Turn your envelope over. You will write on the side that is an entire blank rectangle, not the side with the flap.

If you are sending a formal letter, add the recipient’s title (“Mr. ,” “Mrs. ,” “Dr. ,” and so on).

If you’re sending your letter overseas, it’ll be more pricey. It’ll cost 2. 10 Australian dollars to have your letter arrive in 10 or more days, and $18. 55 to send your letter in just 5 days. If you have a concession card, you can purchase stamps at a reduced rate. [11] X Research source

If you have a bunch of old domestic 70 cent stamps, you can still use them. You can buy 30 cent stamps online or at a few post offices, to combine with your 70 cent ones to make an even dollar.

Post collection time is 3:00pm local time. That means if you post a letter after 3:00pm, they’ll collect it the next day.
