For complete bikes, frames and forks, you have to pay a 5% duty. Most parts are exempt (under point 8714 of Schedule 3 of the Customs Tarrif Act 1995), but you still have to pay GST and a $48 Customs handling fee (plus whatever your time is worth). Be warned.
The grouppo looks pretty nice and is light, at around 2107g. Unfortunately, there's a scratch on the rear brake caliper. I'm debating whether to return it: on one hand, who cares; on the other hand, you're paying all this money, so you might as well not get a scratched one, right? Also, what's with all the packaging?
I also lucked into a nice UVEX Anna Meares mouse pad. Cool!
