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).

The NBN will enable more people to "work where they live", according to Prime Minister Julia Gillard, who attended the opening of the NBN Co network on the mainland in Armidale today where the home work possibilities were showcased at length.

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

Prime Minister Julia Gillard has invited the group of three returning independent MPs to meet directly with NBN Co chief executive Mike Quigley, as the trio continue to push for more information about Labor's National Broadband Network policy.

The National Broadband Network is likely to play a key role in the balance of power with the independents and Greens supportive of the project, however, mandatory Internet filtering remains a bugbear that many of the elected MPs continue to oppose.
