It would be very unlikely that your complex will be missed.
NBN are working at getting all people connected and to remove them from traditional ADSL services.
I looked up your ADSL service and was pleased to see that you actually have a very stable and speedy ADSL service that exceeds in speed the base plan on NBN of 12M/1M.
At least whilst you are waiting you currently have good Internet.
Sorry I cant offer you anymore information.
