Australian Person-Linked Residential Address

Detects a populated Australian residential street address linked to a labelled person. Bare address structure is available for discovery, the balanced tier requires person and residential context plus Australian geography, and the strict tier requires state and postcode corroboration. A parallel household-utility path treats a utility supply/service address linked to a labelled account holder as a person-linked residence. Absorbs the former au-top500-041-home-address and au-top500-054-home-utility-account-addresses classifiers.

Type: regex
Engine: boost_regex
Confidence: medium
Confidence justification: Medium confidence: enforcement requires a populated Australian street structure, a labelled person, an explicit residential relationship, and geographic corroboration. The high tier additionally requires complete state/postcode evidence, while bare structures remain discovery-only.

Known false positives

A person name and valid address can refer to a business contact, venue, or correspondence destination rather than a residence. Mitigation: Require an explicit resident, tenant, occupant, home-address, or place-of-residence relationship for enforcement.
Completed example records in forms, documentation, or training material can look genuine. Mitigation: Apply the shared template-exclusion NOT-group to the 75 and 85 tiers.
Utility-industry documents and commercial accounts mention electricity, gas, water, or meters near business premises. Mitigation: The utility path requires a labelled account holder plus both utility-service and independent account/metering evidence, and company suffixes (Pty Ltd, Ltd, Limited, Inc, Corporation, body corporate) veto it.
