Hey Tommy
The only differences between the AU and US ones are the headlight (aimed at the other side of the road) and the anti-pollution bits fitted to the california models. Oh and they also have silly reflectors on the sides of their bikes that we don't.
Delivery time from the US depends heavily on who you order from and which carrier you use to get it here. Time of year can also have an influence (eg: xmas period takes longer). Also AU customs pull about 1 parcel in 10 for inspections which can also delay it and possibly have you paying extra for duty. You can expect anywhere from 10 days to 3 weeks for delivery time from the US.
