Australian golfer Robert Allenby says he has no recollection of being kidnapped, beaten and robbed in Honolulu.

Allenby was at the popular Amuse Wine Bar in the tourist-hub Waikiki with his close friend Anthony Puntoriero on Friday night after missing the cut at the Sony Open.

The 43-year-old believes he was drugged before being taken to an underground car park where he was knocked out, robbed and thrown into the boot of a car.

He was later dumped about 10km away from the abduction site.

Speaking on Monday, Allenby, who has bruising and cuts to his nose and forehead, said he had no memory of the attack.

“I have no recollection of being in the boot of the car because I was knocked unconscious straight away,” Mr Allenby told the Seven Network.

“I still don’t know if I was robbed before or after, but obviously everything I had in my possession was taken.

“My buddy got distracted and I went to the bathroom, and when I came out of the bathroom some people had said that my buddy had already left,” he said.

After leaving the restaurant, Allenby said he “walked around the corner, then `bang'”.

“The next minute I was thrown out of the boot of a car … on to the side street,” he said.

The golfer said the police and FBI were currently working on the case, and it wasn’t clear if the attack was targeted.

But he said police had found that one of his credit cards was used in Waikiki on Sunday night.

“Whoever did it is definitely still around, still in town,” Mr Allenby said.

He paid special tribute to a homeless woman who helped him as he was starting to be harassed by other homeless people after being dumped out of the car.

The homeless woman got the bruised and beaten golfer away from the others, before a retired military officer also came to his aid.

“I was very fortunate, a homeless lady pretty much saved my life,” Allenby added.

Scans have cleared Allenby of any serious facial or head injuries and he is hopeful of being cleared to fly in the next day or two.

He doesn’t yet know when he’ll next hit the golf course.

“The chances of me playing next week are very slim, but I’m just taking it one day at a time.”
