Australian Street Locality Reference

Identifies Australian physical addresses using structural street-number + street-name regex combined with road-type, state/territory, and postcode corroborative evidence. Supports standard and extended GNAF road classifications.

Type

Confidence

Known false positives

• Street names in business names or landmarks. Mitigation: Require structural patterns with road-type and geographic corroboration.
• Navigation references mentioning road types without actual addresses. Mitigation: Use proximity-based evidence to ensure numeric components appear alongside keywords.
