Australian star Gabi Ruffels is poised to make more golfing history next month.

Ruffels, 20, became the first Australian to win the US Women's Amateur crown last year.

And as she prepares to defend her title in August, the Victorian is breaking new ground again.

The University of Southern California star has agreed to play in the Jacksonville Amateur Championship late next month.

It will make Ruffels the first woman to play in the 59-year history of the event.

"I thought it was a great opportunity to test my game before the Women’s Am," Ruffels told Golf Channel.

"The women’s amateur schedule has been very restricted with everything that’s going on, so it has been tough to find women’s amateur events."

Ruffels, currently No.11 in the World Amateur Golf Rankings, will play from the same tees as the men on the Jacksonville Beach Golf Club course that measures approximately 6100m.

The 2020 US Women’s Amateur is scheduled for 3-9 August at Woodmont Country Club in Rockville, Maryland.
