In AU if customs seize a smallish order then generally nothing happens, no love letter and no knock at the door. However you can be sure that seizure gets logged on a system somewhere and if a pattern of seizures is detected or larger amounts get picked up then I'm sure bad things might happen. I've been quite sure up until recently that the AU customs things gets hyped up way too much however I'm now starting to hear from quite a few people who are not receiving their stuff, either way the debate will rumble on and speculations made. All I will say is if you get a no show consider that address burned.
