The short version
AddressTwin is a decision-support tool. It is not financial, legal, building, environmental or property advice. Data may be incomplete, delayed, estimated or inaccurate. Always verify directly with official sources and qualified professionals before making property decisions.

Address Twin is a decision-support information tool. Nothing on this website constitutes financial advice, property investment advice, conveyancing advice, or any other form of professional advice. The scores, ratings, and summaries presented are algorithmic calculations based on publicly available government data and are provided for general informational purposes only.

Bushfire risk information displayed on Address Twin is derived from DFES (Department of Fire and Emergency Services WA) mapping data. This information is indicative only. Official BAL (Bushfire Attack Level) assessments must be conducted by qualified practitioners. Risk zones change over time and the data shown may not reflect the most current classification. Contact DFES or your local council for authoritative bushfire risk information.
Contaminated site information is sourced from the EPA WA Contaminated Sites Register. The register is not exhaustive — sites may be contaminated but not yet investigated, classified, or recorded. The absence of a contaminated site record for a location does not guarantee that the location is free from contamination. Always commission an independent environmental assessment for properties where contamination is a concern.
Scores on Address Twin are calculated using weighted combinations of official data sources. The weighting system is configurable and reflects user preferences, not objective rankings. Two profiles with different weightings will produce different scores for the same suburb. No score on this platform should be interpreted as an objective measure of a suburb's quality or suitability for any particular buyer.
Address Twin takes reasonable care to ensure the accuracy of information displayed. However, to the maximum extent permitted by law, we exclude all liability for any loss or damage arising from reliance on information provided on this platform. Nothing in these disclaimers is intended to exclude rights you may have under the Australian Consumer Law or other applicable legislation that cannot be excluded.
