Hi I ship to Oz once or twice a month and have no problems at all.
You MUST put on a CN22 sticker and fill it out properly or your package WILL get opened and checked. They are really extremely hot on anything larger than a postcard entering the country so without a customs label telling them what is inside I can almost guarantee it wont get through, or if it does get through, it will arrive at your customers house wrapped in yellow customs tape declaring it has been checked!
Customs Labels (CN22 stickers) – dont panic, I always write “Mens Socks” or “Mens Underpants” or the like on it, dont put anything too far fetched because it is weighed so try and think of something that is in similar size and weight to what you are sending! If you simply write apparel on it, they will want to know WHAT apparel – so you have to be explicit, even if the truth is bent slightly 🙂
You must put a return address on the envelope too, but you can either put your Post Office address or a “dummy” one for your own safety.
Since I have been filling out the little CN22 stickers for the customs every single package of mine has reached its destination in 7-10 days no problems; I never used to need the special stickers a few years ago but as I said before they have really cracked down on security.
