Shadow communications minister Jason Clare has called for transparency around the NBN after it was revealed external oversight of the corporate plan had been scrapped under communications minister Malcolm Turnbull.
In hearings of the Senate Select Committee on the NBN, the secretary of the department of communications, Drew Clarke, admitted that the independent review process had been killed off and that the corporate plan would now be reviewed by the department of finance and the department of communications.
Clarke told the committee the review of the current corporate plan (2014-17 corporate plan), had been done in a "different methodology".
"The different methodology has involved the two departments leading the process."
Under the previous government, NBN Co's corporate plans were subject to independent external oversight by reputable firms like Greenhill Caliburn, KPMG or Ernest & Young.
Clare has also called for Turnbull to release for the corporate plan after NBN Co chief executive Bill Morrow told the senate select committee the plan had been sitting on Turnbull's desk for some time.
"If Malcolm Turnbull wants to keep his promise to be 'completely transparent', he should reverse the decision to scrap external oversight of the Corporate Plan and release the corporate plan that is sitting on his desk," he said.
