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.

Melbourne, Mar 29 : Britain's Jenson Button led home a sensational one-two finish for Brawn GP in its debut Formula One team start at the Australian Grand Prix on Sunday.

Button rocketed away from the pole to lead throughout the 58 laps of the season-opener and kept clear of the mayhem behind him to cruise home in a safety car finish for his second victory in 154 GPs.

The 29-year-old was never headed in the 58-lap race, beating teammate Rubens Barrichello and Toyota's Jarno Trulli.

Reigning world champion Lewis Hamilton finished third in his McLaren.

Melbourne  - Toyota are to appeal the 25-second penalty imposed on driver Jarno Trulli after the Italian was deemed to have overtaken under safety car conditions during Sunday's season-opening Australian Grand Prix in Melbourne.

Trulli slid off the track in the safety car phase which forced Lewis Hamilton in a McLaren-Mercedes to pass him. Trulli then moved ahead of the world champion again, but the stewards deemed this move illegal under safety car conditions.

Melbourne  - The next round in the fight over aerodynamics among the Formula One teams is to take place after the Australian and Malaysian grands prix.
