01:15 Hello everyone and welcome to AUTOSPORT Live for this, the second round of the 2010 FIA Formula One World Championship.

The teams and drivers are already clocking up the air miles as the flyaway events continue. Two weeks ago the campaign opened up in Bahrain but the race proved to be an anti-climax for many.

Now we move on to the wonderful Albert Park in Melbourne for the Qantas Australian Grand Prix, with everyone hoping for a better show this time around.

01:16 Today, we will guide you through the opening practice sessions with minute-by-minute commentary as the teams and drivers get their first runs on the 5.303 km parkland circuit.

First practice will begin shortly, with commentary ending 15 minutes after the session has concluded.

Later, at 05:15 GMT, we will return for live coverage of the second practice session. AUTOSPORT Live will wrap up the day with a weekend weather forecast, on the Australian Grand Prix weather page.

01:18 Ferrari is the team to beat going into the weekend, but it might have been different had Sebastian Vettel not suffered a spark plug failure while leading comfortably in Bahrain.

The Red Bull star dropped down fourth with the resultant loss of power from his Renault engine, handing the race on a plate to Fernando Alonso and Felipe Massa.

Lewis Hamilton finished a fighting third and will be looking to build on his tally, while Mercedes will hope to find a bit more pace so that Schumacher and Rosberg can fight for victory.

The rest of the teams have work to do to stop the top four teams escaping into a battle of their own, and at the back of the field we can expect more fun and games as Lotus, Virgin and HRT look to build speed and hopefully enjoy some trouble-free track time.

01:20 The weather has been fine this morning over the circuit and we start today's action with a dry track, plenty of sunshine and just a few clouds around.

As the day continues, more cloud will build from the west and there is a slight risk of showers towards the end of second practice. Light showers are expected later tonight, so hopefully today's running will be unaffected.

There will be a north-westerly breeze during practice, switching round to a south-westerly by the end of today. The top temperature should reach 28 degrees Celsius.

01:21 AUTOSPORT forum members are invited to join the fun throughout the weekend, offering thoughts and opinions as the event unfolds.

Our questions to you for today are:

• Who will hit the ground running first this weekend at Albert Park? In Bahrain, McLaren looked good initially before Ferrari and Red Bull came on strong.

• Will Sauber's new F-duct system help push Pedro de la Rosa and Kamui Kobayashi into the top ten this weekend?

• Michael Schumacher used to own this place. He has four victories at Albert Park to his name - 2000, 2001, 2002 and 2004. How will he fare this weekend?

Tell everyone what you think.

01:23 Some news in brief ahead of the first session:

• Force India tester Paul di Resta gets his first race weekend outing this morning when he takes over Adrian Sutil's car for the first free practice session. "Hopefully, this year we are going to gain a lot of experience and hopefully I can show the team that I am capable of being in a race car at some point in the near future," he explained.

• Changes to circuit since last year include a new combination kerb at the exit of Turn 9 while the kerbs and grass have been extended at Turns 2 and 12.

• Bruno Senna will use a new Cosworth engine in his HRT this weekend following his retirement from the Bahrain Grand Prix with overheating. Team-mate Karun Chandhok hopes that improved gearbox hydraulic systems will allow him more track time than his heavily-disrupted Bahrain debut.

• This is only the second time that Melbourne has not hosted the opening round of the season since its inception in 1996. 2006 was the other year when the event was moved due to a clash with the Commonwealth Games.

59 min: Kobayashi had just left the pits in the Sauber for another run of laps. Coming down to Turn 3 his front wing came off as he started braking for the tight right-hander.

60 min: The front wing then shattered to pieces, hitting one of the polystyrene braking marker boards. The wing had just been changed following his earlier incident at Turn 11 causing the first red flag.

68 min: Bruno Senna improves from 24th position to 23rd with a time of 1m35.964s. He is now 8.4s off the leading pace, set by Button.

71 min: Kobayashi is watching the action from the Sauber garage as his team try to get to the bottom of that worrying wing failure.

75 min: Karun Chandhok gets his braking all wrong for Turn 3 in the HRT. He does well to keep it together and just stay on the track. The India is now 23rd in the standings, three-tenths of a second behind team-mate Senna.

76 min: Kubica is on another quick tour and is fastest through the first and second sector.

76 min: Sebastien Buemi improves for the second lap on the trot and goes sixth in the Toro Rosso with 1m28.294s.

76 min: Despite traffic in the form of Chandhok's HRT, Kubica is back on top in 1m26.927s.

76 min: Chandhok has recovered from his late-braking Turn 3 moment well enough to post 1m34.345s on his next lap. He improves to 22nd place.

78 min: Pedro de la Rosa has pulled to a halt out of Turn 4.

79 min: Yellow flags are being shown as de la Rosa is wheeled back behind the wall.

84 min: Massa continues to improve in the Ferrari with a 1m27.868s.

84 min: Karun Chandhok reports on the team radio that the circuit is picking up grip all the time. He is feeling more and more happy with the improvement in speed on each run.

85 min: Most of the drivers are on track to put some final laps on the set of tyres they must hand back after this session.

85 min: Bruno Senna runs wide as he attacks Turn 15. He sails onto the grass but does no damage to the HRT. He has stayed out to continue the run.

88 min: Alonso is working hard at the wheel of his Ferrari and is now seventh quickest with a 1m27.919s.

88 min: Timo Glock is propping up the order in this session with his Virgin machine undergoing repairs in the garage after only eight laps today.

89 min: Paul di Resta is 14th in the Force India. He was on for an improvement on his latest tour but backed off towards the end so he could get some clear space for a final effort.

90 min: The session has ended. Cars that have already started a lap may complete it.

03:01 Karun Chandhok found one tenth of a second on his way to 1m34.251s on his final effort. He ends the session in 23rd position.

03:01 A late 1m28.114s puts Petrov ninth in his Renault.

03:08 Here is our round-up of a busy first session at Albert Park:

Kubica fastest in first Melbourne practice

03:11 Australia has certainly delivered excitement as the cars took to the track for the first session.

Kamui Kobayashi made the session his own with two unfortunate incidents in the Sauber, while Michael Schumacher raised many an eyebrow when he kept his foot in under red flag conditions.

Robert Kubica put Renault on top, but can he stay there? Join us for live coverage of the second practice from 05:15 GMT.
