Marnus Labuschagne denied Australia has let its intensity levels slip after retaining the Ashes despite England dominating day two of the final Test.
After Rory Burns saw a poor lbw verdict from umpire Kumar Dharmasena overturned on review from the final ball of Friday's play at The Oval, England lead by 78 runs with all 10 wickets in hand in its second innings.
Labuschagne made 48 but was one of six wickets to fall to England paceman Jofra Archer as Australia was bowled out for 225, Steve Smith offering the main resistance with a typically doughty 80.
England is well placed to close out a victory that would draw it level at 2-2 despite failing to reclaim the urn, but Labuschagne insists Australia remains determined to win the series.
"We came here today looking for a really solid batting performance and obviously we didn't do that but we're still in the contest," Labuschagne told BBC Sport.
"The intensity definitely has not dropped. It's hard to say that when our play on the field maybe reflects that. But we came to win the Ashes and we really want to do that.
"We don't want to just retain the Ashes. We have to come out tomorrow 100 per cent on it and ready to take any chance."
