The Turnbull Government will take a rejigged leadership team into 2018, with a new Attorney-General replacing George Brandis and a new Home Office led by Peter Dutton driving policy on national security.
The prime minister announced the Christmas-week cabinet reshuffle on Tuesday afternoon.
George Brandis has resigned as Attorney-General and will be replaced by the former Social Services minister Christian Porter.
Mr Turnbull confirmed he would recommend Senator Brandis for a new position as Australia’s High Commissioner to the UK "early in the new year".
He praised Senator Brandis' time in office and said new foreign interference laws introduced in the final week of parliament for this year would be an "important part of his legacy".
Immigration Minister Peter Dutton will step up to become the Minister for Home Affairs, responsible for national security, as was flagged earlier in the year.
Michaelia Cash, already Employment minister, will be promoted to the new title of Minister for Jobs and Innovation.
She will also surrender her title as Minister for Women, which will be taken by Kelly O’Dwyer.
Bridget McKenzie, who recently replaced Fiona Nash as the deputy leader of the Nationals, has also entered the parliament. She will be the new Minister for Sport, Rural Health and Regional Communications.
Dan Tehan has also been promoted to the cabinet, taking over Mr Porter's previous position as Minister for Social Services.
