How Australian Government Data Is Transforming Property Research
Open data from the ABS, ACARA, and state government agencies has fundamentally changed how serious buyers research Australian suburbs. Here's what's available and how to use it.

Australia's Data Advantage
Australia is ranked among the top 5 countries globally for government open data availability by the Open Data Barometer. For property buyers, this is an extraordinary resource that's largely unused. The combination of ABS Census data, school performance data from ACARA, health infrastructure data from AIHW, and transport data from state governments creates a rich evidence base for suburb research that most buyers never access.
The ABS Census: Your Demographic Foundation
The ABS 2021 Census provides suburb-level data on: median household income, housing tenure, family structure, age distribution, and educational attainment. These variables are the best available predictors of a suburb's long-term demographic trajectory — and demographic trajectory is the leading indicator of property market performance over 5–10 year horizons.
Property Price Data: What's Publicly Available
State governments publish property sales data with varying levels of detail. The NSW Valuer General's Office provides detailed property sales data. Victoria's Land Titles Office publishes transaction records. Property research firms like CoreLogic and SQM Research build commercial products on top of this data, adding analytics layers that transform raw transactions into suburb performance metrics.
The Aggregation Challenge
The limitation of open government data is aggregation. It exists across dozens of different government portals, in different formats, updated on different schedules. Most buyers lack the time and technical skills to aggregate and interpret it. This is the problem that suburb intelligence tools like Compare My Suburb solve — aggregating government and open data sources into a single ranked comparison across your suburb shortlist.
