McLaren's Lewis Hamilton starts from the front row at the season-opening Australian Grand Prix at Albert Park in Melbourne.

Vettel's lead down to 1.2s and comes into the pits. Can Lewis emerge ahead of him after he's been in?

Webber has been in and come back out in ninth and now, a couple of laps later, Massa also does so. Would have to be a drivethrough penalty.

Button tells his team he had track position so does not feel it was his fault. Race director Charlie Whiting and his stewards are officially investigating the incident now.

And Alonso sneaks up the inside of his team-mate. Will the McLaren driver be penalised by race stewards? He got caught out at turn 11 and cut the corner.

Button past Massa but gained an unfair advantage - and Alonso is also there! How will he let one Ferrari through and not the other? The answer is he won't - for now!

Pastor Maldonado's Williams comes to a stop at turn nine and will retire.

The drivers who made it to Q3 are on the tyres they used there so their lifespan is coming to an end - the teams preparing to bring them in.

Button increasingly frustrated and is now coming under pressure from the other Ferrari of Alonso. Massa closing the door repeatedly.

Buemi passes Briton Di Resta, who had a superb start to move up to 10th at the race start. He is 11th now.

Button complaining over the radio about the tyres on the straight. His use of DRS still not seeing him past Massa.

Vettel's lead stabilised at just over three seconds. The first pitstops could be as early as lap 10.

The order: 1.Vettel 2.Hamilton 3.Webber 4.Petrov 5.Massa 6.Button 7.Alonso 8.Rosberg 9.Kobayashi 10.Di Resta 11.Buemi 12.Sutil 13.Heidfeld 14.Perez 15.Barrichello 16.Kovalainen 17.Maldonado 18.Trulli 19.D'Ambrosio 20.Glock 21.Alguersuari 22.Schumacher

Vettel leads by 3.1 seconds but is not building on that as Hamilton sets the fastest lap with 1:32.582. Schumacher had a puncture and is way back in last position.

Rubens Barrichello's Williams shot off at the first corner as he looked to make up grid position from 17th.

Button opens the Drag Reduction System on the main straight but is fended off by the Ferrari again.

Webber all over Hamilton while Button is challenging Massa. Both drivers successfully defending for now.

Alguersuari has to come in after a lap with damage.

Positions seven to 10: Nico Rosberg, Kamui Kobayashi, Fernando Alonso - down four spots in the Ferrari - and Jaime Alguersuari.

Webber stays third but Button is down to sixth with Renault's Vitaly Petrov up to fourth from sixth and Felipe Massa making up three spaces for fifth!

Blazing start from Vettel! He builds an immediate gap with Hamilton recovering after a slow one to retain second.

WE ARE GO GO GO DOWN UNDER!!!!
