Adding open data to OpenStreetMap

Hi forum.

Somewhat related to @nishitaparmar’s thread - Do you need more Local Government Data? - how widespread is the use of OpenStreetMap in local government in WA (either as a simple basemap or as a source of data)?

For those LGAs that do use it, do you add any of your open data back to OSM? If not, have you considered doing so?
