Even more interesting is how all of Geelong is excluded from Melbourne’s count when Gosford’s included in Sydney’s count, despite neither place being continuously connected to the larger city, Geelong being closer to Melbourne than Gosford is to Sydney, and Geelong having just as large a proportion of daily commuters as Gosford.

The reality is that Melbourne’s population outpaced Sydney a long time ago and the boundaries are only just starting to catch up.
