If my memory serves me correctly once the NBN becomes available in an area residents and businesses have 18 months to connect before existing landline services are disconnected.
Yes, this is the case for the 93% of Australian premises connected to the nbn™ network via a fixed line technology. You can see where fixed line technologies have been installed in the nbn™ rollout map. We recommend you migrate your services over to the nbn™ network well before they are switched off, which occurs 18 months after the nbn™ network is switched on in your area.
