When my home had NBN we did not pay for the cable in the house, but I have an apartment and recently tenant told me NBN cable is out side the apartment and NBN provider told her that landlord needs to pay for an electrician to put cable inside the apartment and put a socket as well before they can come back to put NBN.
Is anyone else has to pay for electrician to run the cable into and put a socket as well?
It depends on the technology being installed to if any extra internal cable needs to be installed. It also depends on if it's a brand new apartment or old. Also depends on the technician that came out if they are willing to put in the work for the low pay nbn give them. Close to 98% of the people working on the nbn network are contractors so if your apartment will need 5 hours of work to complete then a technician basically won't do it because that's five other jobs they won't get paid to do.
When it comes to internal cable in apartments it will normally get kicked over to body corporate due to the time needed
