Campbelltown City Council SA Verge Garden Policy
From their Vibrant Verges Booklet (pdf) which has a good list of recommended plants, plants to avoid, and some examples of verge treatments.
“The City of Campbelltown has approximately 500km of verges and is not able to develop and maintain them all, other than making them safe and accessible, and planting and managing street trees
Residents are encouraged to develop and maintain their verge area but there are guidelines and rules around how this is done so as to ensure safety and accessibility for all members of our community.”
They also have programs to help individual or groups to convert their verges.
There are two pages on their site:

and
