The German lapped the Albert Park circuit in one minute 29.375 seconds, well ahead of McClaren's Jenson Button by 1.391 seconds on a warm day in Melbourne.

Two-time world champion Fernando Alonso was third fastest, with Lewis Hamilton, who topped the second free practice on Friday, fourth in his Mercedes.

"Horrible. The car doesn't accelerate," the Red Bull driver barked over the team radio.
