The final free practice session before Australian Grand Prix qualifying was a mixed affair with rain interrupting proceedings 16 minutes into the hour.
The session began in strong sunshine, but with heavy clouds gathering around Albert Park, drivers headed out as soon as the pitlane light turned green, Mark Webber being the first driver to set a time. That was soon eclipsed and times continued to fall until the rains came. At that point Romain Grosjean was quickest with a time of 1m26.929. Behind him were the Ferraris of Fernando Alonso and Felipe Massa.
