I looked into this a couple of years ago when I was researching buying some photo stuff from overseas. There is a $500 limit if the goods are coming by courier & $1,000 if coming by post, i.e. below these levels it's not worth their while to collect the GST. It is a good system & I think we will see a trend of people placing group orders to get better postage rates. If all you want is some film & paper you might find that $60 USD postage makes it too expensive. However if you get together with some friends & place a bigger order you might find that postage is just $70 or $80 & becomes less significant per item. I find Freestyle is good for this as it is easy to change the shopping basket & check the updated postage. It's especially good now with the Aussie dollar buying nearly 90 US cents.
