The NBN is active in much of Oyster Cove. However, there are still some areas which currently has the designation of not currently available with the comment that the NBN has not started in this area. Since the change of government 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 word on when the NBN will be completed in the Oyster Cove area.
