| Welcome to ESPN Racing-Live.com and live coverage of the second practice session of the Australian Grand Prix weekend. |
| 16:22:20
| Earlier this afternoon we saw Williams Toyota top the timesheets with Nico Rosberg recording a best lap of 1:26.687s. Team-mate Kazuki Nakajima also impressed with the second fastest time, just five hundredths of a second adrift. |
| 16:24:13
| Kimi Raikkonen was third fastest but was the only front-runner to use a set of super-soft Bridgestone Potenza tyres and therefore his time in the new F60 is not particularly representative. |
| 16:26:12
| As expected, Brawn Mercedes were strong underlining their pre-season testing pace. Rubens Barrichello was fourth best and Jenson Button sixth. |
| 16:28:20
| Heikki Kovalainen split the Brawn duo in his McLaren Mercedes while team-mate Lewis Hamilton struggled to 16th. It was a tough session for Red Bull Renault with Vettel suffering a hydraulic failure and Mark Webber a drive-shaft issue. |
| 16:30:06
| The second 90 minute practice session is now underway. |
| 16:30:38
| Jarno Trulli is the first man on track. He was 12th fastest this morning. |
| 16:31:15
| Glock, Alonso, Bourdais, Webber, Vettel, Rosberg head out. |
| 16:32:10
| Others now on track as well. The sun has come out and that should help the grip levels. |
| 16:33:46
| Trulli completed the first lap of the session, a 1:31.5 |
| 16:34:11
| Correction, that time was Glock who sets the pace from Trulli. |
| 16:34:38
| Now Webber moves fastest as others post first laps of the session. |
| 16:36:09
| All change as Adrian Sutil moves P1 ahead of Glock, Fisichella and Alonso. |
| 16:37:23
| They're all running the harder tyre at the moment. At the end of the session may will opt to run the super-soft. |
| 16:37:49
| Sutil runs wide as Alonso goes for a spin. |
| 16:38:17
| Williams are back on top with Nico Rosberg now fastest from Nakajima and Kovalainen. |
| 16:39:31
| The times continue to come down as Sutil re-takes the fastest time from Nakajima, Fisichella and Rosberg. |
| 16:40:43
| Sutil pits his Force India Mercedes. |
| 16:42:03
| Webber moves third fastest behind Kovalainen and Sutil. |
| 16:42:47
| Hamilton and Massa run nose to tail on track. |
| 16:43:07
| Glock moves third fastest. |
| 16:43:40
| Hamilton, ninth, locks his front left wheel and continues. |
| 16:44:18

| 16:44:31
| Hamilton moves third fastest. |
| 16:45:32
| Button vaults fastest for Brawn Mercedes. |
| 16:47:13
| Another gain for Button next time around but still 1.2s off the earlier best time recorded by Rosberg. |
| 16:47:44
| Trulli is back out and is on the softer tyre. |
| 16:48:47
| Trulli gains some 2.2 seconds on his previous best and moves fastest on a 1:27.2. |
| 16:49:53
| Trulli remains fastest from Button, Hamilton and Sutil. |
| 16:51:51
| Kubica, 19th, is back on track. He is not running KERS this weekend whereas team-mate Heidfeld is. |
| 16:52:40
| Fisichella is back out and he is on the soft tyre. |
| 16:53:01
| Trulli pits after a long stint on the soft tyre. |
| 16:53:28
| Sutil moves second fastest, with Fisichella up to third. |
| 16:55:29

| 16:56:07

| 16:56:23
| Vettel moves third fastest in his Red Bull. |
| 16:57:39

| 16:58:09

| Trulli moves second fastest in his Toyota. |
| 17:03:48

| 17:06:32
| Barrichello picks up another position and is now third. |
| 17:06:55
| Rosberg heads back out. |
| 17:08:07
| Piquet and Alonso are on track for Renault looking to make up time. |
| 17:08:43
| Rosberg is out on the soft tyre, so should be able to improve on his own best. |
| 17:10:09
| Rosberg does make a slight gain and is now three-tenths ahead of Trulli. |
| 17:10:46
| Massa has to take avoiding action as someone slows in front of his at turn one. |
| 17:11:09
| Heidfeld remains slowest and is in the BMW Sauber pit. |
| 17:13:59
| Nakajima picks up seven positions and is now sixth fastest in the second FW31. |
| 17:15:19
| Hamilton remains on track but is not making progress up the timesheets at the moment. |
| 17:15:53
| Rosberg has to swerve to avoid a slowing Red Bull. |
| 17:16:19
| The Williams driver returns to the pits. |
| 17:16:54
| Kubica is 12th and back in the pits complaining of a general lack of grip. |
| 17:17:56
| Glock runs wide and continues. |
| 17:19:10
| Webber moves seventh fastest. |
| 17:20:52
| Another gain from Webber who is fourth fastest. |
| 17:22:25
| Trulli, second fastest, runs wide at the first turn. |
| 17:23:10
| Piquet, 19th, is out on the soft tyres. |
| 17:23:45
| Kubica remains 12th on the soft tyre. BMW Sauber not showing well at the moment. |
| 17:24:44
| Kovalainen is on the soft tyre. |
| 17:26:14
| The times are stable at the moment. Most will be on fairly worn rubber by this stage of the Friday running. |
| 17:26:59
| Alonso is 20th behind Raikkonen. That is a surprise. |
| 17:27:12
| A gain for Alonso as he moves P12. |
| 17:28:37
| Track temperature is falling despite the sunshine as Vettel spins his Red Bull. |
| 17:29:59
| He's stalled the RB5 on the grass at turn 3 and is now out of the car. |
| 17:30:39
| Vettel was eighth fastest but will now miss the final 30 minutes of running. |
| 17:30:54
| The Red Bull is now being craned away. |
| 17:31:36
| Raikkonen is now slowest but he is back out as is team-mate Massa. |
| 17:32:50
| Sutil passes Raikkonen after the Finn locked his brakes. |
| 17:34:53
| Massa does not improve on his tenth position on that lap. |
| 17:37:53
| Rosberg remains on top for Williams from Trulli, Barrichello, Webber, Button, Glock and Nakajima. |
| 17:40:06
| Raikkonen remains on track and slowest of all. He must be on a heavy fuel load at the moment as he is some way off the pace. |
| 17:40:46
| Rosberg backs off to get some track space and starts another fast lap. |
| 17:43:50
| No one is improving at the moment. It is late afternoon now in Melbourne and the track temperature is falling away. |
| 17:45:48
| Hamilton pits the McLaren complaining that the car is running too low and bottoming out. |
| 17:46:14
| Massa is back out on the soft tyre. |
| 17:47:14
| Massa has a half spin late in the lap and did a great job not to spin the Ferrari. |
| 17:47:28
| Massa now runs off track at the first turn. |
| 17:48:50
| Raikkonen moves 14th demoting Buemi to the bottom of the timesheets. |
| 17:49:23
| Now Raikkonen runs off at turn one. The soft tyres seem to give up grip very quickly. |
| 17:51:02
| Barrichello, third fastest, heads out in his Brawn Mercedes. |
| 17:51:59
| Raikkonen improves again and is now 11th. |
| 17:54:30
| Heidfeld locks the rears and runs wide. |
| 17:54:59
| Button baulks Nakajima. |
| 17:55:59
| As expected, McLaren are struggling with Kovalainen and Hamilton 17th and 18th. |
| 17:56:25
| All on track except Webber and Vettel. |
| 17:58:41
| Barrichello picks up a couple of tenths and is now second fastest for Brawn Mercedes. |
| 17:59:32
| Fastest three cars are Williams, Brawn and Toyota... No wonder some rivals are unhappy. |
| 18:00:10
| The chequered flag is out. |
| 18:00:41
| So Roberg tops the timesheets for the second straight session in the Williams Toyota. |
| 18:01:26
| Rosberg is fastest from Barrichello, Trulli, Webber, Button, Glock, Nakajima, Vettel, Sutil and Massa. |
