One response to “Quigley, former CEO of NBN, attributes $15 b. cost blow out to Turnbull’s Multi Technology Mix.”
This is quite an extraordinary situation. If Quigley is correct and we are now paying up to $15 billion more for what appears to be an inferior system, what actions are possible? This is the sort of issue that warrants a thorough investigation before the rollout goes much further. The Abbott Government was inclined to splash public funds on Royal Commissions at the drop of a hat. If saving $15 billion is not worth a serious investigation, what is?
