Countdown Music Aust: Alonso looking quick in these conditions. Would have gone quickest of all on his last lap but pitted. It's just FP3 on inters but looks promising.

Former Renault driverI'm sure it will dry up more this afternoon and we are still expecting to get a dry qualifying but it is still worth getting out there and learning as much as you can.

Bits of blue sky peeking through the clouds now. It's looking increasingly likely that we're going to get a dry qualifying session but then this is Melbourne, I've seen it rain there when there's barely been a cloud in the sky. Not quite sure how that works.
