Following her stunning victory at last month's KPMG Women's PGA Championship Green returned home to Perth to savour the win, taking two weeks off and has used the past fortnight to work with her swing coach Ritchie Smith.
"I'm feeling pretty good and it's just really nice to be back out here. I feel like a month was needed," Green told the LPGA on the ground at Evian Resort Golf Club in Évian-les-Bains.
Green - a member at Mount Lawley Golf Club in Perth - said she's also getting used to being recognised by more people, particularly at golf clubs in her home city.
"I think I've accomplished something really big so it's just really nice to be recognised."
This week will be a first for Green in the sense that she's part of a marquee LPGA Tour group.
The 22-year-old will play the opening two rounds with a pair of South Korean 2019 major winners, ANA Inspiration champion Jin Young Ko and US Women's Open winner Jeongeun Lee6.

Green - who is exempt for the next five LPGA Tour seasons - said her major breakthrough came despite a slight drop off in the quality of her ball-striking.
"During the KPMG I putted really well and my scrambling was really good so my ball-striking wasn't as good as it had been at the start of the year so that's kind of what we've been working on."
Green missed the cut on the number at last year's Evian Championship with rounds of 77 and 69 on the famous par-71 layout.
Her recent time spent with Smith has been focused on curbing a long-term swing tendency.
"My left arm gets really trapped and low in my backswing so I've just been trying to make sure that that gets a little bit higher so that I can actually generate more speed and hit a little bit longer.
"It's been probably my project for my whole entire career and I'm sure it will be for the rest of my career as well so just making sure I tweak that and keep on top of that for the rest of the season and obviously the rest of my career."
Green is among five Australians in the field at Evian and will be joined by World No. 4 Minjee Lee, Su Oh, Katherine Kirk and Sarah Kemp.
