For your amusement Myths, I'll just say nothing is bullet proof when ultimately confronted with the reality of a Labor disaster.
Sorry, but it is impossible to blame Labor for the cost blowout of rolling out FTTN. The coalition knew how much had been injected into NBN Co up to now, and they knew that they would continue FTTP until 2015ish.
There is nothing the ALP have done to date which makes FTTN any more expensive than Turnbull knew it would be months ago. We all said they were dreaming with regards to their cost and timetable, and it turns out we were right.
