World champion Jenson Button is looking to build on his Australian Grand Prix victory in Melbourne and enjoy more success with McLaren this season.
The 30-year-old started fourth on the grid at Albert Park behind Ferrari's Fernando Alonso and the Red Bulls of Mark Webber and Sebastian Vettel.
Button had expressed concerns in the build up to the weekend that McLaren were not yet capable of challenging the pace of their rivals.
However, the Briton made an inspired choice to switch to slick tyres early on a damp circuit and climbed up to second before taking the lead for good after the luckless Vettel retired with a mechanical problem. Button also won in Australia last year on his way to the world title with former team Brawn GP and is hoping Sunday's victory can provide a springboard for further success with McLaren.
“It is a very special feeling and we will take a lot from this,” he said. “I feel I am just building in confidence and hopefully, when we get to the next race, we can do something similar as this feels too good. It is always a team effort and I need to thank the McLaren Mercedes team for all their hard work and it is good to see we are improving every step of the way.”
The thrilling race was just the tonic Formula One needed following criticism of the opening race in Bahrain two weeks ago.
