Independent Senator Nick Xenophon eventually acceded in supporting the National Broadband Network legislation that would pave for the way for the structural partitioning of Telstra Corporation, which the federal government maintained is crucial to full roll out of NBN.

The maverick lawmaker finally gave his yes on the NBN bill as the Labor-led government tossed its commitment to release the controversial 400-page NBN business plan but not without insisting a compromise, which Senator Xenophon had accepted anyway.

In exchange for his support into separating the giant telecommunication firm's wholesale and retail division, Prime Minister Julia Gillard offered to release not the whole copy of the debated NBN plan but a mere 50-page brief of the lengthier broadband blueprint.

Also, Senator Xenophon was accorded a formal orientation on the business plan by NBN Co chief Mike Quigley with the additional premium of sinking his teeth on the $43 billion federal project as Ms Gillard gave assurance to the independent senator that a joint parliamentary committee would be tasked to supervise the NBN roll out.

Obviously please with the deal, Senator Xenophon expressed his appreciation by thanking Ms Gillard on her commitment to release the NBN business plan's summary, which should be forwarded to the Parliament on Wednesday afternoon.

The agreement proved to be a win-win compromise for both the prime minister and the Coalition as the former could now look forward for its NBN bill breezing through the parliament while latter has gotten its wish to appreciate the NBN business plan before the long summer break for all lawmakers.

Analysts said that Senator Xenophon's vote virtually assured the passage of the NBN legislation as the federal government needs only to win the approval of Independent Senator Steve Fielding, following the earlier backing announced by the Australian Greens for the bill.

While Senator Fielding has yet to mouth his final decision on the NBN question, Ms Gillard appeared already upbeat on the prospect of the NBN's realisation as she allowed that government efforts are continuing and negotiations with MPs are being sustained to win their support on the NBN project and the attending legislation that would clear all the roadblocks for its successful implementation.

The deal came as the government struggled to muster sufficient cross-party support on the NBN project and legislation with numerous lawmakers adamant on their demands that the NBN blueprint be released prior to the long session lull of the federal parliament.

Ms Gillard appeared to have surrendered some grounds, according to analysts, as she decided to bend forward in offering the release of the NBN brief, conceding that after some serious discussions "it is possible to publicly release carefully selected materials which answer some of their (lawmakers) key questions."
