Why NBN Co's FTTN Arguments Are A Crock

In a recent blog post, NBN Co attempted to justify why it is rolling out fibre to the node (FTTN) rather than fibre to the premises (FTTP). NBN Co says that FTTP is too expensive for Australia, claiming that Australia is not on a level playing field with other countries that have FTTP.

But NBN Co's commentary is misleading, and omits a number of key facts. A more careful and accurate examination of the facts shows that Australia is indeed comparable with other countries that have chosen FTTP.

Population density

NBN Co says that Australia's low population density is at the core of the problem. It correctly points out that Hong Kong, Tokyo, Singapore and Seoul have higher population densities, but goes on to compare the population density of Singapore with the average population density of the whole of Australia. NBN Co fails to mention that 90 per cent of Australians — those people originally targeted with FTTP under Labor's NBN — are in cities and towns with relatively high population densities.

A much more appropriate comparison would be with cities like Auckland, Lisbon or Stockholm, all of which have similar population densities to Sydney and Melbourne. Importantly, the citizens of Auckland, Lisbon and Stockholm enjoy access to state-of-the art FTTP broadband.

Rollout cost

NBN Co has been insisting for 4 years that the cost of rolling out FTTP in Australia remains constant at $4400 per premises. But many FTTP operators around the world have reduced the cost of FTTP by as much as 50 per cent by incorporating improved construction techniques. For example, in New Zealand, Chorus has reduced the costs of FTTP deployment by 44 per cent over the past few years, using a variety of approaches.

It is a nonsense for NBN Co to argue there are no improvements in FTTP construction costs by ignoring technology improvements and refusing to learn from what has happened in other countries.

The continuing successful rollout of FTTP in New Zealand by Chorus is clearly a thorn in the side of NBN Co. In the meantime, New Zealanders look at Australia's second-rate NBN in amazement. Chorus' corporate reports proudly point out that their costs for rolling out FTTP are much less that what NBN Co claims.

In the blog, NBN Co disparages Chorus' use of micro-trenching and other techniques for bringing the fibre into each home, rather than what they call "a properly constructed underground duct". NBN Co says: "this method does not protect the very fragile fibre as well as if it is safely inside a protected duct".

What NBN Co omits to mention is that modern optical fibre cables are not fragile, and there is widespread use of micro-trenching and other ductless methods in many other countries. It appears that NBN Co is reluctant to admit that FTTP deployment techniques are improving and that radical new approaches can have a significant impact on reducing costs.

Google Fiber

NBN Co points to Google Fiber in the USA as an example of a company that found it too expensive to build a FTTP network. They do not acknowledge that Google Fiber's situation is very different from NBN Co's situation in Australia. For a start, in the USA, multiple hybrid-fibre-coax (HFC) and FTTP companies compete with parallel distribution networks, much like the parallel HFC networks installed by Telstra and Optus in the 1990s. As the sole wholesale provider, NBN Co is free of these issues and therefore able to construct a network at a lower cost per customer.

As pointed out by NBN Co, much of the FTTP and HFC infrastructure in the USA is aerial, but this has caused headaches for Google Fiber. The big problem is that competing companies use the same utility poles for their cabling. Significant cost increases and delays can arise when a new company like Google Fiber wants to install its fibres on power poles that already have cables belonging to other companies attached to them and there is no free space for Google's cables.

Some cities in the USA tried to assist Google Fiber overcome the extra costs and delays by implementing rules, known as "one touch make ready" rules that would allow Google to move the competitors' cables to make space for Google's cables. But some of Google's incumbent competitors, Charter, Comcast and AT&T sued those cities and Google was left with no option other than suspend rolling out FTTP. It is expected that Google Fiber's FTTP rollout will resume when one touch make ready rules are implemented.

The key point here is that Google's decision to suspend its FTTP rollout resulted from legal action brought about by competitors, not by the inherent costs associated with FTTP. Google has stated that their costs for rolling out FTTP is about the same as upgrading an HFC network to DOCSIS 3.1. Using NBN Co's figures for FTTP and DOCSIS 3.1, this suggests that Google's FTTP rollout costs are about 50 per cent of NBN Co's claimed costs for FTTP.


NBN Co points out that Verizon in the USA has the ability to cherry pick high-margin, low-cost metropolitan areas, while NBN Co has to serve everyone. Again, it does not mention that as a monopoly provider, with no competing networks running in parallel, NBN Co is able to build a network at a lower cost per premises. It also fails to mention that Verizon provides FTTP to suburbs in the USA with population densities that are similar to Australian suburbs.

The upshot

Take away the misleading statements in the blog, add some important missing information, and it becomes clear that FTTP is now cheaper to roll out than ever, and the rate at which it is being rolled out around the world is accelerating. There is no good reason why Australia should not be enjoying FTTP. There are few better examples of how to embrace FTTP than in New Zealand. Chorus is efficiently getting on with the job of rolling out FTTP in New Zealand, while NBN Co seems to be fixated on finding excuses for why Australia is not able to do the same.

    There is no real correlation between the original plan and the shit storm we have now, so we are never going to get the NBN we were promised. When they are advertising a ping of nearly 600, intentionally or not, they are advertising the fact that they are out of control. All we can do is hope for something that at least gets us "all" onto fibre.

      In all fairness, Tony Abbot made a pre-election commitment that he was going to absolutely roger the NBN. But ya'll still voted for him because we couldn't stand another 4 years of backstabbing and infighting.

      Sure, nobody could've predicted the Libs were going to give us another 4 years of backstabbing and infighting, but the destruction of the NBN was a core LNP pre-election promise.

      The responsibility for the demise of the NBN rests firmly with the average Australian voter.

      I really wish ya'll had cared so much about it before you voted to 'ditch the bitch'.

        Ahem! I most certainly did not vote for Abbot, I can assure you of that!

    NBNCo's motto should be - Don't let the facts get in the way of a good story ..

    Why Rod Tucker's Arguments Are a Crock
    Rod Tucker should stick to his job at Melbourne Uni and let NBN get on with their job. The huge tax payer cost of the NBN partly rest's at Rod Tucker's feet along with other academics and ministerial advisors connected to the academic world at the time the NBN was first conceived.

    The tax payer should never have paid for this project and most of the overseas examples cited by Rod highlight this very point - no tax payer funds are being used!

    NBN is now more worried about metro Fixed Wireless Access (FWA) competition in the coming few years - further undermining their cost recovery. FTTN / FTTP /FTTH arguments are really a side-line issue to this far bigger issue for NBN now. As tax payers we should all be concerned about this.

    Rod and his fellow team of advisors created this mess in the first place and all we can do now is try to reduce and recover the extra-ordinary costs this project is costing all of us.

      What a load of old cobblers!

      The reason the nbn is in such a mess is because the Coalition government refused to heed the advice of the technical experts like Tucker. Instead, Abbott and Turnbull deliberately and criminally sabotaged the NBN for the incredibly childish purpose of just being different to Labor.
