Valtteri Bottas will start the Australian Grand Prix from 16th place after receiving a gearbox penalty.
Bottas failed to maximise the potential of his Williams during Saturday's qualifying session and was knocked out in 11th place, five spots behind team-mate Felipe Massa. That result has now been compounded by the need for a gearbox change, which demotes Bottas another five places.
It has been a bad 24 hours for Williams as the team has also been handed a reprimand for failing to "submit complete suspension set-up sheets for car 77 [Bottas] before the car left the pit lane for the first time in qualifying".
Williams was only reprimanded as: "The team made reasonable efforts to provide the sheet but due to a change in team document format failed to provide all required information by the deadline."
