At 12am on Sunday, one of the largest and most fraught trade deals in world history will come into effect, with Australia and five other countries importing and exporting under the rules of the TPP-11, formally called the Comprehensive and Progressive Agreement for Trans-Pacific Partnership.

The midnight launch of the agreement comes after more than a decade of tortured and at times perilous negotiations, including President Donald Trump's high-profile withdrawal in 2017, which stripped the TPP of the American economic might that had accounted for 60 per cent of the original bloc's combined GDP.

Trade Minister Simon Birmingham said the TPP-11 was a "major win" for Australian producers and businesses, who will have boosted access to Canadian, Japanese, Mexican, Singaporean and New Zealand markets from December 30. It will come into force for Vietnam on January 19, with Brunei, Chile, Malaysia and Peru following after they ratify the agreement.

“Australia has an international reputation for its premium and high-quality produce and now it will be enjoyed by more people around the world," said Senator Birmingham. "The opportunities are vast, from more Victorian wine and cheese being enjoyed on the slopes of Whistler, to more NSW prime beef being served up in Japan’s world-class restaurants.”
