This Vision and Transition Strategy defines a vision of a water sensitive future for Greater Sydney, NSW, and outlines the broad steps the city should take to enable a transition towards this future. It is the outcome of a project by the Cooperative Research Centre for Water Sensitive Cities, which brought together 51 leading thinkers across water, planning, environment and development in Greater Sydney in a series of action research workshops. Participants considered the city’s long-term water aspirations, benchmarked today’s water sensitive performance and explored strategic priorities for the short- to medium-term that will be important in pursuing their water sensitive city vision.
