Lewis Hamilton was the fastest driver in the opening practice sessions at the first Grand Prix of the new Formula 1 season in Australia.
The reigning world champion finished 0.048 seconds ahead of his Mercedes teammate Valtteri Bottas in the second run.
The Red Bulls of Max Verstappen and Pierre Gasly were a further 0.8 seconds adrift while Ferrari's Sebastian Vettel was fifth-fastest.
