Better take a big boat down there and bring back a big load of wood!...
Actually... I'd use a big boat, but not mine. If and when I do this, I would spend some serious time down there, renting a truck, acquiring wood over several weeks. Then I would fill a small standard container box and have it shipped to the Philadelphia port which I happen to live near, and then have that trucked right to my driveway. Cheapest and slowest... I wouldn't care if it took 2 months to get here. Besides the expense though, which if I did it right I could partially offset by selling some of the wood to local guilds etc, I hear there are other legal hurdles. Because of the possibility of bringing unwanted insect pests into this country, getting a stack of wood that large from a foreign country through customs is no picnic. For starters having no bark on any of the wood is a real big plus, but there are still hoops of fire to jump through. Certifications and inspections both ends to make sure I'm not taking from Australia any species that ain't allowed to leave there (threatened, endangered etc). Lots of paperwork and hassle. I think I'd rather poke a sharp stick in my eye... but think of the once in a lifetime rewards. There are exotic wood importers here that do that on a regular basis, and I probably couldn't do this cheaper than they do, but their list of species is still relatively limited, especially from Australia. Some of the stuff I see in Bob's posts so far simply are not available here at any price, they are just not imported. But... I would then have some for my woodshop. I'm finding out with my little side business here that unique is what sells. People are much quicker to part with their money when they are getting something unique that few others have.
