I agree with @craig.thomler that regular presentations and workshops are the way to go.
Sometimes innovation spawns innovation in unforeseen ways, this is my example:
Innovation 1: Brisbane City Council Published City Plan 2014 as an on-line resource and a smart way of delivering the reference documents and maps explaining the Councils planning objectives.
Innovation 2: BCC expanded the number of projects that can be done without planning permission to promote economic development but one must have an expert-level understanding of CityPlan to know what projects can be done on a site.
Innovation 3: Brisbane Marketing appoint the Chief Digital Officer and reach out to business promoting Digital, putting me in contact with Open Data advocates in Council.
Innovation 4: Fountainhead Group invents www.RightToGo.com to bring simplicity to (necessary) town planning complexity and to connect Homeowners with design-led Businesses to kick-start projects.
Foster innovation within Goverment.
Be in a hurry to support private and community sector innovation.
