Melbourne - Jenson Button says there is more to come from his Brawn GP Formula One team in 2009 after the British driver and team-mate Rubens Barrichello finished first and second in Sunday's season-opening Australian Grand Prix in Melbourne.

Button led from start to finish at the Albert Park circuit as Brawn GP become the first debut team to finish one-two since 1954, when Juan Manuel Fangio led home Karl Kling for Mercedes in the French Grand Prix.

However, the 29-year-old said the victory was more difficult than it looked and he was now looking forward to this weekend's race in Sepang.

"It wasn't the perfect race and there's room for improvement, but we got the win and hopefully this is the first of many. I can't wait for Malaysia now," Button told the BBC.

"We can definitely improve our restarts and I really struggled to get temperature into the tyres as well. I also made a mistake in the first pit stop so there's more to come from both me and the team.

"I made it difficult for us today but we got there." (dpa)
