Independent pre-offer risk reports

Before you make an offer, check the risks the listing won’t show you.

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.

What we check

What the listing won’t usually tell you

Ten layers, each labelled with how precise the underlying data is — so you never trust a figure more than the source supports.

WA hazard layers

Bushfire risk

Address-specific

DFES bushfire-prone mapping — whether the property may sit in a bushfire-prone area (affects BAL construction).

Contaminated sites

Address-specific

DWER / EPA WA contaminated-sites register near the property.

Air quality

Proxy-based

EPA WA monitoring, including the Kwinana industrial-corridor flag.

Aircraft noise

Suburb-level

Airservices ANEF contours and N70 flight-path events.

Traffic noise

Proxy-based

Main Roads WA AADT traffic counts on nearby arterials.

Local context

Crime

District proxy

WA Police district crime rates and offence mix — context, not property-specific.

Transit access

Address-specific

Transperth train and bus stops within walking distance.

Schools

Proxy-based

ACARA profiles and ICSEA. Proximity — does not confirm catchment.

Demographics

Suburb-level

ABS Census — population, age, income and tenure mix.

Price context

Suburb-level

Landgate sales history and trend — context only, not scored, not advice.

Honest about precision

Every result shows how confident the data is

Each layer carries its source, date, granularity and confidence. We never present suburb-level or proxy data as if it were address-specific.

FAQ

Common questions

Is this property advice?+

No. AddressTwin is a decision-support tool that aggregates and explains official and reputable data sources. It is not financial, legal, building or property advice.

Is the data address-specific?+

Some layers may be address-specific, while others are suburb-level, district-level or proxy-based depending on source availability. Every result shows its source, date, granularity and confidence level.

Should I still use a conveyancer or building inspector?+

Yes. AddressTwin helps you ask better questions before offering, but it does not replace licensed professional advice or inspections.

Why use this before making an offer?+

Listings are designed to market the property. AddressTwin is designed to surface independent risk context so you can decide what to verify before committing.
