In June 2019, Green won her first major (and first LPGA Tour event), the Women's PGA Championship, by one stroke over defending champion Park Sung-hyun. It was the first wire-to-wire win at the Women's PGA Championship since Yani Tseng in 2011 and the first major win by an Australian since Karrie Webb at the 2006 Kraft Nabisco Championship. In winning the event, Green also became only the third Australian woman to win a major, after Webb and Jan Stephenson.
