How we grade a source
The authoritative record itself: the government department or official data file that sets or publishes the fact. Every dollar figure on NestPath traces back to a tier-1 source.
Australian regulators and official consumer-guidance bodies. We use these for definitions, lending standards, and consumer-protection context, not for the underlying numbers.
Reputable private property-data providers. We use these to cross-check our government-derived medians (they agree within about 2%), never as the sole basis for a figure shown to a buyer.
Tier 1 Primary source
The roughly 2.2-million-record file of every property sale registered in NSW. We compute our suburb medians and price-growth figures directly from it via an open pipeline, the first-party basis for the affordability pages and the Deposit Treadmill research.
The official NSW transfer-duty (stamp duty) scale and the First Home Buyers Assistance Scheme (FHBAS) exemption and concession thresholds. Our stamp-duty calculator is built directly from this scale.
Victorian land-transfer duty rates and first-home-buyer duty concessions.
Queensland transfer duty rates, the first-home concession, and the first-home vacant-land concession.
Western Australian transfer duty and the First Home Owner Rate of duty.
South Australian stamp duty rates and the first-home-buyer stamp-duty relief.
ACT conveyance duty and the income-tested Home Buyer Concession Scheme (HBCS).
Tasmanian property transfer duty and first-home-buyer duty concessions.
Northern Territory stamp duty and home-owner assistance.
The Australian Government 5% Deposit Scheme (formerly the Home Guarantee Scheme): the First Home Buyer Guarantee 5% deposit stream, the merged Regional First Home Buyer Guarantee, and the Family Home Guarantee 2% stream for single parents, including property price caps and eligibility.
The First Home Super Saver (FHSS) Scheme: contribution and release caps and eligibility rules.
Lending indicators, dwelling-price indexes and household income context.
Tier 2 Regulator & official guidance
The Government regulator’s consumer-finance guidance: definitions of LMI, offset accounts, comparison rates, and deposit basics that our explainers align to.
The official cash rate and monetary-policy context behind mortgage-rate movements.
Serviceability-buffer and lending-standard rules that shape how much buyers can borrow.
Tier 3 Industry data (cross-check only)
Cross-checking our government-derived suburb medians. CoreLogic’s figures agree with ours within about 2%.
A second independent cross-check on suburb-level price levels and growth.
A third cross-reference for suburb medians where coverage allows.
Why this page exists
Most consumer-finance sites tell you a number without telling you where it came from. We think you should be able to check our working. This is the same idea behind the open government-data pipeline behind our suburb affordability pages and our public first-home-buyer data API: we publish the inputs so you can verify the output.
