Try USPS Priority Mail International for the shipping.

They are the cheapest I've found and I've shipped a couple of front ends from the US to Australia.
To ship a complete front end, (forks, triples, brakes, clip ons, etc) was US$260-. Obviously just the forks will be cheaper. If you can put them in a box and get the dimensions and weight of the packaged item, you can get the shipping quote online here:
