Re: NBN for average or high end users?
Maybe your question would be better off as NBN for high end users or NBN for high end users that are less than 300M away from box.
High end users pay more for their service thus subsidising the low end users. It's exactly the same effort to install and exactly the same hardware.
At some point fibre needs to run to the house and personally I'd rather see it done once properly than spending almost as much on a second rate system that will need to be ripped out and done again properly not that far down the track.
