Australia Complete Address Format Guide
Australian postcodes contain four digits. The leading digits broadly correspond to state or territory routing, but special-purpose codes also exist. Domestic landlines use a leading 0 plus a one-digit area code; international format removes the zero after +61. Mobile numbers begin 04 domestically or +61 4 internationally. Given-name-first order is common, but multicultural naming patterns are widespread. Forms should accept more than two words and avoid requiring a middle name.

Implementation and validation notes
Australian postcodes contain four digits. The leading digits broadly correspond to state or territory routing, but special-purpose codes also exist. Domestic landlines use a leading 0 plus a one-digit area code; international format removes the zero after +61. Mobile numbers begin 04 domestically or +61 4 internationally. Given-name-first order is common, but multicultural naming patterns are widespread. Forms should accept more than two words and avoid requiring a middle name.
Validate required state, character set, length, and syntax on the client, then repeat validation on the server. Preserve the original input and normalize into a separate field; never truncate local scripts, compound names, or leading zeroes to fit a single Western assumption.
This guide describes common formats rather than an official registry and cannot enumerate every exception. Generated output is for testing only, not delivery, calling, identity verification, or real account activity.

How should Australia address test data be stored?
Store the original value as a string so leading zeroes, spaces, hyphens, accents, and local scripts are preserved. Use a separate normalized field for search.
Does correct formatting prove the data is real?
No. Syntax validation cannot prove an address is deliverable, a number is assigned, or a name belongs to a real person.
