The 20-year-old from Perth fired a brilliant final round 64 on Monday US time to finish the season-ending Symetra Tour Championship in Daytona Beach, Florida in 5th place and rise to 2nd on the season-long money list.
Green - who said all year that her goal was to win three times - recorded 12 top-10 finishes including her victories, making her one of Australia's most intriguing players to follow when she tackles the highly lucrative LPGA Tour early in 2018.
"Hopefully I just have a really good year next year, I'm not expecting to win like I said this year," she said after a ceremony in Florida to present the Symetra Tour's top 10 money earners with their tickets to the LPGA.
"Obviously it's a completely different tour so I just want to play well and have a lot of fun."
HANNAH GREEN REFLECTS ON ROOKIE YEAR
Green's wins at the Sara Bay Classic in April and pair of victories in September at the Murphy USA El Dorado Shootout and IOA Golf Classic meant she had alread secured her LPGA card several weeks before the Tour Championship.
But her strong end in Daytona Beach to an outstanding maiden pro season also helped her earn Symetra Tour Rookie of the Year honours.
Green will tee it up next week against the men at the WA Open at Royal Perth.
The Mount Lawley Golf Club member said her goals for 2018 are yet to be determined.
"Obviously I have to reassess now that I have my [LPGA] card. I can't set anything just yet but when I go home, I'll have some off time and speak to my coaches and my support crew and we will set goals.
"It definitely hasn't sunk in even though I sealed my card three weeks ago. I thought the ceremony would do it but it really hasn't sunk in. I guess in the Bahamas, when I'm travelling over there, it will probably sink in then.
"It's pretty cool to think I'll be on the LPGA next year," Green said.
"My time on the Symetra Tour has been a big learning experience about my golf game and about myself as a person. I'm glad I got to spend this time on the Symetra Tour in order to get to the LPGA."
