Members of a golf club in Australia have something more to worry about than just their swing, playing on what is thought to be the world's first shark-infested course.

Six man-eating bull sharks live in the lake in the center of the course at Brisbane's Carbrook Golf Club, where their fins poking through the water has become a regular sight.

The sharks, which are between 8ft and 10ft long, got onto the Queensland golf course when it flooded some years ago after a river broke its banks.

They became stranded when the water receded, but now they are thriving and even breeding, Sky News reported.

"You can't believe how close you are ... just six feet [1.8m] away," club general manager Scott Wagstaff said.

"There's no drama, it's become a positive thing for the golf course. They are amazing. I've become a shark lover since working here."

Although the lake is well stocked with fish, Wagstaff occasionally throws in meat to encourage the sharks to come near the surface.

"I'm sure they are aggressive when you are in the water but when you are out here feeding them they are beautiful to watch," he said.

The sharks have become renowned in the region and there is even a monthly tournament called the "Shark Lake Challenge."
