Circuit used for the Australian Grand Prix, the prediction was that lap times would be around the 1:15 to 1:20 mark; however, qualifying times were around 15 seconds slower than this. Ken Tyrrell was the only team boss who refused to sign the document which would have allowed the race length to be reduced. In the race, Jonathan Palmer lost a certain 4th place when his Tyrrell 018 ran out of fuel on lap 69. Had the race been flagged after 70 laps, Palmer would have finished 4th having already been lapped by Prost instead of running out of fuel and being classified as 9th and last. The organizers were slightly disappointed with a crowd of 31,441 turning out for the race on Sunday in 100 degrees Fahrenheit heat, having hoped for 40,000.
