If you don't do it already, start a fun Christmas tradition this year, write a letter to Santa! Well, not you personally, I suggest it's more appropriate for your kids, maybe you could help.
Santa is very very busy and gets a lot of mail, so he has to spread the load amongst many locations, he may even engage in a little outsourcing to his elves.
Australia Post has a special agreement with Santa, they know his exact address, simply:
1. Address your envelope to:
NORTH POLE, 9999
2. Place a 60c stamp on your envelope
3. Include your return address on the back of the envelope.
Santa will reply to all Children in Australia!
