Country information
Now, let's get into it with the basics. The Australian address format will teach you how to address a letter for shipping or mailing, and should be written in all capital letters as follows:
- Address line - The recipient's name. If the recipient has a title, such as Sheila of Sunnies, include it here.
- Business or department name - If applicable, add the organization or department name.
- Building number - House or building number are listed here. If there are other address elements, this information should go on a separate line above this one (e.g. locked bag 100).
- Post town (city) and territory/state abbreviation and postal code - This is separated from the locality name by preferably 2 spaces. No punctuation marks are necessary as the extra space notates the separation of address components on this line.
- COUNTRY - AUS, written in all capital letters.
