Shipping bikes or even parts from the U.S. to Oz can get complicated and expensive. I feel bad when the shipping costs are almost as much as the item itself and try to find ways to lower those costs as much as possible when I have sold items to members here, but you get what you pay for with the shipping. Both parties need to be protected, so I will not ship without documentation, tracking and insurance.
As someone suggested when purchasing a motor vehicle from another country, you really need to do your homework. I have sold and shipped two bikes to OZ and both transactions went well. They required many emails back and forth, lots of paperwork and photos taken all along the process.
East Coast Vintage may or may not give what everyone would think is a good description, but I will give them credit for taking and posting lots of large, high definition photos of the bikes. Look at all the photos carefully and ask lots of questions before purchasing from anyone.
