Thanks for raising this with us.
We've checked your address with NBN Co and it is listed as Service Class 23. This means that the drop and wall plate is in place, but no NBN NTD box.
If you are unable to see any wall plate in the premises, then it will be checked by the attending NBN technician. They will assess your premises in order to perform the necessary installation that is needed to provide you the service.
We understand that the technician's appointment has been confirmed and further updates will be given once available.
