Green is teeing it up for only the second time this year, one of five Australians in the star-studded 69-player field at the LPGA Tour's $US2.4 million event at Sentosa Golf Club.
The world No.6 has returned to women's golf's so-called "Major of Asia" with fond memories and feeling good vibes.
Green notched birdies on the last three holes last year to snatch victory from Celine Boutier and become only the fifth Australian to win five times on the LPGA tour.
"I practised yesterday and I played the back nine and just remember obviously the last three putts that I made on 16, 17 and 18. Recreated the putt on 18," she said.
"Yeah, my face is everywhere - in the hotel, on the golf course, in the city. So it's unusual to see it everywhere but obviously gives me a lot of confidence, and hopefully I don't put too much added pressure on to myself.
"But this is a place that I've had not only a win but some good finishes so I'm looking forward to a title defence."
The 28-year-old has recent experience going back to back.
In addition to saluting in Singapore last March, Green successfully defended her LA Championship in May before clinching a third title of the year with another one-shot triumph over Boutier in the BMW Ladies Championship in South Korea in October.
No wonder she has lofty ambitions for 2025.
"Most players have goals throughout the year and because I did achieve winning three tournaments, it's hard to then reset," Green said.
"So I guess another thing that I've been thinking about with my coach is obviously where my world ranking is and, realistically, with Nelly (Korda) winning as many times (eight) as she did last year, I don't think I can achieve No.1 unless I win the same amount of times.
"Would love to get to world No.2, world No.3. It is hard to back up a successful year.
"Don't want to put too much pressure on myself. But it does bring a lot of confidence coming to events that you've played well at before."
The 2019 Women's PGA Championship winner also wants to contend at all of this year's majors after missing the halfway cut in two of the five big ones last season.
"Unfortunately I didn't play a lot of weekends last year, and those are the tournaments we try to prepare the best for and I put too much pressure on myself to perform well at those events," Green said.
"I'm hoping this year will be a better season in that sense. I've just got to use the confidence from the last couple years."
Green will play the first two rounds in Singapore with Thailand's world No.2 Jeeno Thitikul and New Zealand superstar Lydia Ko.
"It's almost like a home event. This is the same time zone as where I live and only a five-hour flight," Green said.
"It's the closest LPGA that we have to my home city so there's lots of people that come from Perth that travel up and my husband is also here this week, which is nice. There's lots of good memories."
Minjee Lee, Steph Kyriacou, Grace Kim and Gabriela Ruffels also feature in the rare no-cut event.
