The new Australian Open champion Aaron Baddeley says he is confident he can beat the professionals again this week in the Players' Championship in Brisbane.

"I want to go out and win again. I wouldn't be here if I wasn't planning on winning," the 18-year-old amateur said yesterday.

Baddeley became the first amateur in 39 years to win the Australian Open at Royal Sydney beating five-times winner Greg Norman and fellow Australian Nick O'Hern by two strokes.

He has also revealed he has turned down an invitation to play the Australian PGA Championship at the Victoria GC in Melbourne - his home town - next week because he will need a break.

His father Ron Baddeley was keen for him to play this week because he thought it a good lesson to learn what it was like to back up after a win.

Ron Baddeley is determined to make sure the millions of dollars awaiting his son when he decides to turn professional do not cloud their plans for another season playing overseas as an amateur.

While dozens of agents would willingly offer more than a million dollars to get Aaron's signature, he has told them all he's not interested at the moment.

"We won't be making a decision this year (on turning professional), we won't be making a decision early next year," said Ron Baddeley. "The earliest we'd think about it is after the Australian series."

"The reason we don't want money flashed up is because it can make the decisions so difficult, it can really cloud your thinking at times when money is put up.

"I just feel that in Aaron's best interests it's best not to start talking about money or that glamour life and just to stick with our plan."

Elsewhere, Englishman David Howell will not be defending next the Australian PGA title in Melbourne.

Howell headed home on Monday after finishing 24th at the Australian Open. Howell's first professional title was the Australian PGA, which he won by seven strokes at the New South Wales Club in Sydney. But contesting 30 tournaments in Europe this year has taken its toll on the 24-year-old.
