A period of some hours over at Independent Australia isn't sufficient to get a comment moderated, so my comment is here.
I'm pro-NBN, but I like to defend it with facts. So while it's good to see Independent Australia chiming in on the debate, here, there are some points I'd like to correct.
1. "Turnbull’s go to line that “[NBN Co] has only had about 5,000 connected”. Having studied the business plan, I see nowhere that Turnbull could possibly have gotten this figure from".
It didn't come from the business plan. Mike Quigley used a similar number here.
"In terms of activations, we now have close to 5½ thousand premises connected to the NBN across the country."
This was in February and is presumably obsolete, and anyhow included satellite (which is even worse for the fibre case).
My guess is that a statement like this has become part of Turnbull's armoury - even if it is now out-of-date.
2. "...the bandwidth falloff for VDSL2 Profile 8 (more than likely what will be deployed to keep costs down & deliver service to 1kilometre) not even making it to 80Mbps at the DSLAM (Digital Subscriber Line Access Multiplexer, i.e. Exchange Equipment)."
That probably needs a re-write. The DSLAM is where the bandwidth is delivered from. So it's hard to discern the point that's being made.
3. "...a minimum of two pairs (bonded) are required to run the service, and one pair to run a telephone line." (my emphasis)
The phone line runs on one of the pairs, just as it can with ADSL: the lowest frequencies are reserved for voice (described as USO services in the standards documents). The broadband signal starts above 100 kHz.
4. "The requirements for lead-ins is that two pairs be installed to the first socket in the premises, the Telstra/Optus networks are both designed with this in mind, leaving little room for two pairs to be taken up by a VDSL2 service."
Optus doesn't run a twisted pair copper network. Its broadband services are delivered over HFC, or over Telstra copper - as are its fixed line voice services.
5. "there would have to be, at the least, a new copper pair for every premises connected to the network."
That depends. Many houses have two pairs installed, not because they were needed: merely because years ago, that's what Telstra did, just in case one failed. What we don't know - among the many things we don't know about the copper network - is how many houses have two usable pairs installed.
So what's the point to me correcting this?
The NBN is a political debate - which means that technical errors get exploited to make a political point. It's not a good idea to put weapons in the hands of your opponent.
