Foreign Minister Julie Bishop will bring every ambassador back to Australia in an unprecedented move designed to help shape the final components of the Turnbull government's new foreign policy.

In an Australian-first step, 113 heads of mission - which includes the nation's ambassadors, high commissioners and consuls-general - will return for three days next month, as the government looks to reset how Australia navigates its foreign, trade and development policies on the global stage.

Every head of mission, with the exception of a few whose terms are about to expire, will meet in Canberra for a two-day meeting with Prime Minister Malcolm Turnbull, Ms Bishop and Trade Minister Steven Ciobo, as well as a representative from Labor, to contribute to the long-awaited Foreign Policy White Paper, due to be delivered later this year.

The paper is being developed as Australia attempts to steer a course through an increasingly turbulent foreign landscape, which includes the Trump presidency, tensions over the South China Sea, anti-trade sentiment and global terrorism challenges.
