Finding affordable homes with property data maps
Property decisions are among the biggest most Australians will make, and good decisions start with good data. A property data map puts that data in context, showing where prices sit, how they have moved and how suburbs compare, all in one view.
When CoreLogic (now Cotality) launched Mapping the Market in 2018, built on Esri Australia's GIS technology, it demonstrated what location analytics can do for property decisions. Mapping property data this way continues to give buyers, investors and industry professionals a clear, evidence-based view of the market.
What is Mapping the Market?
Using location analytics, CoreLogic's 'Mapping the Market' app delivered real estate intelligence in a visual form. Users could zero in on any city, click on a suburb and instantly see the current median property price for that postcode.
The interactive map gave buyers a clearer view of Australia's property landscape, helping them find affordable homes within reach of the city. It also gave buyers a clear indication of which suburbs were within their budget by displaying prices relative to the CBD.
CoreLogic's then head of Geospatial Solutions, Matt Lythe, said it would help buyers, sellers and industry leaders to make more informed property purchases at a glance.
"Unlike old reports which relied on graphs to show median property data, this map gives the user an instant snapshot of the nation's property values and shows how prices have trended," Mr Lythe said.

What did Mapping the Market reveal about property prices?
At launch, Mr. Lythe used Brisbane to illustrate the shift.
"If we look at Brisbane, the map shows that in 2012, around 40 percent of suburbs had a median house value of under $400,000, but by the end of 2017, only 22 per cent of suburbs had a median value under 400,000, which shows the big surge in property prices in that five-year period."
The map also showed the contrast in inner-city prices across Australia's three largest capitals, illustrating the gap between Brisbane and Melbourne and Sydney at the time.
"The map uses a simple colour legend to indicate property price. Anything black means the suburb median is above $1.4 million, while the light orange sections show where you can still buy property under $400,000," Mr. Lythe said.
"Sydney and Melbourne's inner-city zones are virtually all black. Yet Brisbane's inner-city appears mostly orange, indicating you can get bargains in suburbs like Keperra, Rocklea and Tingalpa."
What do recent Brisbane property prices show?
More recent data shows how Brisbane’s property market has continued to change. According to Cotality’s November 2026 Home Value Index report, Brisbane’s median dwelling value was $1,018,401 as of October 2026.
Covering houses and units, these figures provide a city-wide view of Brisbane’s market, bringing a more recent perspective to the suburb-level insights illustrated by Mapping the Market in 2018.
How does GIS technology power a property data map?
The Mapping the Market tool was powered by Esri Australia's Geographic Information Systems (GIS) technology, which distils big data into manageable, digestible information for consumers.
Esri Australia's Managing Director, Brett Bundock, said the technology behind the map harnessed millions of pieces of data to produce a visual interface that is user-friendly and informative.
"These maps paint a picture of information, patterns and trends that matter," Mr Bundock said.
"GIS technology allows companies like CoreLogic to quickly and accurately identify critical data, add context and use those results to cast a new light on buyer and seller decisions.
"Advancements such as 3D mapping tools and predictive analytics are allowing more and more commercial property leaders to analyse multiple, large and complex datasets and produce compelling insights that boost business productivity."
