Australia Address Generator
Generate Australian format samples from 12 maintained locality/postcode pairs across six states plus ACT and NT. Compare four-digit strings, state/suburb mapping and CSV/JSON round trips, including Darwin 0800. This is not complete town, rural-route or external-territory coverage.
An Australian fixture for suburb, state and postcode fields
Follow the suburb, NSW state code and four-digit postcode through your form’s field mapping. Additional fixtures cover the six states plus ACT and NT; choose Darwin 0800 to test leading-zero retention separately.

Keep suburb, state abbreviation and postcode in separate import columns. A combined display line is not a replacement for the stored fields.
What to check
- Reopen the record and confirm NSW remains the state code instead of moving into the suburb field.
- Use additional fixtures for units or territories: the generator has no independent unit field or complete rural-route coverage.

A preservation test should detect this change. Test intentional normalization against a separate contract.
What this version does not cover

Australia: Address structure and practical checks
Postal-code handling
Australian postcodes are four digits. Store them as text; Darwin 0800 exercises a leading zero.
Address fields
A typical test line keeps suburb or city, state abbreviation and postcode together. Do not infer a postcode solely from the state.
Scope of these samples
These are synthetic format examples, not verified delivery addresses or real identities. A listed region does not mean that every city, street or building there is covered.

FAQ
Are all Australian states available?
The selector now includes the six states plus ACT and NT, with limited locality examples. External territories and complete rural-route coverage are not provided.
Is City the same as a broad metropolitan area?
Use the locality/suburb label actually exported by the fixture. Do not automatically replace it with a broader metro label during import.
Does this sample include a unit number?
There is no independent unit field. Create a separate unit-address scenario if your checkout needs to preserve one.
