Haga beat championship leader Troy Bayliss in the first race by 2.025 seconds, and he won the rain-curtailed second race on the countback rule.

Troy Corser led when the race stopped on lap 16 but the result was decided by placings in the final completed lap.

Haga's win was all the more impressive as he broke a collarbone two weeks ago.

His double win takes his championship points tally to 172, 55 behind leader Bayliss, who ended the weekend with a second and a fourth place finish after making mistakes in both legs.

Bayliss was leading the first race but he ran wide into turn one less than two laps from the end to hand victory to the Yamaha rider.

In race two Bayliss made two mistakes on the fifth lap, dropping from the lead down to fifth before recovering to fourth.

Suzuki rider Max Neukirchner, who impressed the home fans by taking superpole in qualifying on Saturday, continued to shine with a pair of third place finishes.
