OK, finally got onto it.
Spoke to the guy I know out here and he said,
He has an agent that he uses weekly out of LA.
At least 4 to 6 bikes would make it feasible as costs with a 20 foot container return shipping, all import/export paperwork etc would be between 7 & 8K AUD (6 bikes is about $1333.00 each)
Sea freight out of LA to Melbourne is about 3 weeks.
Drained of fuel and battery disconnected & taped
Need a metal frame (no timber) to hold the bike so it could be strapped inside a container... he is going to send me a picture of ones made to send some bikes out from Europe
If anyone is interested I can forward the contact details
Hope this helps and abit of food for thought.
Cheers,
