The Trans-Pacific trade deal signed by Australia and 10 other countries last week could boost Australian exports by $30 billion and increase real GDP by $18 billion by 2030, according to economic modelling released by industry groups endorsing the deal.

A policy brief released in support of last week's deal by nine industry groups - including the Minerals Council, the Business Council, Australian Industry Group and the Financial Services Council – says the TPP-11 deal will "improve the ability of Australian businesses to export to countries across the Asia-Pacific, including Japan, Malaysia, Vietnam, Singapore, Canada, Mexico, Peru and Chile".
