Welcome to the community!
Thanks for raising this to us. Yes, we do ship the NBN box and the modem/router separately. We're able to locate the account using the community details. I can see that you have been in contact with one of our Provisioning Case Manager and discussed details of the NBN NCD box.
Let me know should you require further assistance.
We have received our NBN modem but require the NCD modem as well.
Is this something we need to order separately?
