Australia Address Format Guide
Australia uses a 4-digit postcode, with different states occupying different numeric ranges — New South Wales (home to Sydney) mostly starts with 1 or 2, Victoria (home to Melbourne) starts with 3, and Queensland starts with 4. The "Suburb" field in an Australian address is essential — it doesn't mean a residential outskirt in the usual sense, but rather the specific named neighborhood within a city, roughly equivalent to a "district" field elsewhere, and it's included in nearly every address, even for a city's downtown core. The standard format is: house number + street, Suburb + state abbreviation + postcode, Australia, for example "1 Martin Place, Sydney NSW 2000, Australia".
Addresses generated by this tool for Australia are rule-based test data, not backed by a real geographic database. They are intended only for form validation, checkout flow testing, database population, UI prototyping, and localization testing — not for use as a real delivery address or identity proof.
