After the full cutover, Bowral exchange is likely to have no further function, and presumably could be sold off. Full cutover though will be many years away, when even the special services (ISDN, DDS, traffic-light-service-whatever-that-is, etc) that are preserved from the initial consumer-level migration have been replaced and moved on to a different network. > Presumably call handling & routing will be done at the POI with the remaining > path > to a subscriber just a matter of packet-switching data for a node.

No - call routing and handling will be done by the ISP's softswitch, likely to be located in the nearest capital city - I doubt there will be any voice-handling infrastructure in a node or POI, just effectively an Ethernet tunnel between NTU analog port and softswitch through the backhaul-POI-NNI-CVC-AVC-NTU chain.
