Turnbull, who has been under siege from all angles about his controversial plan for the NBN, said in question time today that the working draft of the NBN report has been delivered but still needs to be approved by the NBN Co board next week.
"We will be releasing shortly a strategic review which will spell out the facts, the objective facts and the truth about this project for the first time in its history," Turnbull told Parliament yesterday.
A spokesman for Turnbull told News Ltd that the government expects the report to be released by the end of the year, but any material that is deemed commercial in confidence would be redacted.
"The NBN Co has many sensitive commercial relationships and negotiations ahead of it, not least of which with Telstra, Optus and the various construction partners," the spokesman said in a statement.
"On the other hand, the government wishes to make as much of the review publicly available as possible in the interests of transparency."
He said the government has asked NBN Co for its advice on what material it believes should be redacted and will then make a judgment.
Interim NBN Co chief Ziggy Switkowski confirmed at a senate hearing recently that NBN construction would continue with Labor's FTTP rollout for now, while tech giant Microsoft has called for a "rethink" into debate around the benefits of Australia's biggest infrastructure project.
A 'National Day of Action' where voters presented petitions on CD-ROMs to MPs across Australia was deemed a failure however, with less than 20 people showing up at Malcolm Turnbull's office to call for a FTTP, rather than FTTN, broadband network.
