Casey Stoner was fastest on a cold Saturday morning at Phillip Island. The Australian was fast from the start, ceding the top spot only briefly to Dani Pedrosa, before forcing the Repsol Honda man back into 2nd spot. But Stoner's margin was small indeed, less than five hundredths of a second over Pedrosa. Valentino Rossi was 3rd fastest, over quarter of a second off Stoner, while Jorge Lorenzo improved his standing, but still eight tenths slower than the Ducati of Stoner.
The session was brief, however, as the weather turned and the rain chased everyone into the pits just after the halfway mark. With less than 5 minutes to go, the riders took to the track once again, but the wet track meant that times were 10 seconds or more slower than the best times set previously, and nobody improved their time.
