An application will need to be made to NBN as they are the network owner. As of 1st July 2019 Telstra has announced they will not be accepting applications as the NBN rollout is within 12 months of completion. Registration with NBN will be made in order to obtain a provisioning letter in accordance with the VC-81 legislation. Please be aware that you will be able to access the NBN network once the roll-out has been completed to your address. If you have paid your NBN invoice, connections are still dependent on the completion of the NBN roll-out.
