When is the NBN coming to Lyons?

The building of the NBN has not commenced in Lyons or in its surrounding suburbs. Since the change of goverment in September of 2013 the NBN website has been a lot less informative and they only provide details of where there is build preparation, where the build has commenced and where service is available via a shaded map. However, there is no detail in regard to dates of when the stages of the service are likely to be completed. So there is no timeline as to when the NBN will be coming to Lyons.
