Prime Minister Scott Morrison has taken a swipe at his predecessor, Malcolm Turnbull, saying he should stay out of politics and will not be representing the Coalition government at any more international meetings.

Mr Turnbull appeared on behalf of the Coalition government at an international oceans conference in Indonesia earlier this week where he also criticised the Morrison government's decision to consider moving the Australian embassy from Tel Aviv to Jerusalem.

Mr Turnbull warned of a “very negative reaction” in Australia’s near neighbour and said in a meeting with Indonesian President Joko Widodo that no final decision on the embassy move had been taken. He also expressed confidence that the Indonesia-Australia free trade agreement would be signed in a matter of weeks, despite the diplomatic brouhaha.

Speaking on Thursday morning, Mr Morrison said Mr Turnbull would not be conducting any more international missions for his government.
