London: Steve Smith and David Warner hit fifties as Australia compile 287-3 on day one of the final Ashes Test against England at The Oval on Thursday.
Steven Smith was 78 not out and Adam Voges was 47 not out.
Michael Clarke was out for just 15 in his last match before his international retirement.
Clarke, one of the best batsmen of his generation but in the middle of a prolonged dip in form, fell when he was caught behind by wicket-keeper Jos Buttler off a rising delivery from pace bowling all-rounder Ben Stokes that cut away off the seam.
Kumar Dharmasena gave Clarke out but, after consulting vice-captain and non-striker Steven Smith, the batsman reviewed the Sri Lankan umpire's decision.
But Indian replay official S Ravi upheld Dharmasena's decision after technology indicated a thin nick and Australia were 186 for three.
Clarke faced 29 balls in 42 minutes Thursday, driving off-spinner Moeen Ali down the ground for the only four of his innings.
Rogers, also playing his last Test before calling time on his Australia career, and fellow left-handed opener Warner put on 110 after Cook won the toss on a green-tinged pitch and under overcast skies.
The conditions were reminiscent of the first morning of the fourth Test at Nottingham's Trent Bridge, where Australia were bowled out for just 60 in 111 balls -- the shortest completed first innings in Test history -- a fortnight ago.
England went on to win that match by an innings and 78 runs, a victory that saw them regain the Ashes and take an unbeatable 3-1 lead in the five-match series.
But Rogers, one of the few Australia batsmen who had been willing to 'knuckle down' this series, and Warner were far more watchful on Thursday.
Meanwhile Stuart Broad, who took a sensational eight for 15 in Australia's first innings at Trent Bridge, was fractionally too wide against batsmen determined not to 'chase' the ball after their Nottingham nightmare.
The first hour's play saw Australia 19 without loss in 14 overs, compared to 38 for seven in 11 in 60 minutes at Trent Bridge.
Australia's first boundary did not arrive until the 15th over when the normally aggressive Warner -- who had faced 45 balls without a four -- pulled Ben Stokes through square leg.
An increasingly assured Warner, gaining from time in the middle, went to a 76-ball fifty when he cover-drove fast bowler Steven Finn for his seventh four.
At lunch, Australia were 82 without loss, with Rogers 43 not out and Warner 53 not out.
England hold an unassailable 3-1 lead after winning the past two Tests.
