Casey Stoner has won his sixth successive Australian Motorcycle Grand Prix and Spaniard Jorge Lorenzo the MotoGP world championship.
Lorenzo finished second to Australia's Stoner at Phillip Island to secure the overall title, with Briton Cal Crutchlow third.
The only other man who could win the world championship - Honda rider Dani Pedrosa - crashed out of Sunday's race on lap two, while leading.
