This is the best deal I've been able to find on this after looking for quite some time.
Unfortunately I'm after the White / Rose Gold for my wife, so it will be $344.02 but still cheaper than anywhere else by a reasonable margin.
Not sure if Duty needs to be paid on it on entry into Australia but I think even if you add 10% to the price, it's still quite a bit cheaper than I've seen it elsewhere.
The Venu comes down to $392 + shipping as well, which is far from the best it's been but may appeal to some people.
