At 12 years old Lilly Brown is already one of the country's top shooters for her age.

Gloucester's Lilly Brown is a young gun with a sharp eye.

In her first year as a member of the Gloucester Pistol Club she has placed first in the state and second in the nation for Western Action Shooting.

At just 12-years-old, 'Lethal Lilly' can shoot steel targets with a pistol, rifle and a double barrelled shotgun.

Like a scene out of a 1950's mid western town, Lilly dresses as a cowgirl and shoots at targets from behind doors and out of windows.

"She's as keen as mustard," Lilly's father Duncan Brown aka 'Bronco Billy' said.

"You have to be 12-years-old to achieve a minor's permit to shoot in this country but she's been dry shooting for years before that."

When Lilly was born she was diagnosed with a serious liver condition which meant that she had to spend three years in hospital.

"The first thing I said I'd do once I got her out of hospital was get her into the great outdoors," Duncan said.

"I taught her how to shoot and now she's a state champion and second in Australia."

Lilly Brown comes from a line of great marksmen.

"My father was an ex-policeman and he won the Police Games ten years in a row in shooting."

"He even won the Queens Shoot in 1964 in Australia when the Queen came to Sydney."

"He taught me to shoot and so we're just passing it down the line," he said.
