The way I understand it, if you are in a house you will get NBN FTTH (fibre to the home) for free. The same might apply for some types of MDUs (eg townhouses) where an individual connection is possible. But if you live in an apartment block, and in some urban areas over 80% of people do, then FTTH will not be free for you. The OC will have to pay for the internal installation which will have to be done to NBN Co’s exact specifications.
And once the NBN comes into an apartment’s area, the OC will have little choice but to connected it because all the existing phone and internet services will be switched off 18 months later.
So the connection is hardly going to be cost equitable. Apartment owners will have to pay for what home owners can get for free.
