Spain's Carlos Checa (Ducati Althea Racing) scored a splendid double win at Phillip Island, a repeat of his double win at Imola last September.

Just like in the first race, no one was able to run with the Spanish rider and he finished a couple of seconds ahead of Max Biaggi (Aprilia Alitalia).

The reigning world champion battled it out for the runner-up slot in the final stages with an impressive Marco Melandri (Yamaha World Superbike Team), just getting the edge at the line.

Jonathan Rea (Castrol Honda) emerged from a battering and bruising weekend with a fourth place that partially repaid him for his testing misfortune when he crashed heavily.

Rea finished ahead of the two Leons, Haslam (BMW Motorrad) and Camier (Aprilia Alitalia).
