Limits? Min Woo Lee isn't subscribing to them as the new Australian PGA champion aims to become the No.1 golfer in the world.

The 25-year-old stormed home by three shots at Brisbane's Royal Queensland on Sunday, winning fans with his swagger and style that have now netted him four career titles.

The victory was Lee's second in four starts after a Macau Open triumph and the West Australian is already eyeing bigger and better things next year.

"Limits? I don't think so. I've proven to myself I can play really good and win," he said after being projected to rise to a career-No.38 in the world.

"No limit. I want to be the No.1 player in the world. It's still a long way away, but I'm on the right track."

Lee tied fifth at the US Open this year and was in the final pairing on his Players Championship debut, eventually finishing sixth.

He can't wait to play another major and is now gunning for a Presidents Cup and Olympic berth.

"I'm really close to doing well in the big majors and tournaments," he said.

"A couple of times I let it slip.

"I'm really excited, can't wait for those majors; I've found my craft and I'm starting to mature into it."

Lee will play in Sydney's Australian Open from Thursday alongside his world No.5 and dual major-winning sister Minjee and has promised himself not to celebrate too hard before flying south.

"I can win again," he said after having his name etched alongside legends like Greg Norman, Adam Scott, Cameron Smith, Seve Ballesteros and Peter Thomson on the Joe Kirkwood Cup.
