NBN analysis almost useless: ACCC chief

Graeme Samuel, the chairman of the Australian Competition & Consumer Commission (ACCC), has questioned the value of any cost-benefit analysis of the federal government's $43 billion National Broadband Network (NBN).

Competition watchdog chief’s comments emerged as Malcolm Turnbull, the spokesman for opposition communications, is reportedly preparing to introduce a private member's bill for an analysis of the NBN.

In an interview with the Radio National Breakfast, Mr. Samuel said that so many assumptions would be required, which would make cost-benefit analysis almost useless.

Speaking on the topic, he said, "Even the best economists in the world will tell you that if the assumptions are being queried, what you do is you raise a whole range of scepticism over the value of the cost-benefit analysis.”

Meanwhile, Mr. Turnbull said that he was not interested in bringing down the NBN.

At the time of appointment to the communications portfolio, Mr. Turnbull was assigned with a task of demolishing the NBN.

But Mr. Turnbull said he was interested to make sure that the NBN was given full scrutiny and real accountability. He added that he wanted the NBN to be the fastest and the most efficient way to achieve wider availability of broadband across the country.
