Prime Minister Kevin Rudd says nothing will stand in the way of the government building the National Broadband Network.
The long-awaited implementation study into the NBN will be released at 11.30am.
The $25 million study by consultancy group McKinsey and KPMG will be released two months after it was received by the Federal Government.
"The government is determined to build a national broadband network and will not let anything get in its way," Mr Rudd told reporters in Whittlesea, north of Melbourne.
The successful rollout of the NBN was crucial to the future of many sectors of the economy.
"It benefits the economy, it benefits business, it benefits the provision of decent health information right around the country.
"It benefits ... a whole lot of areas we haven't even thought of yet."
The study is believed to back the economic case for the NBN, with or without the involvement of Telstra, as the government requested.
It is also expected to show the cost of building the network will be much less than the $43 billion initially earmarked for the project.
The study will be released by Communications Minister Stephen Conroy and Finance Minister Lindsay Tanner in Canberra.
