Melbourne: Michael Clarke will captain Australia for the first time and Usman Khawaja will make an historic debut in next week's final Ashes Test in the absence of injured skipper Ricky Ponting.
Clarke was promoted on Thursday from vice-captain to lead the team after Ponting was ruled out with a fractured little finger.
Wicketkeeper Brad Haddin was named vice-captain under Clarke for the Sydney Test, which gets underway on Monday.
Pakistan-born Khawaja will become the first Muslim to play Test cricket for Australia as Ponting's batting replacement as the home side seeks to level the series.
Khawaja, 24, who has scored the most runs (598) in the domestic Sheffield Shield competition this season at 74.75, will be considered for the demanding number three spot, the position occupied by Ponting.
"Usman will make his debut for Australia in this match, something we are excited about given his tremendous form at domestic level over the past two seasons," Hilditch said.
Paceman Doug Bollinger, dropped after the second Test in Adelaide, is back in Australia's 12-man squad after Ryan Harris suffered a stress ankle fracture in the Melbourne Test.
Australia squad Michael Clarke (capt), Brad Haddin (vice-capt), Shane Watson, Phillip Hughes, Usman Khawaja, Mike Hussey, Steve Smith, Mitchell Johnson, Peter Siddle, Ben Hilfenhaus, Doug Bollinger, Michael Beer.
