With forced council mergers a big topic in communities across sydney, I found an article from 1966 when Epping wanted to create its own council to resolve the situation where the suburb was divided amongst three councils - Parramatta, Hornsby and Ryde. This was seen as causing headaches for locals. The existing councils opposed the idea. It never got off the ground, but under the NSW Government's policy of forced council mergers, the entire suburb of Epping was incorporated into the City of Parramatta Council in May 2016.
