A Valid Australian Address Example
A valid Australian address example has exactly two lines: a street line (street number and street name) and a last line carrying the suburb, the state or territory abbreviation, and the four-digit postcode, all on one line — for example "4 Example Street" on the first line and "SURRY HILLS NSW 2010" on the last. A four-digit Australian postcode carries no internal structure comparable to a French département code; it is simply a four-digit range assigned per state, which UPU S42 records as the simplest of the numeric postal-code schemes this comparison covers.
Australia is the one country in this dataset where Fake Addresses reaches full coherence rather than resolving an area by point-in-polygon: the underlying source already ties every address to its own real geocode, a real street, and a real suburb by relational identifiers the source itself publishes, so there is no separate area to interpolate a point within. The street number on a generated record is still chosen outside every real number recorded for that exact street, which is what keeps the record non-deliverable even though the street and suburb around it are both genuinely real.
That full-coherence level is the honest ceiling for the jurisdictions actually ingested, not a blanket claim for the whole country. Fake Addresses names on its generator page exactly which Australian jurisdictions are covered today, so a QA engineer testing an Australian shipping or billing form knows whether a given state or territory is represented in the current dataset before relying on it.
Australian Postcode Format and Examples
Fake Addresses generates an Australian postcode that is always exactly four digits, assigned in broad ranges per state and territory, with no letters and no hyphen:
| Postcode | State/territory | Suburb | Full last line |
|---|---|---|---|
| 2000 | NSW | Sydney | SYDNEY NSW 2000 |
| 3000 | VIC | Melbourne | MELBOURNE VIC 3000 |
| 4000 | QLD | Brisbane | BRISBANE QLD 4000 |
| 6000 | WA | Perth | PERTH WA 6000 |
How Australian Address Format Compares to the United States and the UK
Fake Addresses formats Australia as keeping the whole last line, suburb through postcode, on one row like the United States, but uses a plain four-digit postcode with none of a ZIP+4's extended-digit structure:
| Country | Last-line order | Postal-code position |
|---|---|---|
| Australia | Suburb, state/territory abbreviation, postcode | End of the last line |
| United States | City, State, ZIP+4 | End of the last line, per USPS Publication 28 |
| United Kingdom | Post town, then postcode on its own line beneath it | Final line, on its own |
Synthetic Test Data Generation for Australian Test Addresses
Synthetic test data generation for Australia gets a genuine advantage most countries Fake Addresses covers do not have: because full coherence is reached for every ingested jurisdiction, a QA engineer can treat the suburb, state and postcode on a generated Australian record as fully real rather than as an area-level approximation. The only field deliberately kept non-real is the street number itself, chosen specifically to fall outside every number the source actually recorded for that street.
Fake Addresses states its Australian coverage plainly on the random Australia address generator, naming exactly which jurisdictions are ingested today rather than implying nationwide coverage the underlying source does not yet have. A QA engineer testing an Australian delivery or billing form should check that page for the current jurisdiction list before assuming a specific state or territory is represented. The two ingested jurisdictions each carry their own page with real suburb, street and postcode figures: the Australian Capital Territory generator and the Other Territories generator.
Every generated Australian record still stays non-deliverable by construction despite the higher coherence level. The street number is chosen specifically to avoid every real number recorded on that street, so a test fixture built from this data carries no risk of resolving to somebody's real address even where the street and suburb around it are both genuinely real, and a QA engineer can rely on that guarantee holding regardless of which ingested jurisdiction a given record happens to come from.
Frequently asked questions
Why does Fake Addresses reach full coherence for Australia?
The underlying Australian source ties every address to its own real geocode, street and suburb by relational identifiers the source itself publishes, so there is no separate area for Fake Addresses to interpolate a point within, unlike a country where only a postal code resolves to an administrative area.
Is an Australian postcode always four digits?
Yes, with no letters and no hyphen, assigned in broad ranges per state and territory. Fake Addresses generates every Australian postcode against that same fixed four-digit pattern, distinct from a US five-digit ZIP code or a UK postcode's mixed letters and digits.
Does full coherence mean a Fake Addresses Australian address is deliverable?
No. Even with a real street and suburb, the street number on a generated Australian record is deliberately chosen outside every real number recorded for that street, which keeps the record non-deliverable by construction regardless of how real the surrounding fields are.
