Australia Address Format Guide
Australian postal addresses normally place the recipient first, the street or delivery service on the next line, and the suburb, state or territory abbreviation, and four-digit postcode together on the final domestic line. International forms should add AUSTRALIA as a separate final line.
Standard Australian address layout
Sophie Wilson
Unit 8 45 Collins Street
MELBOURNE VIC 3000
AUSTRALIA
Australia Post recommends three to four address lines. The locality, state abbreviation, and postcode belong on the same line, with clear spaces between each component. Punctuation is generally unnecessary in a postal presentation.
Field mapping
| Form field | Australian value | QA consideration |
|---|---|---|
| Address Line 1 | Unit 8 45 Collins Street | Allow unit, level, street number, name, and type. |
| City / locality | Melbourne | “Suburb or town” is a clearer local label. |
| State / territory | VIC | Accept the eight standard abbreviations. |
| Postcode | 3000 | Store as text so leading zeroes remain intact. |
| Country | Australia | Use the full country name for international display. |

Form testing checklist
- Preserve four-digit postcodes such as 0800 instead of converting them to numbers.
- Test unit, level, PO Box, and Locked Bag lines without forcing every address into a street-only format.
- Verify NSW, VIC, QLD, WA, SA, TAS, ACT, and NT.
- Allow long suburb and Traditional Place names without truncation.
- Keep locality, state, and postcode together in labels, receipts, and exports.
Reproducible postcode and locality test
| Input | Expected storage | Failure signal |
|---|---|---|
| 0800 | Four-character postcode string | The database stores 800. |
| DARWIN NT 0800 | Locality, territory, and postcode remain distinct. | The territory is mistaken for part of the town name. |
| Unit 8 45 Collins Street | Unit and street survive label and CSV output. | The unit is discarded because Address Line 2 is empty. |
| Locked Bag 10 | Alternative delivery service is accepted. | Street-number validation blocks submission. |
Run the postcode case through entry, JSON serialization, database persistence, CSV export, and import. The exact value must remain 0800. A four-digit shape check does not establish that a postcode matches a locality or that an address is deliverable.
