NBN Installation has different Service Class types. I've managed to locate your account using your Community details and found out that your service is under Service Class 12 for the NBN FTTN service.
This means that the status of copper is known; jumpering may be required at the node.
I have raised your concern to our Provisioning Team so they can get in touch with you for updates.
