Green claimed a commanding four-shot victory in the TPS Murray River, chipping in to eagle the five-par 10th hole in the final round before finishing 20-under-par overall.
It was the second tournament win in as many weeks for the 25-year-old, after she won the Vic Open at 13th Beach the previous weekend.
Echuca professional golfer Reanna Matthews also competed in the event and said Green’s victory was a phenomenal achievement.
“It’s massive,” Matthews said. “I think a lot of us are sitting back going ‘I can’t believe this is history’.
“I don’t think we know how historic this is. I think we’ll look back on it and think ‘wow I can’t believe Hannah Green won’.
“I think a lot of people don’t understand how big that was. It’s all around the world at the moment, on news everywhere — which it should be, it’s historic.”
Matthews said she had a feeling Green would be able to make history heading into the event.
“I thought Hannah would do it, I really did expect her to be up there,” she said.
“Her putting, her short game — her game is another level, so I did expect her to win. After those first two days I thought she was going to win.
“Being involved in a historic event, I am really proud that I can say I played in that event that Hannah Green won and made history.”
The TPS Murray River was Matthews’ first event back on the golf tour after a four-year break from the sport.
Matthews said it was still great to be out competing again after such a long time off.
“It was such a good experience, it was fantastic,” she said. “The vibe out there was amazing.”
“The whole atmosphere of the event, it’s another level. I actually forgot what it was like to be out there.”
While she washoping for a top-10 finish, Matthews missed the cut after her opening two rounds.
But despite not hitting her target, she was still looking on the bright side.
“I was disappointed, I’m not going to lie,” she said. “But you’ve got to take the positive out of anything.
“Unfortunately, I just had too many shots too early on that left me playing catch up and I just couldn’t get back.
“The first round I had two double bogeys early on and then it’s really hard to make that up.”
She said she was proud of the resilience she showed throughout the event.
“I was really proud of my determination to finish off well,” she said.
“When you make two double bogeys early on, you can get into that negative zone and you just go worse and worse.
“I was in fight mode for the last nine to 12 holes, and I was proud of myself. I just made birdies where I could and made the most of it instead of just washing away.”
The tournament had an extra special connection for Matthews too. It was played in honour of Jarrod Lyle, a professional golfer from Shepparton who passed away from leukaemia in 2018.
Matthews said it was nice to take part in an event in his memory. She wore yellow on the Friday in honour of Lyle, and she said other pros did the same.
“It was such a nice atmosphere and I think all the pros were really respectful,” she said.
“It was just such a nice feeling going out there and playing in memory of him.
Looking ahead, Matthews sees a few Pro-Ams in her future as she works her way back into golf and tries to get her ranking up.
“It’s definitely motivated me to practice more and play more,” she said.
“I want to play in a lot more events.
“I forgot how much I really enjoyed it and why I started golf in the first place, because I loved it.
“I definitely want to get back out there and compete in more events.”
