Sebastian Vettel set the fastest lap ever at the Albert Park circuit in the last practice session before qualifying for the Australian Grand Prix on Saturday, finishing almost a half-second clear of Mercedes teammates Valterri Bottas and Lewis Hamilton.
Vettel drove his Ferrari around the 5.303-kilometre (3.295-mile) Melbourne track in 1:23.380 seconds.
Bottas, in his first race since replacing retired world champion Nico Rosberg at Mercedes, was second quickest in 1:23.859 and three-time world champion Hamilton was third in 1:23.870.
Vettel's Ferrari teammate Kimi Raikkonen was fractionally under 1:24 to post the fourth-quickest time - and was the only other driver to go under 1:25, despite stopping when he punctured his left rear tire early in the session.
Hamilton had the fastest times in the first two practice sessions of the Formula One season on Friday.
