Australia Friday quotes: Brawn GP

Jenson Button - 5th: "It was great to finally get the season underway today. We had a good first day of practice and the long run performance looks competitive, particularly on the harder tyre. We still have some work to do on the softer tyre so that will be a priority for tomorrow's practice session. I had traffic on both of my new tyres runs at the end of the day which was a shame so we don't know how quick we are over one lap yet but there is plenty of time to find that out tomorrow."

Ross Brawn: "The circuit at Albert Park is very different to the tracks that we used for our limited pre-season testing programme so our focus today has been on setting the car up to suit the conditions that we have here and the preferences of our drivers.

"Track conditions improved considerably in the second session however we are clearly not alone in finding the experience of running slightly later in the day less favourable than anticipated. It is a useful indication of what we may find when the race runs at a similar time on Sunday. The car performed well and we are pleased with the day's work experiencing only minor issues which are to be expected with our limited testing mileage. A good start to the weekend."
