What is the cost of mailing a postcard from Italy to Australia?

As of May 2021, the most recent postal rates published by Poste Italiane, the post office of Italy, indicate that the cost of mailing a standard postcard from Italy to Australia is €1.35. This includes airmail service with priority treatment.

Note: Please consider that postal rates may change over time.

I recommend checking the website of Poste Italiane or using a postage rate calculator for the most up-to-date and accurate information.
