I am totally in the dark about present overseas export restrictions, but here at the receiving end, things like this can be achieved, at least in theory. Start by discussing the proposed import with customs & take their advice. Then contact your local state or territory 'weapons licencing branch'.
I have recently been investigating import of a deac Bren Gun from U.K and both Aust Customs and Queensland Police happily sent me the applicable paperwork. Neither agency hesitated in providing assistance. I have spoken to several others who have 'had a friend' who tried to import a weapon etc into Australia and they always say the same thing......"it can't be done". From what I have experienced, the regulations change unexpectedly, current regulations are often interpreted differently from person to person (except once the deal is done & item has arrived) and beurocracy reigns supreme.
Some of the regulations are just unbelievable. For example, I have been told (more than once) that without a collectors licence, I would need to do a safety course and join a club to be able to get a permit to own a Bren Gun that has been deactivated.
Never did get the Bren, UK regulations were difficult/impossible to overcome. Not sure which of these it was. I lost interest before I slipped into madness.
There are a number of dedicated import agents which can potentially decrease the load and stress of dealing with Govt departments. Costs may outweigh the loss of hair on your part.
Good luck!
