feat(postcodes/AU): bulk-import 3,175 codes via Australia Post (#1039)#1434
Merged
Conversation
Adds the importer + first run for Australia. Australia Post publishes
postcode data under CC-BY 4.0; this PR uses the community-maintained
matthewproctor/australianpostcodes mirror as the source-of-truth feed
(redistributable under the same CC-BY licence).
1. bin/scripts/sync/import_australia_post_postcodes.py — pipeline that
groups CSV rows by postcode and picks one canonical record per code
(first locality alphabetically). State resolution is direct iso2
match: CSV uses ACT/NSW/NT/QLD/SA/TAS/VIC/WA, identical to states.json.
2. contributions/postcodes/AU.json — 3,175 records covering all 8
Australian states/territories with 100% state_id and 100% coordinate
resolution.
Validation (zero errors)
- All codes match countries.postal_code_regex (^\\d{4}\$)
- All FKs resolve, all state_codes agree with state.iso2
- No auto-managed fields present
