The 20-year-old - who finished tied for seventh at the Women's Amateur Asia-Pacific less than two weeks ago - will compete on Hong Kong Golf Club’s Old Course amongst a 123-player field headlined by Hong Kong's highest ranked golfer, LPGA Tour player Tiffany Chan.
"Getting this sponsor invite is so beneficial to my career and a stepping stone for bettering myself to turning professional," Kay said.
"Playing big professional events like the EFG Hong Kong Ladies Open, you get the opportunity to become comfortable with the atmosphere around the fans and media attention.
"I played the Queen Sirikit [Cup] a few years ago at the Hong Kong Golf Club, but I don't think it was the Old Course. Anyhow, I remember I really liked the golf course."
Kay is no stranger to strong performances against professionals.
On a RACV Royal Pines Resort layout she's very familiar with, Kay finished third at the 2017 RACV Gold Coast Challenge and was equal sixth at the 2015 RACV Ladies Masters as a 16-year-old.
Kay - whose decorated amateur career also includes a T6 finish at last year's World Amateur Championships in Ireland - said she might turn pro before the end of the year.
"Throughout my career I have been lucky enough to get some opportunities to play in a lot of professional events," Kay said. "My dream has always been [to be] a professional golfer and hopefully soon I can make the change, either at the end of this year or next. I am super excited."
“It feels awesome to know that the effort I have put in is being recognised internationally, and I am stoked and humbled to be given this chance by EFG when there are so many talented players they could have offered the invite to."
The Hong Kong Ladies Open is sanctioned by the China LPGA Tour, Taiwan LPGA and Ladies Asian Golf Tour, and is the only golf tournament in Hong Kong in which players can earn Rolex World Ranking points.
