Thats exactly it, I think that it should have been done a long long time ago also, but the other motivation is that everywhere is down to the last sets of copper pairs and they're only a micron thick. I was a boarding master at my previous school, the copper was all decayed and they layed a fibre backbone through the whole place and the tapped into the internet provider directly for the speed.
Personally, I cant wait for the NBN to roll out. When my house was built it was done with a spare conduit to the road for the cable to come through. I dont live in town or in a city and so ADSL isn't an option. Sat is expensive and I understand slow, through the microwave dish or whatever it is is also really expensive so the economical alternative is through NextG. Sounds fantastic as whatever lightening speed it is meant to deliver, but the reality is that it is a slow POS system that pretty much jams up at peak times ie between about 7.30-8.45pm every night. Cable to the house cant come fast enough out here!
