Links to the rest of the world via optical fibre cable already installed or about to be installed about 25terabit/second.
The rest that you mention is not a CBA but a business case. NBN Co is releasing that about now. There is just too much uncertainty:
To highlight the nature of the problem – imagine doing a CBA on the post-war Post Master General’s roll out of what became the bulk of our existing copper telephony network. PMG spent 42 million pound to roll that out – about 10 billion in today’s dollars.
If a CBA was undertaken on the project back then, one of the benefits that could not have been included in the mix was the internet because it was yet to be invented (let alone fax, or basic data exchange before that etc) – even though if you have a DSL connection, there’s a good chance you are still using the original PMG cable system to read this very post. Even with the application of a standard discount rate applied to the value of the economic activity that the PMG cable side of the net has generated over the last 15 years in Australia (and fax and basic data exchange before that), it would still have been a not insignificant benefit in any original CBA done on the project if the creation of the internet and its economic consequences could have been foreseen at the time.

Telecommuting will be one of the real benefits of the NBN IMHO. BUT the rate of takeup of telecommuting depends on things like the petrol price and the (possible) introduction of state congestion taxes. Want to guess the petrol price on 26 Oct 2020 SN? This benefit of the NBN may have to wait for like 10 years because the major western economies are embracing policies—austerity—that will see full-blown Depression rule the US/UK/Europe for a decade, maybe more, keeping petrol prices lower. Still want to guess that petrol price SN?
When petrol was at $1.50/L there was a slight move to public transport. With the NBN in place a move in the petrol price to $1.50-2.00 will see a major shift to telecommuting. Care to predict when that will be, SN?
When telecommuting becomes widespread will our cities still grow like now, with outer suburbs with few facilities a accepted feature or will people move to regions where real estate is cheaper, lifestyles far superior and crime much lower? What will be the costs and benefits of that SN? Stuff like fast rail links back to the capital will be needed—care to do a CBA on rail right now SN? Could one of the main benefits of the NBN be reduced pollution, reduced GHG emissions, reduced road toll?
Will cloud computing take off because the NBN makes it possible or will security concerns mean it is never much more than an idea? This is something in the immediate future and we don’t yet know if the cloud will be reality or not. Care to do a CBA on cloud computing right now SN?
This stuff is like a couple of years away as areas start to get wired with FO. What benefits or costs will there be in 10, 20 years?
What you are really asking SN is an implementation study and a business case. The former has been done and the latter is being released right now.
One of the casualties of the NBN could be newspapers. Even now, quality blogs like Grog’s Gamut or some of the Crikey blogs (Pollytics and Poll Bludger) are better value than the MSM—on Poll Bludger it was worked out that the Gretch email was fake even before the Daily Telegraph published the faked email on its front page. FTA TV too will at least change, migrating to the net. Costs and benefits? Maybe reducing GHG emissions is the big benefit of the NBN?
Mobile telephony will take a big hit as it cannot compete with video phone calls via the NBN and is much, much more expensive. How do we quantify now the health benefits of that, when cancer linked to EM radiation is hotly disputed? (and disguised IMHO.)
