Ferrari's Charles Leclerc headed the McLarens of Oscar Piastri and Lando Norris in Friday practice at the Australian Grand Prix with Lewis Hamilton in fifth place.
Leclerc was 0.124 seconds quicker than Piastri, who edged Norris by 0.017secs. Hamilton was 0.420secs behind his team-mate on his debut for Ferrari.
Yuki Tsunoda's Racing Bull was the midfield interloper in the top order in fourth, and his rookie team-mate Isack Hadjar was in sixth, also ahead of Max Verstappen in the senior Red Bull team.
The world champion looked to be struggling. His best time was set on the medium tyre - he aborted his soft-tyre qualifying simulation run when he took three bites trying to turn into Turn Three and ran wide on the exit.
