Core PII detection patterns for Australian Privacy Act 1988 compliance. Covers government identifiers, healthcare numbers, business identifiers, and personal contact information.
Detects Australian Business Numbers (ABNs), which are unique 11-digit identifiers issued by the Australian Business Register to entities carrying on a business in Australia. ABNs are commonly formatted as groups of 2-3-3-3 digits separated by spaces or hyphens. The ABN includes a check digit mechanism, but this pattern relies on format matching combined with corroborative evidence rather than algorithmic validation.
Detects candidate Centrelink Customer Reference Numbers consisting of 9 digits followed by a letter. The bare shape is not unique and requires a CRN/Centrelink label for enforcement.
Detects Australian Company Number patterns. This pattern is based on a Microsoft Purview built-in sensitive information type. Users already running Purview may prefer to enable the built-in SIT directly, or use this version as a starting point for customisation.
Identifies Australian Medicare card numbers (10-11 digits, first digit 2-6). Filters same-digit sequences. Requires corroborative health-scheme keywords for reliable detection.
Discovery-only compatibility coverage for Australian driver's licence number candidates across all states and territories. The stable au-motor-vehicle-permit slug is retained for catalogue, collection, workbook, and package compatibility. State and territory enforcement belongs to the eight au-*-driver-licence-number SITs. Microsoft Purview tenants can instead select the free built-in Australia Driver's License Number entity (1cbbc8f5-9216-4392-9eb5-5ac2298d1356); this compatibility pattern is not a custom clone of that built-in.
Detects NDIS Participant Number patterns. A 9-digit number starting with the prefix 43.
Identifies Australian Tax File Numbers (TFNs) — unique nine-digit identifiers issued by the Australian Taxation Office. Uses an inline mod-11 Checksum validator with AllDigitsSameFilter and TextMatchFilter to exclude known test values.
Identifies candidate Australian passport numbers using a broad one- or two-letter prefix followed by seven digits. The regex does not validate an issued passport series; Australian travel-document and issuing-nation evidence are required for enforcement.
Identifies electronic mail addresses in local-part@domain.tld form using a pragmatic RFC 5322 / WHATWG HTML Living Standard subset: bounded local-part (64 characters, per RFC 5321) and domain-label quantifiers, not the full RFC 5322 address-list grammar (no quoted-string local parts, comments, or domain literals). Unlike the WHATWG "valid e-mail address" definition, a dotted domain ending in an alphabetic (or xn-- punycode) top-level label is required, so dotless intranet values such as user@localhost are deliberately excluded. Retina image asset names (logo@2x.png) are rejected in the primary. Absorbs the former global-email-address classifier.
