Frequently Asked Questions
How do I find a postcode for a specific suburb?
You can use the official lookup tool by clicking the button above. Simply type in the name of the suburb, town, or city, and select the correct state (e.g., NSW, VIC, QLD) from the suggestions to reveal the correct postcode.
What is the difference between a street address and a PO Box postcode?
In many Australian towns and cities, physical street addresses share a standard 4-digit postcode. However, Post Office (PO) Boxes or Large Volume Receivers (LVRs) might have a unique, dedicated postcode.
Always ensure you are using the correct one depending on how the mail or parcel is being delivered (to a street address vs. a postal box).
Why isn't my new estate address showing up?
New Subdivisions and Developments
Newly developed estates and subdivisions take time to be officially registered with local councils and added to the national delivery database. If your address is very new, it might not appear in search results immediately.
You may need to wait a few weeks for the database to update, or contact your local delivery center to confirm your mailing details in the interim.
