The 24-year-old, self- trained runner was incredulous and lost for words after leading the women's field from start to finish in a winning time of 14.56.

Hobart teenager Lily Castle finished second off her mark of 9.25m with Launceston's Abbey de la Motte third from 7.25m.

"I was not expecting that at all," an excited Boustead said after her victory.

"I thought there were some good runners in the field who had been here before and won here so I thought my chances were hard.

"It was very breezy but I'm a 400m runner so I thought that would be to my advantage.

"I'm stoked - I've never run that fast in my life I can tell you that."

Boustead said she was not really aware of where the other runners were during he race being the front marker.

"I thought to myself they are right there so just run.

"I've won a 200m at Meadow Glen in Melbourne but I've never won a gift before - it is my biggest win and the best feeling in the world."

Boustead has only been running professionally for two years and finished third at the Bay Sheffield Gift in South Australia before Christmas.

"That was a shock but to come first now - I can't put words to it sorry," she said.
