While some of the biggest names in men's golf have shunned this year's Games, as well as Rio in 2016, Green will make an almighty sacrifice to tee off in Tokyo.

The 2019 KPMG Women’s PGA Championship winner will not only forego the chance to land a second career major at next month's Evian Championship in France, but also put herself through two weeks in quarantine for the honour of representing Australia, which will be confirmed after this week’s tournament marks the conclusion of the qualifying period.

Green will fly home to Perth, via Sydney for her 14 quarantine period, on Monday, straight after finishing this year's Women’s PGA Championship in Atlanta, to prepare.

Her likely Australian teammate Minjee Lee will avoid quarantine after opting to fly to Europe for the Evian Championship, then head to Japan, while Green is placing all her focus on Games glory.

"It's the tournament I am prioritising. I am going back to Australia on Monday so I can be as fresh as possible for the Olympics," Green said in Atlanta, where she carded an even-par opening round of 72 on Friday.

In addition to the trophy, the Evian is offering $US4.5 million in prize money but 24-year-old Green craves a medal more than a major.

"Because it is so rare to get a gold medal, once every four years," she said.

"Obviously winning a major is still hard, even though we have five chances a year. It's hard to get your name on a trophy.

"But I think everyone would notice, not just the golfing world would notice, if you won a medal."

"It's the tournament I am prioritising. I am going back to Australia on Monday so I can be as fresh as possible for the Olympics." - Hannah Green.

Karen Lunn, the WPGA Tour of Australasia boss, says she hasn't heard of any of the world's leading females who are skipping the Olympics.

Among the men's heavyweights not going are major winners Dustin Johnson, Adam Scott, Sergio Garcia, Martin Kaymer and Louis Oosthuizen and English players Tyrrell Hatton, Lee Westwood and Matthew Fitzpatrick.

Green "can understand where they're coming from" but says it's still disappointing.

"I guess it's just the money that they're playing for every week," Green said.

"I think we (women) play for great money (but) those guys can retire when they're finished with their careers.

"But most of us on Tour are going to have a family or move on to something else that we want to do.

"So I think that perspective has probably changed – playing for money versus a medal.

"I don't know, I'd rather a gold medal than a huge pay cheque because hopefully I just keep playing well and that will come with it."

Green also hopes COVID-19 might be playing a role in the men's no-shows, as the Zika virus did five years ago in Rio.

"It is a tough choice and I guess those guys (sitting Tokyo) out are going to try and compete in 2024 in Paris," the World No.15 said.

"Paris will be a pretty cool place to play so maybe that will entice people a bit more."
