Whinosp – anything you import into Oz that’s over AU$1,000 value, will be charged 10% GST and an admin fee (and that includes your personal belongings when you emigrate!)
Though bikes are indeed cheaper in the UK, once you add delivery charge (Wiggle & CRC free delivery thresholds don’t apply to bikes) and GST, you’re usually pretty close to being the same price. And it all depends on where the dollar/pound rate is by the time you’re over here and ready to buy. Finally, you have to factor in you’ve you’ve got a ‘grey’ import, so may have problems with warranty and second hand value – the model specs are different in Oz & some common brands in the UK just aren’t well known over here.
Components are different – they are about twice the price in Oz, can be shipping free, and don’t attract GST if you split your orders into less than AU$1000 bundles – and an XT crank is an XT crank no matter which country you bought it from. Thats why so many of us buy components from CRC & Wiggle these days, but very few buy whole bikes.
