Custom charges from Australia to US?

No idea, but why would it be different to buying from any other country? Or maybe you've never bought internationally before?

I have no idea what taxes are like in the US. If it's the other way around, I might be able to help. OK this is a useless post. :yes:
 
I don't think so. After a certain amount, you *might* still have to pay tax. Gift or no gift. I say *might* because sometimes you can be lucky and it goes through custom with no tax.
