Former Australian tennis star opens up over coach abuse

A former Australian tennis star has described being spat at, beaten and kicked by her father and coach over years of abuse during her professional career.

Jelena Dokic was once world number four, but never lived up to her massive potential.

"I really played out of fear and I was scaredm" she says. "There was a lot of pressure - I was constantly trying to please him and I think that's why I was so good, especially early on."

Damir Dokic was both her father and coach, a menacing presence on and off court.

He was once kicked out of the US Open and eventually banned from tour events.

But it was his outbursts behind the scenes that built and then broke his daughter's career.

"I was never hit or abused by my father, until that very first day when I started playing tennis," she says.

Dokic has released a new book, Unbreakable, which tells the full story of the abuse that grew with success.

It tells of how he would beat her and lash her with whips, whenever he felt her performance was lacking.

After she lost a Wimbledon semifinal, which she reached at the age of just 17, Damir locked her out of her London hotel and forced her to sleep outside on a couch.

And after a different first-round defeat, he beat her so hard, she was knocked unconscious.

Jelena eventually broke away from her father, who went to jail for explosive threats, but by then, the damage was done.

"In the end, he kind of ruined my career and, in a way, really shortened it," she says.

"Whether I would have been number one and won a Grand Slam, I don't know... maybe, but if not, I would have been a very consistent top-five or top-10 player."

The former world number four is today retired, but Jelena Dokic has one thing left to win.

She wants to raise awareness of the damage of domestic violence, so that others don't suffer like her, for success.
