NBN is suggesting that users would get an average of just over 10Kb/s of bandwidth consumption.  I am saying on a 1TB (or 1,000GB) plan, which is where we are today and pushing beyond that in the next few years, where the users actually use 1,000GB they will also use an *average* of approximately 3Mb/s x $21/Mbps/month.

Er, *NBNco* are suggesting that (see the pricing PDF), I agree 100:1 is
probably completely unacceptable, although only a few years ago we were
doing ~4-8:1 *at peak* with education users.

Some oversubscription is obviously needed to have at all acceptable
pricing in the retail market.

Not being in the retail ISP business I have no idea what that number
would be.

Obviously you gain through users not using their bandwidth, but the reality is you can deploy a DSL tail with unlimited backhaul in metro for less than just a tail access on NBN without backhaul to even the nearest PoI, let alone to the PoP.

Given that it's not a cost in the NBN side I think it's worth at least
mentioning.
