FORMER head of Telstra Ziggy Switkowski, who left the company under a cloud, will head up the Abbott Government's new era for the NBN Co.
Communications Minister Malcolm Turnbull said Mr Switkowski would hold an executive chairman role on a board of just three members.
His role at the helm of both the board and senior management would be temporary, while the government seeks a new chief executive to replace Mike Quigley.
Mr Turnbull defended Mr Switkowski's record as an experience telecom executive, despite questions about how successful his term was at the helm of Telstra.
He said he did not intend to comment on an "orgy of speculation" regarding the possible of appointment of former Leighton executive Wal King to the board.
The minister said the new three-person board would include Dr Kerry Schott and Alison Lanley, with the only board member not to have resigned, Brad Orgill, fired from his position.
Following a Cabinet meeting in Canberra on Thursday, Mr Turnbull also released details of the scope of the six-month "strategic review" of the NBN roll-out.
Mr Turnbull said he remained of an open mind to the extent and technology to be used in the remaining NBN roll-out.
He said the review would not be restricted by the Coalition's policies leading into the election, but would focus on a cost-benefit analysis designed to save the taxpayer.
However, he would not comment on whether the remaining roll-out would centre on Labor's fibre-to-the-home, or the Coalition's fibre-to-the-node plans.
The terms of reference for the review will also consider "alternative strategies" for the economic viability of the roll-out, which could include a more limited roll-out in some areas.
Mr Turnbull said he would wait for the results of the review before officially considering any changes to the nature of coverage of the broadband network.
