Two key independent MPs say there's little chance a future coalition government will be able to unwind major policies such as carbon pricing and the National Broadband Network (NBN).

Independent Senator, Nick Xenophon, has praised the Government for releasing the NBN Co business case summary and said it wouldn’t have happened without the Prime Minister’ s intervention.

The Gillard government has received a rebuff from key independents over its failure to release the business plan for its election centrepiece - the $43 billion National Broadband Network (NBN).

Key federal independent MP, Tony Windsor, won't back any move for a Productivity Commission analysis of the $43 billion National Broadband Network.

Former Treasurer, Peter Costello, has launched a scathing attack on the National Broadband Network (NBN), branding it “the National boondoggle Network”.

Former Optus executive and Liberal MP, Paul Fletcher, remains a key advisor to the Coalition on broadband, despite his role in helping craft its controversial policy during the election campaign.

Newly appointed Shadow Communications Minister, Malcolm Turnbull, has experience in the dial-up business, not the broadband industry, according to Communications Minister, Senator Stephen Conroy.

Opposition Leader, Tony Abbott, says one of Malcolm’s roles as the new Shadow Communications Minister will be to expose problems with Labor’s National Broadband Network project with the aim of wooing independent MPs back to the Coalition’s camp.
