Australia striker Josh Kennedy says he is unsure of his fate just days out from the World Cup opener against Germany.

The Nagoya Grampus man has led the frontline for the Socceroos in all of the warm-up matches but it is still uncertain if he will start on Sunday in Durban.

News that Harry Kewell is close to full fitness has buoyed the Australian team and given head coach Pim Verbeek another strike option as they prepare to take on the efficient Germans.

Kennedy admits that having Kewell back in calculations is great for the team but also says that it has made him vulnerable.

"It depends on how the boss wants to play," said Kennedy.

"I'm a different player to Harry. Harry is fit now and I think that is a fantastic thing for everyone.

"We'll see what the boss has in store.

"All I can do is my best," he added. "All I can concentrate on is my job rather than what's outside my control.

"Harry has done the same."
