I so wish that I could find a commentator who had both the breadth (ie,
technical and economic) and independence (both perceived and actual) as
to give the world a truly independent assessment of the NBN.
Even people who are well-informed on other matters get important details
wrong, as in the article below. This, combined with intractable
partisanship, has completely polluted the NBN debate.

1. The almost universal belief that the NBN is only about consumer
Internet under-estimates its value. It can also connect businesses, and
wholesale facilities; and it would carry traffic other than that
destined for the Internet.
2. Whatever speed the port is capable of, the consumer buys what they
want. The "headline" speed leads people to underestimate activation -
"nobody will activate if they're happy with 24 Mbps".

RC: "Adoption rate" is used in a sloppy fashion, given that the purpose
of the NBN is to replace the copper entirely. And note that Mr Brennan's
earlier assumption (that the NBN is just for Internet access) has crept
into his financial calculations - ie, the only income from the NBN is
for broadband access.
If, for example, we assume connection of all homes and businesses in the
footprint (the intention of the network), carrying all traffic types
(including mobile via connection to base stations), the equation changes.
As for the 15 year lifespan of capital equipment: this is equally true
of DSLAMs, wireless base stations, phone switches or softswitches -
neither operational costs nor capital equipment refresh are unique to

Ignoring the maths, this last sentence is critical. I agree: if it were
"worth" supplying fibre in a business sense, it would have happened long
ago (and we would be trying to fight a Telstra monopoly over the fibre!).
But we return to the core assumption about the NBN's customers - that it
only supplies Internet access and therefore can only obtain income from
that part of the telecommunications market.

This number is simply opaque: we cannot evaluate whether it's right or
wrong, so it has to be ignored. The point is valid (but that's why NBN
Co went to gigabit at the start - to skip one upgrade cycle), but it's
valid of any and every telecommunications network.

Here, I agree with Brennan, but with this caveat: you can't assess the
cost of applications that don't exist today. The cost of building the
NBN is assessable: the opportunity cost of not building it is not.

As I mentioned earlier, except for the headline figure, which is smaller
than the NBN, all of the criticisms of the NBN (replacement,
depreciation, cost of capital, ongoing operational costs) apply to all
