The Trans-Pacific-Partnership risks falling into a complex "noodle bowl" of trade agreements unless Australia's bilaterals with eight of the countries are torn up, a leading business lobby group says, as early resistance threatens to stop the deal being ratified in Parliament.

Under a proposal from the Australian Chamber of Commerce and Industry, bilateral trade agreements with Japan, Chile, Singapore, Malaysia, Vietnam and Brunei would be thrown in the bin and replaced with the broad sweeping powers of the so-called TPP11.

The revival of the deal, reached overnight in Tokyo, was followed on Wednesday by widespread calls for a full Productivity Commission review of its merits and the inadvertent release of key details of TPP11 by the Prime Minister's Office that shed some light on the otherwise vague details of the agreement.

Foreign investments from private investors worth under $1 billion from countries including Mexico, Canada and Malaysia would no longer be subject to Foreign Investment Review Board approval, while Labor market testing in some categories would also be waived for countries such as Singapore and Mexico, potentially setting up a clash with the unions.
