American golfer John Daly grabbed a spectator's camera and smashed it into a tree during the first round of the Australian Open at Royal Sydney today.

Daly, who is heading for an early exit from the tournament, pushed his tee shot on the ninth hole - his final one of the round - and walked into a clump of trees when golf fan Brad Clegg tried to take his picture from close range.

It was the last straw for Daly, who was clearly frustrated at his lack of success in three tournaments in Australia this season.

After snatching the camera he stalked up to the nearest tree and hurled it with all his force into the trunk, saying "you want it back, I'll buy you a new one".

As Daly completed the hole Mr Clegg, a 15-handicapper at Sydney club Ashlar, was left to pick up the pieces - literally.

Mr Clegg, who had taken a leave day especially to see Daly play, said it was a disappointing way to finish the day.

"It hasn't ended well," he said.

Asked if he would be seeking compensation, Mr Clegg said: "I don't think I'll be chasing him for the money. He's a big bloke".

Mr Clegg said he had come out specifically to watch Daly because it might be the last chance he has.

"It was very unexpected," he said.

Mr Clegg said he did not think he had provoked Daly.

"I was bold but I wasn't unreasonable," he said.

Daly shot a 6-over-par 78 and will need something special tomorrow if he is to avoid missing his third cut in as many weeks.

He was paid appearance money to play on the Australian circuit this year and while organisers believe he has pulled people through the gate he has not delivered results on the course.
