Competing Labor and Coalition NBN policies explained with a simple analogy

The Conversation on the subject of access to high speed optic cable internet connections, 22 August 2013:

If all this technical explanation is confusing, here’s a way to think about how both policies work. Suppose our major roads were sealed, minor roads were gravel, and access roads to homes were dirt. The ALP’s policy is like having all roads sealed, with 93% of access roads being sealed and the remaining 7% being upgraded to gravel. The Coalition’s policy is like having all minor roads sealed, but access roads will only be sealed if this is cheaper than gravel. If you want a sealed road to your home, you are welcome to pay for it yourself.
