Australia captain Tim Paine won the toss and opted to bowl first in the second Ashes Test at Lord's.
Paine called right under blue skies in London, where the opening day was washed out due to rain.
England captain Joe Root revealed he would also have bowled first if the coin had come down on the other side.
Paceman Jofra Archer and spinner Jack Leach replaced James Anderson (calf) and the dropped Moeen Ali in the England side following a defeat in the first match of the series at Edgbaston.
The tourists made just the one change to a winning side, with Josh Hazlewood getting the nod in place of James Pattinson.
Lord's is set to turn red on Thursday in aid of the Ruth Strauss Foundation, honouring former England captain Andrew Strauss' late wife.
