Working With Children Check Number (NSW / VIC / WA)

Detects Working With Children Check (WWCC) clearance numbers across Australian states. Covers the NSW structural format (WWC + 7 digits + check letter, e.g. WWC1234567E) and the labelled VIC / WA / generic forms where a WWCC or working-with-children phrase precedes a card or clearance number. The Queensland Blue Card is handled by a separate classifier.

Type: regex
Engine: boost_regex
Confidence: medium
Confidence justification: Medium confidence: the NSW WWC#######E form is highly specific, but the labelled VIC / WA / generic forms match a broad 6-9 digit number near a working-with-children phrase, so corroborating child-screening keywords are required. WA assessment-notice numbering is not publicly standardised and is covered only by the labelled proximity branch.

Known false positives

A working-with-children phrase near an unrelated 6-9 digit number could match without being a clearance number. Mitigation: Require corroborating child-screening keywords within the proximity window.
Sample clearance numbers in HR templates or training material may match the labelled form. Mitigation: The high and medium tiers apply the template-exclusion NOT-group to suppress sample and training content.
