I wouldn't be so sure that they will only go after big time importers, I knew someone in Aus many years back on a private forum who got raided by feds with guns drawn at dawn and they had intercepted something like half a sheet of acid a few grams of k and some mdma (can't remember exact order details). He only ended up getting probation, although he was likely sent to prison shortly after as another vendor sent a package to him after that ordeal and we never heard from him again (plus it was only the first part of a two pack shipment and he never claimed he got the first pack or made any new posts so).
