Australia's free trade deal with China is poised to pass through the parliament by the end of next week's four-day sitting.
The enabling laws have been made a priority for Monday in the Senate, having passed the lower house in the previous sitting.
Labor has agreed to back the bill in the Senate after the government delivered what Opposition Leader Bill Shorten described as "proper" legal safeguards for Australian jobs.
The government agreed to put into regulation labour market testing for jobs on major projects and the setting of the "market salary rate" for 457 visa workers at the applicable enterprise bargaining agreement rate.
Foreign workers will also have to obtain an occupational licence within 90 days to receive a 457 visa.
Two Senate inquiry reports released on Friday endorsed the deal.
One report, looking at the enabling bills themselves, noted the free trade agreement would result in a $4.15 billion drop in tariff revenue over the next four years.
However, the second-round effects from increased economic activity made the deal worthwhile, the report said.
A second report into the broader implications of the deal said greater safeguards should be considered in the next review of the FTA to reduce the risk of the government being sued by foreign companies using the investor-state dispute settlement mechanism.
The lower house will kick off on Monday with private member's business and continue debate on changes to the means testing of youth payments.
The government has also listed its controversial changes to strip dual nationals of their Australian citizenship if they are suspected of supporting terrorism.
