The long-awaited text of the landmark trade deal called the Trans-Pacific Partnership (TPP) has been released to the public for the first time.
The text still has to be translated into the languages of the signatories.
The TPP is one of the world's most extensive trade agreements, bringing together 12 Pacific rim countries, including the US and Japan.
The deal was struck last month after five years of tense negotiations, but continues to face fierce opposition.
It also must still be ratified by lawmakers in each member country and some of the countries involved also need it to undergo a legal review.
Critics have said the deal is biased towards corporations, and does not cover climate change concerns, among several other issues.
Public Citizen's Global Trade Watch said on Thursday the final text has revealed details about the deal that were worse than expected.
On Thursday, US President Barack Obama formally notified Congress of his intent to sign the landmark trade deal, but he must gather support in Washington to ensure the deal can be formally approved.
Last month, US presidential hopeful Hillary Clinton came out against the TPP, saying she was not in favour of what she had learned about it. She joins rivals for the Democratic presidential nomination, Martin O'Malley and Bernie Sanders in her stance against the deal.
In Australia, the country's trade and investment minister Andrew Robb said the release of the text to the public for the first time honoured a commitment from all member countries to do so before it was officially signed.
"Today's release... provides the Australian public with an opportunity to examine the text and more fully understand any areas of the negotiation that are of interest to them," Mr Robb said.
The member countries of the TPP account for some 40% of the global economy and include Australia, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore, the United States and Vietnam.
The deal cuts trade tariffs and sets common standards in trade for all the countries.
