The four-time European Champion and world No.5 posted rounds of 78, 82 and 73 to claim the inaugural championship at The Lakes in Sydney.

Remarkably, Kammerstad - who has a difference in leg length - beat 25 players from the Australian Open who were playing from the same tees with his final-round score on Sunday.

The one-over par effort included five birdies.

"I'm really pleased," Kammerstad said.

"Of course that was a main goal, to win, but I know the guys are good so I have to be at my best to beat them."

Kammerstad paid tribute to the vision, particularly of Christian Hamilton, that brought the tournament to life.

The event was the first of its kind staged concurrently with a national open, with the players left overwhelmed by the generous support of the Sydney galleries, especially at the par-5 14th on Sunday.

"There were a bunch of guys up there, I hit a 7-iron to a metre and I thought the roof was going to come off," Kammerstad beamed.

"My coach has it on video, so it's going to be fun to watch.

"I don't want to compete again unless it's on these conditions.

"It was very special. I hope it stays the same - it's perfect."

The best-placed Australian in the field was The Lakes' club member Geoff Nicholas, who finished 14 shots back at 31 over for the 54 holes.
