Warner made 112 from 140 balls, his second century of the series, to take his tally for the campaign to 457 runs at 91.40, becoming the leading run-scorer in the series.
It was his fifth Test century and second in Perth, and in typical Warner fashion it included 17 boundaries and two sixes.
It is a remarkable effort from a player who was considered a marginal selection just a few months ago. He forced his way into the first Test side with a glut of runs at domestic level for New South Wales.
The dashing left-hander played only three Tests in the previous Ashes series in England, for 138 runs at an average of just 23. However, he is reaping the rewards of a much-improved fitness level, having shed a number of kilos from his diminutive frame.
His opening partner Chris Rogers said Warner was in the form of his life. “He makes me look a bit stupid at times,” Rogers said.
“It’s not that easy out there, so for him to be playing the way he is - I don’t think anyone can play as well as he is at the moment. It’s unbelievable.”
Rogers said Warner was blessed with attacking options few other batsmen possessed. “I think he just has an option for every ball, that’s an amazing skill to have.
“Batting down the other end, you know you’ve still got to wait for bad balls from the opposition, but he can make bad balls happen. To be able to hit the fast bowlers over their head for six, it’s an amazing ability.”
