Valtteri Bottas crushed the competition to win the Australian GP as Lewis Hamilton and Ferrari struggled at the F1 2019 season-opener.
Bottas, a distant third in the championship and without a victory last year, overtook Hamilton off the line and went on to win the race ahead of his pole-sitting team-mate by more than 20 seconds.
The Finn also took the maximum 26 points available after setting the fastest lap.
"It was definitely my best race ever," said Bottas.
Hamilton never seemed comfortable in his Mercedes, and only just held off a charging Max Verstappen in the Red Bull for second place.
Verstappen's impressive display in Red Bull's first race with Honda engines included a sensational overtake on Sebastian Vettel, with Ferrari finishing almost a minute behind race-winner Bottas.
