It is quite simple as 500Nitro explained. You do not need an FFL dealer with an importer's license in the US. Any FFL holder can import rifles and shotguns on an occasional basis. To some it mind boggling but the reality is filling out the forms, that can be downloaded, is easy. It does take up to 2 months to receive them back though.

The buyer can even fill out the forms himself as it is a private sale and skip the FFL holder but sometimes the BATF will not allow this and request a Dealer. I have brought in a couple of shotguns and 2 rifles myself but had another couple sent back. It seems to be based on the knowledge of the person in BATF that you are dealing with.

As for the Aussie end, a form filled out from the Department of War/Defense and a shipping Company that will handle firearms. You can do it from your end but I have found that using a dealer familiar with the process works better and for the money involved is a cheap way to go. I don't know anyone in Queensland but do know a couple around Melbourne.

I would think the market for a Searcy in Aus. would be comparable to the US market as well though.
