There's a dongle for sale on ebay at the moment, the seller wants £30 for it, what do you mean by upgrade? There was a firmware update that fixed that problem, you can find it either at the fanatec site or www.911wheel.com
The PWTS dongle does indeed work with the original PWT wheel, and with it you don't have to set the date back. I think the only problem will be finding a seller that will ship to australia at a reasonable price.
