A few other options could be:
Make 2 rows of 5 pills, with each pill on top of the other so you have 2 cylindrical stacks wrap these up together so that you have 1 cylinder that is 5 pills high, and 2 X 2 wide. Following? Wrap these up shit arse tight in something waterproof ie:Glad wrap enough times around. Then wrap a few times around with thick electrician tape. Take the top of a moisturiser bottle (the thicker the moisturiser the better) and plonk them in. Do up the bottle and take or send it through.
Known this to work numerous times. If you want to get really tricky, play around with the weight of the package yopur putting in so it kinda floats. By that I mean so it wont sinkto the bottom to quick or come out to quick if it is tipped opened.
I know of whole pills being sent over, wrapped in a bag and tapped to the inside of a birthday card and making it in one piece. Dont get greedy though. Only send a few at one time, and not too many to the one address. Using different envelopes and writing is also a good idea.
The other option there is, to lay out some glad wrap, put 5 or so pills out on it, cover them over, and crush the pills up. Its not as hard or dumb as it sounds, only thing is you have to make caps, and measuring amounts can be tricky. Then again who is going to complain that there is 50mg too much MDMA in their cap.
You are more likely to get a card or something through than a parcel. Imagine the amount of letters through to Australia fro overseas each day. Surely your chances are good.
If you are sending something, send it to your Aunty addressed to your pet dog. I think there is some law or something that if you are sent something that is not yours, and it is not collected in 1 week, its yours. Thats when you step in and take it. If busted, Aunty knows nothing and it will be hard to prove that she does. And if there is no heat on it, its all yours.
Ive seen that last one done many times, although the police have never got around to Auntys place, so that end part is uncharted waters.
