ACCC says to Optus, Why close a perfectly good network???

With the Optus network passing some 2.4 million potential customers, and serviceing over 500,000 of them, the ACCC is wondering why close a network in perfectly good working order.
Optus need to clearance from the ACCC, before it and NBN Co., can go ahead with the transfer of Optus's customers to NBN Co. for $800 Million dollars.
I hope the Commission take little notice of the point NBN made, about the network closure would give greater certainty to revenue projections for the NBN. Or their point that the take up of people using the NBN would increase. Isn't that what happens when you takeout opposition to a manopoly???
