Jelena Dokic says she's starting from zero as she continued her tennis comeback through the women's doubles at the Australian Open.

The former world No.4 fell short in her quest for a singles wildcard and turned out in the doubles with fellow Australian Storm Sanders.

They lost their round-one clash against Slovakian Magdalena Rybarikova and Swiss Stefanie Voegele 6-4, 6-4.

Dokic is trying to revive her career after two years out with injury and illness.

''I have the motivation to do it and, as long as that's there, I'm going to play,'' she said.
