Hence why JJP have a distributor in Melbourne. It would be a pain in the arse for JJP to ship individual machines around the world, I'm sure they would much rather send containers.
I understand that every export needs to be shipped with its manifest and freight, terminal fees, duties and GST can be worked out. However, if some smuck decides to investigate 'whats in the box' they are going to charge you to pull it aside, open and inspect. You can't predict this. If some uneducated customs guy decides the machine needs to be fumigated (even though paperwork is in order) you will be hit up for AQIS fees. If you forwarder isn't AQIS approved, the machine will have to be transported to an AQIS approved site, fumigated and then cleared. This sort of stuff does happen with individual personal imports, which, in essence is what is going to happen if you deal direct with Jack.
