Independent pre-offer risk reports
AddressTwin turns official WA data into a plain-English pre-offer risk report — bushfire, contaminated land, aircraft noise, traffic, crime, schools, transport and local context, every source dated, explained and confidence-rated.
Not all data is available at individual-address level yet. Each result shows whether it is address-specific, suburb-level or proxy-based.

A polished, plain-English due-diligence briefing — not a raw dashboard. Every layer source-dated and confidence-labelled.
Inside every report
What we check
Ten layers, each labelled with how precise the underlying data is — so you never trust a figure more than the source supports.
DFES bushfire-prone mapping — whether the property may sit in a bushfire-prone area (affects BAL construction).
DWER / EPA WA contaminated-sites register near the property.
EPA WA monitoring, including the Kwinana industrial-corridor flag.
Airservices ANEF contours and N70 flight-path events.
Main Roads WA AADT traffic counts on nearby arterials.
WA Police district crime rates and offence mix — context, not property-specific.
Transperth train and bus stops within walking distance.
ACARA profiles and ICSEA. Proximity — does not confirm catchment.
ABS Census — population, age, income and tenure mix.
Landgate sales history and trend — context only, not scored, not advice.
Each layer carries its source, date, granularity and confidence. We never present suburb-level or proxy data as if it were address-specific.
