Welcome to the site :cool:
Thanks for setting up your User CP and updated information relating to your location. Grab a spot on the couch and tell us a bit about yourself. How long you have been riding, what kind of riding you prefer, where you are located, etc. We will do our best to hook you up with some fellow dirt bike enthusiasts. We have a good size group in Australia.
As far as 144 kits, I would suggest you contact Eric. He is the king of 144 kits and has been doing them for a couple of decades (if I remember correctly). Click on his name or on the logo in the left vertical bar. He and Rich are very familiar with how to ship overseas. They do it all the time.
Again, welcome to the site and shout if you have any questions!
