Fractured Flows: The Case for National Standardisation in Australian Stormwater Management

The management of urban stormwater in Australia is characterised by a profound and systemic lack of standardisation. This is not a superficial issue of minor regional variations, but a deep structural flaw that imposes significant economic, environmental, and social costs upon the nation. The root cause of this incoherence lies not in a failure of individual practitioners or authorities, but in a fundamentally fragmented governance model. Responsibilities are diffused across three tiers of government and a patchwork of water utilities, creating a system that is not merely failing to achieve standardisation, but is structurally incapable of doing so. This fractured jurisdictional landscape inherently fosters inconsistency, stifles innovation, and prevents the realisation of a modern, integrated, and resilient approach to urban water management. Understanding this governance architecture is the essential first step in diagnosing the problem and charting a course for national reform.
