Organisers of the Australian Grand Prix have made changes to the Melbourne layout following Timo Glock's violent crash a year ago.

The German driver left Albert Park in 2008 wearing a bandage on his wrist, after his Toyota ran wide at the high speed turn-12 chicane and was spectacularly launched into the air over an uneven section of runoff.

A week ahead of next Sunday's event at Albert Park, F1's governing body confirmed that the ‘verge on the exit of turn-12 has been flattened’.

The kerbs and artificial grass have also been extended at the exit of the chicane, and a similar change has been made at turn 6, the FIA added.
