Sydney is already a number of cities, Sydney, Paramatta, Blacktown, Ryde, Liverpool, Canterbury, Blacktown, Penrith, (and a veritable stream of smaller "cities" like Fairfield) and various counties / shires as well, Hornsby, Sutherland, Hills Shire. The issues has never been the names or appellations, the biggest issue since WWII has been the sheer vast size of the suburban sprawl and relatively little coordination and NIMBYism that goes with it.
