I never know this either.....
I've heard different stories.....but I was looking at a website today for a crate engine builder in the U.S.A. ( Some REALLY nice looking bits of gear by the way )...but on the section regarding the costs to get them sent to Australia...
http://www.shafiroff.com/shipping.asp
It states in the fine print that we have a "Free trade agreement" between Australia and U.S.A., and that all we need to pay is G.S.T.
Is this right?
If so....there are some nice engines and other gear over there, and the cost to get them shipped over and the G.S.T. still makes them bloody good value.
I know there'll also be other considerations to keep in mind....
Any after sales service/problems for example.
Cheers,
Warren.
