It's also worth pointing that the build cost is being spread over ten
years, and the actual lifespan of the network is often stated as 50 to 100

Given 50 years - $98 per household per year.  Even if costs double, an
absolute bargain for the resulting infrastructure.

The NBNCo's business plan also states that the company will be debt free by
about 2030, at which point the company will be returning $2-3 billion a
year directly into the Government budget.

Aurora Energy (Tasmanian government owned energy distribution/retail
company) did trials of both FTTH and BPL (broadband over powerlines) about
ten years ago now; it was the outcomes of these trials that prompted the
Tasmanian Government to submit a proposal of a statewide FTTH network to
the Federal Government in 2007/08; and it was this proposal which resulted
in the Federal Government deciding to build a National FTTH network in
2009.  So in a very indirect manner, this option was eliminated very early
in the process of the NBN!
