Have anyone checked their address with NBN regarding availability ??
Have anyone with an NBN box attached to their house checked if it is recognised as being there ??
.
A relative has moved into a retirement unit, that is attached to a Caravan Park, there is a NBN box attached, and all 14 units have a box, yet no matter what provider, they must have an exact address for NBN in order to go on the NBN..... not one of the units are recognised, with Telstra telling them it has been happening ever since it was introduced, whichever technician worked on it that day only has to have failed to add the correct address for all the infrastructure to be left idol and unable to be used.
So much for our Government..... throw all the dollars at it, and no one can access it.
.
Anyone had this problem ??

Might be something for Albo to research whilst he is confined for the next 7 days
