Surely you jest. A mean spirited government changing the definition of NBN to using the 120 year old copper network so they can do it cheap, then getting contractors/con-men/shysters to do everything from selling to installing. It might be a semi government body but they are renting out all services to private enterprise. Consequently worse services and coverage.
Doesn't help selling access to publicly paid for infrastructure to private companies to try and get competition. Private enterprise doesn't mean cheaper, it means they charge what they want because they can. Look at power, it's a long way dearer now than 20 years ago and there has been nothing spent on hardware/infrastructure. In fact power companies are talking of government upgrading major supply lines so they can sell more power.
It might have been less efficient but when power was sold through County Councils it was a lot cheaper, most towns had depots running maybe 30 vehicles, employing 100 people (Local). Now one vehicle services many towns, any work done on lines/poles is just minimum.
