Casey Stoner stays on top in final Australian Grand Prix practice

The Honda rider, who has an outside chance of wrapping up his second world title in front of his home crowd, hit the front with a little over half of the 45-minute session to go at Phillip Island in 1m31.279s and just kept getting faster.

While that initial pace-setting time, and subsequent others, were set on hard tyres, a switch to a softer front Bridgestone allowed him to improve his speed considerably in a session that proved slower than the previous day's due to high winds at the track.

He really picked up his pace with six minutes left and ended the session with a benchmark time of 1m30.550s.

While the Australian completed four successive laps inside the 1m30s, nobody else was able to dip below 1m31s. Stoner's only title rival Jorge Lorenzo, who led proceedings for much of the first half of the session, was second fastest, the world champion 0.640s down on his Yamaha.

Stoner's team-mate Dani Pedrosa was the only man to improve on his Friday pace in third, while Marco Simoncelli recovered from a crash at MG corner - his third such fall of the weekend - to put his Gresini Honda fourth.

Ben Spies was fifth for Yamaha with Andrea Dovizioso making it all three of the factory Hondas inside the top six.

Randy de Puniet, who had traded the top spot with Lorenzo early on, was an impressive seventh on his Pramac Ducati - the Frenchman well ahead of the works bikes of Nicky Hayden and Valentino Rossi in ninth and 12th.

Alvaro Bautista was eighth for Suzuki with Colin Edwards completing the top 10 on his Tech 3 Yamaha.

Damian Cudlin suffered a bizarre highside while tipping his Aspar Ducati into the Honda hairpin inside the opening few minutes of the session. He was taken to the medical centre to have a suspected hip injury checked out.
