About_Blipton ( 001 )
Public data, made usable for the people who build housing.
blipton tracks the on/off-market status of every one of NSW’s 4,905,892 residential addresses, every day, and delivers it as a CSV and an API. It exists because the signals were always public — but never accessible to the architects, developers, and designers who need them most.
( 01 ) Why_We_Exist
The property-data market is saturated with enterprise products. The people doing the actual work were priced out.
Australia’s property-data space is commercially crowded: per-seat licences, annual contracts, sales calls, and portals built for institutions. Yet the underlying facts — which addresses exist, and which are publicly advertised for sale — are public data. A small practice testing a feasibility, a developer scanning a corridor, an interior designer timing an outreach campaign: none of them should need an enterprise agreement to know what’s on the market today.
So we built the layer we kept wishing existed: the complete NSW address base, refreshed daily against publicly published market signals, delivered in the formats working teams already use.
( 02 ) Who_We_Are
Built by the people it’s built for.
blipton is built by architects, a development & construction manager, and forward-deployed engineers — a team that has sat on every side of the site-acquisition table, and is passionate about making public web data accessible in a space dominated by closed, expensive incumbents.
People who have sat in feasibility meetings waiting a week for a desktop study on a site that sold on day nine. We build the tool we wished existed at concept stage.
Delivery-side experience across residential projects — acquisition, DA, procurement, build. We know which signals actually move a go/no-go decision, and which are noise.
Engineers who work inside customer workflows, not just on infrastructure. If the data doesn’t land in your spreadsheet, GIS layer, or model, we haven’t finished the job.
( 03 ) What_“Good”_Looks_Like
We hold blipton to the standard NSW has set for live site feasibility.
The NSW Housing Innovation Network’s challenge for live, one-stop site feasibility defines what a good solution looks like. We agree with every word of it — so we measure blipton against each criterion, in public.
( 04 ) Data_In_Decision_Out
Every output is built to end in a decision, not a dashboard.
A complete NSW market-status CSV every day, plus per-suburb extracts — timestamped, versioned, and ready to drop into a due-diligence pack or board paper without manual re-entry.
Every row is keyed to the G-NAF persistent identifier with authoritative geocodes, so outputs join directly into GIS platforms, web mapping systems, and BIM/CAD data environments — no address-string fuzzy matching.
A token-authenticated REST API for per-address status, suburb sweeps, and fuzzy address resolution — built to sit inside existing feasibility models, CRMs, and planning workflows rather than replace them.
( 05 ) What_We_Believe
Only ~1.1% of addresses are on the market, so “99% accurate” is the base rate, not an achievement. We publish recall and precision on the on-market class, and we list what we don’t capture.
We publish an address, a suburb, a postcode, a boolean, and a date. No photos, prices, descriptions, or agent details — our address strings come from the open government register.
Public-web-derived data shouldn’t require an enterprise contract and a sales call. Plans are flat, in AUD, GST-inclusive, and cancellable — and the API starts at 2 cents a call.
The whole platform runs on a deliberately small footprint. Discipline in infrastructure is what makes accessible pricing possible — and keeps us independent in a market of expensive incumbents.
Every address in NSW. On-market or off. Updated daily.
