Stan,
You have to declare the contents in order to clear customs.....things are much stricter than they were in the past.

Brent,
I found an AU exporter not long ago and it is doable with some volume, maybe 4-6 guns or so. Shipping costs were not that bad, he would take care of the paperwork on his end, that just leaves import permits and a customs broker over here. The only way to import guns these days is in groups.
