NBN Installation has different Service Class types. Yours is under Service Class 12 which means that the status of the copper line is known and jumpering may be required at the Node.
An installation technician is responsible on making sure that the first available phone socket is activated however, they also advise customers whether a new socket is required or if the phone socket is available to use.
In your case, it should be the landlord's responsibility to ensure that a phone socket is ready to use. If it's not, then we require our customers to hire a private technician as it deals with the wiring which an install tech is not trained for.
Please do inform us once the work is done so that the Case Manager can do a follow through with NBN to activate your service.
