It might be worth contacting Austrian customs to explain what these packages are - and to ask if there is a method for receiving returned non-commercial goods without having to pay tax. That's what Alan did with UK Customs and he got a helpful reply.

I can't do anything about the postage, but I can mark the value as zero - although that may look suspicious. And let me know how to write 'returned goods' in German!
