Nationality and National Origin (Australia)

Detects references to nationality/citizenship/immigration-status disclosure in Australian documents: nationality fields, national origin, citizenship status, visa status, and naturalization records. Not framed as an Art-9-style special category (Australia has no equivalent regime) — sensitivity here rests on immigration-status/visa risk under the Migration Act 1958 (Cth) and on the "national origin" limb of the Racial Discrimination Act 1975 (Cth), distinct from that Act's race/ethnicity limb covered by the sibling au-racial-ethnic-origin pattern. Topic-grade detector, low confidence by design.

Confidence justification

Low by design. Nationality/immigration status has no fixed format, so it is detected purely by topic vocabulary. The bare word "national" appears constantly in unrelated contexts (National Bank, nationally recognized, national holiday); the regex is scoped to full disclosure phrases only, and hits should be paired with corroborative keywords (citizenship, visa, immigration) to raise precision.

Should match

• The onboarding form records nationality and citizenship status. — Citizenship status phrase present
• File notes his current visa status and immigration category. — Visa status phrase present
• HR record documents naturalization status for payroll tax purposes. — Naturalization status phrase present

Should not match

• National Bank of Australia reported quarterly earnings. — Near-miss proper noun ("National Bank"), no nationality disclosure
• She received a nationally recognized award for her research. — Near-miss adverb ("nationally"), not "nationality"
• The office is closed for the national holiday on Monday. — Unrelated "national" (holiday), no disclosure vocabulary

Known false positives

• The word "national"/"nationally" appears in unrelated contexts (proper nouns like National Bank, adverbial "nationally recognized", "national holiday") that have nothing to do with a person's nationality or citizenship. Mitigation: The regex targets full disclosure phrases ("national origin", "citizenship status", "visa status") rather than the bare word "national"; require corroborative keywords (citizenship, visa, immigration, passport) for confidence.
