International shipping is much riskier, so people are usually advised to only order domestically. Certain countries are known for stringently checking international packages -- Australia is at the top of the list, though the US is tough too.
Good packaging consists of multiple layers of vacuum seal and some kind of visual barrier. Fake names, vacant addresses, no return address, trying to mask smells with coffee/foods, etc. are all generally thought to be criteria for 'flagging' a package for more careful review (drug dogs, x-ray machines).
