Why does Nadal win more Wimbledon than the Australian Open?

[skypadq]

nadal won wimbledon two time ( 08 , 10 )
and nadal won aus open one time ( 09 )
so one time diffrence

The Australian Open opened early in the season, so when you have the best physical strength
and grass is low bouncing and fast court surpace

so Why does Nadal win more Wimbledon than the Australian Open?
