David Warner set up the innings with a chance-filled 94 and Travis Head took over with an unbeaten century after a mini-collapse in the middle order to guide Australia to 343-7 at stumps on Day 2, a 196-run lead in the Ashes series opener.
Warner had a big reprieve on 17 off a no-ball from Ben Stokes, one of the many times the England allrounder overstepped but one of the few he was called for. Warner was also dropped in the slips on 48 and narrowly avoided being run out as he scrambled back to his crease on 60. But he ran out of luck after sharing partnerships of 156 with Marnus Labuschagne (74) for the second wicket and 23 with Steve Smith (12) for the third, finally out just after the tea interval when Ollie Robinson took two wickets with consecutive deliveries.
