The largest costs in deploying this network are in the civil works
There are many choices and factors that can have a large
impact on the costs of deployment -- the aerial versus underground
mix, availability of duct space, lead-in distances, availability of
migration costs... the list to be considered is long.
Estimating the costs associated with each of these factors is not
an easy exercise.
In preparing a business plan the two factors that dominate
the estimates are the deployment costs I have just mentioned and
the revenue plan, which is also dependent on a large number of

no readily available database we can use.
But we do have some sophisticated geospatial tools, which
allow us to make some reasonable estimates.
This next Slide (9) is a picture from one such tool showing
the distribution of Geo-coded National Address Files (GNAFs)
The red areas represent the 91 per cent of premises that are
served by a pillar. These are in 8 per cent of the land area.
The green areas represent the 9 per cent of the premises that are
served directly from the local exchange -- possibly over a very long
distance using long copper runs or a rural radio system. This 9 per
cent is in the remaining 92 per cent of the land area.
It is possible to zoom in on this map and see the occasional
little green dot that represents another premise.
Spending a few minutes playing with this tool gives you an
appreciation for the remoteness of much of Australia and the extent
of the build we will be doing.
As you would expect, we are taking all the steps necessary to
prepare for this very large civil construction job.
There are discussions taking place now regarding access to
critical infrastructure such as ducts and poles.
capability of the Australian construction industry in getting this job
Once the build is underway we will be dealing with, in close
cooperation with service providers, the complex task of migrating
This needs a good deal of coordination between activities at
the premise, activities in the local exchange, and activities within
the databases and systems.
There is a considerable amount of work to be done in the
preparation of all the potential migration scenarios, and that work
is now underway.
There are many more issues on which we are currently working

So let me conclude.
In being interviewed for the role of the CEO of NBN Co back
in July 2009 it became apparent to me that the Government had a
clear vision of the economic and social advantages for the nation
would be needed and the right approach for getting this complex
So it was with some enthusiasm that I accepted the role to
lead NBN Co.
I believe I can speak for the whole NBN Co team in saying it
is a privilege to be associated with this nation-building initiative
of the Rudd Government.
