Steve Smith scored his maiden Test century to help Australia to 492-9 declared as England toiled on a rain-affected day two of the fifth Ashes Test at The Oval.
Smith was left unbeaten on 138 after he became the second Australia batsman to reach three figures with Shane Watson having compiled an inspired 176 on day one.
England had to negotiate a tricky 17.3-over period in an extended evening session after rain washed out the morning's play, and captain Alastair Cook (17) and Joe Root (13) came through it unscathed to lead the hosts to stumps without loss.
But it was Australia's day and Smith's, in particular, as England's bowlers were left frustrated with only James Anderson - who finished with figures of 4-95 - able to cause damage as the tourists racked up a commanding first-innings total.
England's two debutants, who struggled so badly on day one, were given little or any chance to respond as Simon Kerrigan was not given a single over in the day, while Chris Woakes was at least able to grab his first Test wicket late in the Australia innings.
The day belonged to Smith, who lofted a delivery from Jonathan Trott over the bowler’s head for six to bring up his three figures as Australia, seeking a consolation victory in a series they trail 3-0, turned the screw on their weary hosts.
Australia resumed on 307 for four when play started three and a half hours late due to rain, and England paceman Anderson soon bowled nightwatchman Peter Siddle for 23 with a jaffa of a delivery.
But Smith and Brad Haddin shared an untroubled sixth-wicket partnership of 65 as the England fast bowlers failed to take full advantage of overcast conditions on what remains a flat wicket at The Oval.
Smith, who was 66 not out overnight, continued to hit boundaries at regular intervals and England captain Cook was forced to turn to part-time medium-pacer Trott ahead of Kerrigan, whose confidence appeared to be left shattered after eight overs for 53 on day one.
Smith launched Trott over long-on with a crisp strike to get to his first century in his 12th Test, in an innings which spanned five hours and included two sixes and 16 fours.
Trott did force Haddin, on 30, to chop the ball on to his stumps but Smith was joined by James Faulkner, making his Test debut, and the pair took the touring side safely through to tea.
Faulkner was superbly caught by Trott after the interval as Woakes claimed his first Test wicket, before Mitchell Starc (13) and Ryan Harris (33) ended the tourists’ innings with a late flourish before Clarke brought it to an abrupt end.
Australia’s bowlers were unable to make a late breakthrough as the light faded in an extended evening session, but Clarke’s side were delighted with their progress as they look for early wickets on day three in their bid to salvage something from a series England have already won.
