Home utility account addresses

Detects populated Australian residential utility service addresses. Enforcing tiers require utility service context, account or metering context, and Australian geography; the strict tier also requires a labelled account holder.

Type: regex
Engine: boost_regex
Confidence: medium
Confidence justification: Medium confidence: a populated Australian street structure corroborated by both utility-service and account/metering evidence is materially stronger than utility labels alone. The high tier additionally proves account-holder attribution and complete state/postcode geography.
Detection quality: Topic false positive

Should match

7B George Street — Exact 65 probe - populated street structure without utility context
Electricity account number 884201; service address: 18 Banksia Road, Brisbane QLD 4000 — Exact 75 probe - populated utility address with account and geography but no account holder
Account holder: Full Name; electricity account number 884201; service address: 18 Banksia Road, Brisbane QLD 4000 — Exact 75 probe - blank-form account-holder placeholder must not elevate the address to 85
Account holder: Noah Williams; NMI 41020012345; electricity supply address: 12 Ocean Rise, Redcliffe QLD 4020 — Exact 85 probe - populated utility address with holder, account evidence, state, and postcode
Water account number 771028; service premises: 91 King Street, Melbourne VIC 3000 — Populated water-service account address

Should not match

Supply address: — Blank label must not be treated as a populated address
The electricity account team updated the billing policy. — Utility account prose without an address value
The electricity market seminar is at 200 George Street, Sydney NSW 2000. — Utility topic near a venue but without account or metering context must not enforce
Documentation example: Account holder: Noah Williams; NMI 41020012345; supply address: 12 Ocean Rise, Redcliffe QLD 4020 — Complete but explicitly documented example is excluded from enforcing tiers
Meter number 123456 was retired after the network upgrade. — Meter context without a populated service address

Known false positives

Utility-industry documents can mention electricity, gas, water, or meters near business premises. Mitigation: Require both utility-service and account/metering context for enforcing tiers, with account-holder attribution at high confidence.
Completed sample bills and account forms can contain realistic service addresses. Mitigation: Apply the shared template-exclusion NOT-group to the 75 and 85 tiers.
