Bit of a new topic but seems the best place to ask it ...

I'm a recent road biking convert, and got into it since being away from Oz. I'm returning home next year after what will be 6 years away and I haven't decided which of Melbourne, Sydney or BrisVegas I will move to, it will mostly be pending employment but was just wondering if anyone had any opinions as to which city is the best to live/ride in for a roadie?

Any ideas?
