Watch the leading zero

Some Australia postal codes begin with a zero, such as 0800. Spreadsheets and some web forms silently drop it, turning 0800 into 800 — which is either a different place or not a valid code at all. Format the column as text before pasting codes into a spreadsheet.

How an address is written in Australia

This is the order Australia's postal service expects. Square brackets mark what you replace.

[Recipient name]
[Street address]
[Suburb] [State] [Postal code (2060)]
AUSTRALIA

A postal code is required in a complete Australia address. The state is also required.

Look up a specific address

For the code covering one particular street or building, Australia's postal service publishes an official finder: www1.auspost.com.au/postcodes. It is authoritative and kept current, which third-party copies often are not.
