I have been recently gathering parts from the UK & the US.

So far its just been small low value stuff but i am about to buy some coilovers and possibly some wheels, which, are of a higher value.

What is the situation with import duty? The coils and wheels will be coming from separate sellers at different dates and will both have a value of less than $1000aud.

Am I liable for tax charges once they have landed?

Cheers,
Allan
