3. Frequently asked questions about addresses

1. How to find the exact address?

It is recommended to use the "three-address verification method":
① Australia Post address verification tool
② City Hall Property Registration System
③ Cross-check with local yellow pages database

2. Notes on address change

• List of organizations that must be notified:
  • Bank (needs to be updated within 14 days)
  • Immigration Department (affecting visa letter receipt)
  • Tax Office (ATO important documents delivery)
  • DMV (Driver's License Address Change)
• Keep proof of address documents:
  • Utility bill (full address required)
  • Notarized copy of the lease agreement
  • Municipal Rates Notice

3. Relationship between address and identity proof

Under the Identity Verification Act 2015, a valid proof of address must:
✓ Documents issued by government agencies
✓ Validity date within three months
✓ Include complete address information
✓ Type consistent with the application purpose

4. Special address scenario processing

1. New Development Zone Address: You may use a temporary address of "Lot+Planning Number" and need to apply for a formal address from the City Hall
2. Rural address：Use the "distance marking method", such as: 1251 Princes Highway, Berwick VIC 3806
3. Apartment address: The unit number (Unit/Lot) and building characteristics (such as "Block C") must be marked

The Australian Encyclopedia Assistant reminds you: The accurate use of the address system directly affects all aspects of life, such as bank account opening, government services, package receiving, etc. It is recommended to keep 3 copies of address certification documents from different institutions and check the address registration status regularly, especially when moving or renewing documents, be sure to update the address information of all related systems simultaneously.
