Jenson Button won the first Grand Prix of the season in a one-two for Brawn GP, but does the result in Melbourne signal a new era for Forumla One?

The old Honda team, lead by Ross Brawn, dominated the Australian Grand Prix, with Button leading from start to finish and Rubens Barrichello grabbing second.

With their performance in Melbourne, will Brawn GP dominate the 2009 F1 season and is Button nailed-on to be world champion?

Jano Trulli and Timo Glock went well in their Toyotas, while the Red Bulls and Williams cars also looked powerful in Melbourne.

The traditional powerhouses of Ferrari and McLaren struggled, although Lewis Hamilton did managed to get third place after struggling in qualifying, but have the big two been knocked off their perch this year?

Has defending champion Hamilton got any chance of retaining his title with the McLaren car struggling, will Ferrari challenge this season, or are the new challengers here to stay?
