For Australia, last I checked, the best prices were from Starbike
http://www.starbike.com/en/brands/rohloff/
and Bike24
http://www.bike24.de/1.php?content=2...lang=2&mid=118
in Germany.
Unfortunately with the Aussie dollar dropping in value, you'll maybe get stuck paying duty and gst (tax) as you'll likely be over the Au $1000.00 cut off point for duty/tax free.
I was lucky and got in just before it dropped and my external mec, QR disk braked 36H Rolloff came in at $999.00 escaping the govt's cut.
Buying from the EU means theres no European VAT (tax) to pay (delivery to non EU states).

Suggest you ask on the forum at bicycles.net.au to get a local heads up on best prices and where etc.
Price and availability change regularly.
From time to time business's lose the ability to ship different brand names overseas.
eg. Wiggle no longer ship Ortlieb to Australia nor Amazon Nikon cameras - swings and round about.

I bought fitting spares from sjscycles.com
http://www.sjscycles.co.uk/find.asp?...page=1&geoc=AU
in the UK and grabbed a torque arm from ebay so I'm good to go if I ever get sick of my current bike and wish to retro fit my hub to a different frame, such as yours.
