Draft laws to cement a massive Pacific trade deal are set to pass parliament with Labor's support, sparking criticism from independent MPs and a major union.
Labor supports the legislation which would implement the Trans-Pacific Partnership, a trade pact which now includes 11 countries after the US withdrew its support under President Donald Trump.
While Labor has major gripes with several aspects of the deal, it says it will support the legislation regardless, promising to make changes if successful at the next federal election.
Opposition trade spokesman Jason Clare told parliament on Thursday independent economic analysis of the pact shows it doesn't benefit all sectors equally, but no sectors would be worse off.
Labor says the deal would increase exports by $29.9 billion, lift investment by $7.8 billion and boost Australia's national income by $15.6 billion by 2030.
"There's agreement it will provide relatively modest benefits in the short-term, with potential for more significant economic gains in the long-term if more countries in the region sign up," Mr Clare said.
Labor disagrees with provisions which allow workers from Canada, Peru, Mexico, Brunei, Malaysia, and Vietnam to be employed in Australia without first checking if a local could do the job.
The party also opposes investor-state dispute settlement provisions, which allow foreign companies to sue the government, saying they threaten sovereignty.
Liberal MP Trent Zimmerman says the provisions are a standard inclusion in trade deals and have had no negative effect on government.
But Greens MP Adam Bandt says the deal will hurt both local and foreign workers.
"The Labor party stands condemned today. No matter what their policy is, they will vote for big business every time," he told parliament.
Independent MP Bob Katter is livid at the government for its support of free trade, saying it has destroyed industries in Australia because local products can't compete with cheaper imports.
Mr Katter vowed to "fight the TPP until the very end".
Central Alliance MP Rebekha Sharkie says unless the deal's significant flaws are addressed, her Senate colleagues won't support it.
She is calling for evidence and analysis on the benefits of the deal, urging Labor to work with the crossbench to fix issues now.
Australian Manufacturing Workers Union secretary Paul Bastian said the deal would be a disaster for local workers and was a breach of Labor policy as it allows an easier flow of foreign workers into the country.
The deal will provide economic security and prevent a situation similar to the trade war between the US and China, Nationals MP Keith Pitt says.
