Hi Eric,
Where in the USA are you moving from? I would suggest contacting someone like Atlas Vanlines, I am in the International Relocation Industry, and have seen many partly restored cars being brought in to both NZ and Aussie. I do know that the big expense your end will be the loading of the container, so if you can somehow arrange for it to be done, or do it your self, you will save yourself alot of money. Where in Australia are you moving to?, I maybe able to give you an email address, and they would be more than happy to answer any further questions you may have. Feel free to email me if you require any more help. brett_thomson@mim.net.au
