>>2795471 (OP)what meds exactly anon. dunno about straya specifically but been to a few places with pharma products now
most of the time absolutely nothing happens and no one cares, occasionally you might have to produce a prescription but here they stick those onto the packaging anyway so you don't even need to think about it
if you are on something on controlled lists then you might have to get some kind of customs pre clearance to bring it in. plenty of people don't bother and they almost always get away with it, but if you have a problem with this then it'll be an enormous problem for want of five minutes of paperwork the week before
if your drugs need to be kept cold, needs needles (insulin etc) then the little refrigerated packs you get look super sus on x ray. I've seen people get ak47s pointed at them for this. if you have that kind of thing then tell the security guys about it before they scan it
there are still a few countries that treat certain diseases as witchcraft and will be hostile if you try to bring in associated medicines. western countries won't give you any grief about your psychosis pills or whatever but this can be a problem elsewhere
