I have ordered a seige cdr class jetfire, ldr class dotm ss44 prime and ss38 and it is expected to come in august this year.

And although the aud is at 0.60-0.70 at the moment (the total was 426.64 aud at 1aud- 0.6828 USD).
As it could get worse, i am wondering (if i have to) how you would fill out a fill customs import form if it goes over a $1000?
