your state's main cities.
The map always displays data as at the most recent processed reporting period. Data currency varies by layer:
Subscribers to our data update notifications are emailed when significant new data is published. You can sign up on the contact page.
For data questions, feedback, commercial enquiries, or to report an issue with the map, reach out via the contact page. Response time is typically within two business days.
If you have found a data anomaly or believe a figure is incorrect, please include the suburb or postcode, the layer in question, and the value displayed. We investigate all reported data issues and correct genuine errors in the next update cycle.
