Television reception is a basic amenity, like a phone line. If there is no television reception, or unsatisfactory television reception, then the Owners Corporation has an obligation to provide it/fix the problem. It doesn’t matter if some owners don’t want it, if an owner made an application to the CTTT, I believe that the OC would be required to do it.
In terms of digital television, if a strata scheme has not upgraded their antenna to receive digital signals, then they should do that prior to the analogue system being turned off.
In the case of Foxtel, if certain owners want it, then they can pay for installation to their lots.
