I just got the NBN installed the other day(insane speeds, at a very high monthly price). The technician was at my house several times and his opinion as a contractor on the ground level is that no one at the top is aware of the impracticality of scaling the home installation in the time frame they are proposing. Furthermore, many people do not yet require such high speeds but are having it installed just because they are not required to pay for the installation, especially older folk who don’t understand what they are being ask to sign up for. There is a massive disconnect between who need such services (and what type of services at what cost) and what sounds good on a policy paper and in a press briefing.
