Communications Minister Malcolm Turnbull will release a redacted version of the National Broadband Network (NBN) strategic review as early as next week, but not in time to comply with an order from the Senate.
Australian Greens senator Scott Ludlam has put forward a motion calling for Turnbull to table the document to the Senate before noon on Monday December 9.
However, the coalition has advised they will be withholding the document until after the deadline.
"The government needs a little more time ... to ensure that the information cannot advance the commercial interests of other parties over NBN Co," a letter tabled in the Senate on Thursday said.
Turnbull, who has received the working draft of the NBN report, told question time he will release the strategic review later in the week.
As the review contains information of the government's commercial interests it will be redacted.
The 60-day review, carried out by NBN Co under new chairman Ziggy Switkowski, looks into the feasibility and projected costs of the coalition's plans to have 25 megabits per second broadband service to all homes by 2016.
Switkowski told a Senate hearing last week the 2016 deadline was "very demanding".
The coalition plans to deliver a fibre-to-the-node NBN, a much slower but less expensive version of Labor's fibre-to-the-home plan.
