When travelling, something I often notice is how many cities are governed by a single city council, or at least that the central urban core, comprising a million or more people, is governed by a single council. London has a Greater London Council covering a number of london-wide issues in the greater london area while having many small borough councils.
Sydney appears to have suffered from Sydney-wide issues (e.g. transport) not being properly focussed on – those issues have to be dealt with by the state government as there are many small Councils each covering a small part of sydney.
Has the apparent lack of focus on Sydney-wide issues been a result of the non-existence of an elected single entity covering the wider Sydney area?
