If you are building proptech in Australia --- buyer agent tools, valuation platforms, investment analytics, agency software --- your product needs more than property data. It needs the macro context that determines whether property is affordable, where demand is growing, and how the rate environment affects buying decisions.
ausdata.io provides that macro context as a developer-friendly API, designed to complement (not replace) property-specialised tools like Cotality, Domain API, or HTAG Analytics.
What proptech engineers typically need
Three layers of data:
- Property-specific --- listings, sale history, AVMs, suburb metrics
- Demographics --- population, income, age structure by postcode / SA2
- Macro context --- cash rate, real wages, by-state economic conditions
Most proptech platforms cover layer 1 well, layer 2 partially, and layer 3 barely or not at all. ausdata.io fills layers 2 and 3.
What ausdata.io provides for proptech
Demographics (layer 2)
- ABS Census 2021 G01 (basic demographics) by postcode and SA2
- ABS Census 2021 G02 (selected medians and averages)
- ATO Individual Postcode Median income
- ABS Estimated Resident Population by ASGS
Macro context (layer 3)
- RBA cash rate (F1, daily)
- RBA housing lending rates (F6)
- ABS CPI quarterly + monthly
- ABS Wage Price Index
- ABS Labour Force by state
- ABS Net Overseas Migration
Property-relevant ABS series
- ABS Building Approvals (monthly)
- ABS Building Activity / Completions (quarterly)
- ABS Residential Dwelling Prices (mean and median by state)
- ABS Lending Indicators
Pre-computed composers
/v1/housing-affordability--- mean dwelling value ÷ ATO median income/v1/approvals-vs-completions--- supply pipeline gap/v1/approvals-vs-migration--- supply vs demand ratio/v1/real-mortgage-rate--- variable rate − CPI/v1/macro-snapshot-state--- per-state cash rate, CPI, unemployment, wage growth
Three workflows worth your attention
Workflow 1: Suburb scoring with macro overlay
For each suburb your platform displays, augment with macro context:
curl -H "Authorization: Bearer ak_YOUR_KEY" \
"https://api.ausdata.io/v1/macro-snapshot-state?state=NSW"
Returns NSW-level cash rate, CPI, unemployment, wage growth. Display alongside suburb data so users see the macro environment.
Workflow 2: Affordability calculator
For a buyer-stress test, compute price-to-income with live data:
curl -H "Authorization: Bearer ak_YOUR_KEY" \
https://api.ausdata.io/v1/housing-affordability
Returns the current mean dwelling value ÷ ATO median income ratio. Combine with the cash rate for a "what would it take to afford this" calculator.
Workflow 3: Supply pipeline indicator
For property investment platforms, show users the supply-demand picture:
curl -H "Authorization: Bearer ak_YOUR_KEY" \
"https://api.ausdata.io/v1/approvals-vs-migration?start_period=2015&end_period=2026"
Returns 11-year time series of housing approvals vs net overseas migration. A widening gap signals tight market; narrowing signals oversupply.
Why this matters for proptech
Three reliability issues proptech platforms hit without macro context:
- Affordability claims age fast. A "this is affordable" indicator computed when the cash rate was 0.1% becomes wrong when the cash rate is 4.10%. Live RBA data prevents this.
- State-level demand is uneven. National housing trends do not apply uniformly. Per-state macro data lets you nuance suburb recommendations.
- Supply-pipeline analytics are valuable. Buyers and investors increasingly want to know whether their target market has a building boom or drought. Approvals + completions data is the answer.
Pricing recommendations for proptech

Complementary positioning
ausdata.io is intentionally complementary to property-specialised tools:
- Cotality does property-level AVMs. ausdata.io does the macro context.
- HTAG Analytics does locality-level property data. ausdata.io does cross-source macro and demographics.
- Domain API does property listings. ausdata.io does the surrounding economic data.
Many of our proptech customers use one property-specialised vendor + ausdata.io for the macro / cross-source overlay.
Honest read
If your proptech product covers the macro / demographic side entirely internally, you do not need us. If you have an engineer maintaining scrapers for ABS CPI, RBA cash rate, and ATO income data, we save them a week per quarter.
