Local government advocacy in the 'suburban age': an institutionalist interpretation of Melbourne's evolving sub-metropolitan regional structures.

The 'suburban age' has been conceptualised as the dominant global urban spatial reality for the 21^st Century, yet the politics associated with this heightened expansiveness remain underdeveloped. Of relevance is the potential for suburban discontentment across a myriad of spaces centred upon the under provision of infrastructure and employment. With urban regions often highly fragmented by local government boundaries, bottom-up inter-local government responses assume significance, including sub-regional advocacy given enduring hierarchical government dependencies. In consideration of the evolving strength of sub-regional advocacy, three institutionalist themes are introduced: credibility, coherency and coordination. Empirical insights are presented from chief executive officer (CEO)-based interviews conducted across expansive Melbourne, Australia. In Melbourne, a 'weak mayor/strong CEO' local government system predominates beneath a state government with extensive metropolitan responsibilities. Melbourne's sub-metropolitan regional structures have recently looked to strengthen their external presence through actions illustrative of the identified themes, with local government CEOs playing a key role in directing their evolving character. The global 'suburban age' must be associated with heightened sub-regional competition across enlarged urban regions, the management of which will present a growing spatial challenge for political leaders.
