Ferrari's Sebastian Vettel has beaten pre-race favourite Lewis Hamilton to victory in the season-opening Australian Grand Prix.
The German claimed his first win since the Singapore GP in September 2015 thanks to quick thinking from his team and a rapid pitstop, helping him beat Hamilton to first place in Melbourne.
Vettel had qualified second behind the Englishman, on his 62nd career pole position, and was beaten into turn one as the Mercedes got away cleanly, but the 32-year-old was unable to look after his tyres and was forced to make his pit stop on lap 17.
It was the first time that Ferrari won the opening race of the season since Fernando Alonso did so in Bahrain in 2010, and also Vettel's first victory at the opening race since 2011.
Hamilton had to settle for second, crossing the line almost 10 seconds behind Vettel, while his new Mercedes teammate Valtteri Bottas was third.
With Kimi Raikkonen finishing a distant fourth, Ferrari ended the first race of 2017 holding the lead in the constructors' championship for the first time in Formula 1's evolving hybrid era.
Elsewhere, Max Verstappen salvaged fifth on a troubled weekend for Red Bull, Felipe Massa took sixth despite trailing Vettel by almost a minute and a half, while both Force Indias and Toro Rossos secured points-scoring results despite being lapped.
Meanwhile Alonso, Kevin Magnussen, Lance Stroll, Daniel Ricciardo, Marcus Ericsson, Jolyon Palmer and Romain Grosjean all retired.
