Australian golfer Robert Allenby has recounted how he was kidnapped, beaten and robbed in Hawaii, admitting he didn't expect to survive.

The 43-year old, who has since been pictured beaten and bloody, said he was abducted on Friday night at a popular bar in Waikiki, Honolulu.

He said he was likely drugged before being taken to an underground parking lot where he was beaten unconscious, robbed and thrown in a car boot.

Allenby told the AAP news agency how he was helped by a homeless woman and a retired military man after being dumped in a park, groggy and without his belongings.

The incident is reportedly being investigated as second-degree robbery.

"I didn't think I was going to survive this one," Allenby told AAP.

"I was separated from my friends in the bar after we had paid the tab at 10:48pm and he went to the bathroom and next thing you know I'm being dumped in a park miles away.

"I only know this part because a homeless woman found me and told me she saw a few guys pull up and throw me out of the car. That is where I got the scrapes above my eye from the sidewalk."

This woman guided him away from a group of other homeless people in the park that were starting to harass him.

"The homeless woman got me away from the others and then a retired military guy walking past came to my aid," he said.

"He got me into a taxi and paid for me to get to my hotel and I called police from there. I have his details and will be getting back in touch with him for sure."

Allenby said he was worried he wouldn't be able to call his 13-year-old daughter Lilly on her birthday, but his injuries were found to be superficial and he is thought to be safe to travel.

"She's really upset about it, but at the end of the day it could have been a lot worse."

Allenby, ranked 271 in the world and winner of four titles on the PGA Tour, was due to fly out of Hawaii following his failure to make the cut for the Tour's Sony Open after the first two days of play.
