The federal government is under renewed pressure to provide tougher scrutiny of its national broadband network.
While the opposition pushes for a Productivity Commission analysis of the $43 billion project, the Australian Greens are demanding the government release the network's business plan before parliament rises for the long summer break, AAP reported.
The coalition has yet to win the support of key lower house MPs for a cost-benefit analysis of the network, but it may be a different story in the Senate.

Greens communications spokesman Scott Ludlam says his party will seek Senate support for a demand that Communications Minister Stephen Conroy produce the network's 400-page business plan that he received last week.
"I think they have an obligation to put that material in the public domain while parliament is sitting, not afterwards," he told ABC Radio on Tuesday.
Senator Ludlam also wants the government to produce its formal response to an earlier implementation study.
"We'll be demanding the minister table both of those documents before the end of this week," he said.
Opposition communications spokesman Malcolm Turnbull is expecting his push for a cost-benefit analysis of the network will go to a parliamentary vote this week.
But it's not clear whether the coalition has sufficient support from the crossbench at this stage. Fairfax on Tuesday reported that key independents including independent Nick Xenophon were considering supporting Turnbull's push.
"We continue our discussions with the independents and they'll make their decision when it comes up to the vote," Mr Turnbull told ABC Radio.
