The West Australian ended a 12-year drought to win the Australian Open in Adelaide on Sunday, enjoying a glass of champagne on the 18th green before jumping on the next plane to Brisbane.

That followed victory at the HSBC Women's World Championship in Singapore two weeks earlier.

The world No.7 will justifiably start as hot favourite at the $600,000 Australian WPGA Championship at Sanctuary Cove on the Gold Coast from Thursday.

"Momentum can work both ways, and in the middle of last year it was probably the opposite," she said.

"It was kind of hard to see the light at the end of the tunnel, but at the moment it feels like the hole's a lot bigger than what it actually is.

"So I just have to ride this as much as I possibly can (because) it's going to feel really quite sad when I don't have a win."

Green's Open triumph was the first by an Australian since Karrie Webb in 2014.

Coincidentally, the WPGA trophy is named after Webb and was won by Green's good mate Su Oh on its inaugural staging four years ago.

The tournament was due to return at Sanctuary Cove last year, before the threat of a cyclone scrapped it.

But it meant both Oh and Green could compete this year as part of a swollen women's domestic golfing calendar.

The pair, and fellow LPGA talent Steph Kyriacou - who Green will partner on Thursday morning - have opted to remain in the country instead of lining up in the $US3 million Founders Cup in California.

"This event does clash, but it's nice to be home," said Green, who won her sole major in 2019.

"It doesn't feel like an obligation. It just feels like something that makes me happy."

Sanctuary Cove's Palms course had been renovated before the event was cancelled last year, meaning it's had an extra 12 months to grow in.

Crediting her winning form to clutch putting, Green admits the grainy greens will test her in what will be the former world No.5's first visit to Queensland in seven years and her first event as a professional.

"The bunkering is quite tricky, because it comes into play for where we hit our tee shots," Green said of the challenges she's anticipating after playing 18 holes on Wednesday.

"So, obviously, avoiding those, but it seems like every green here you can't go long, so just making sure that you hit the right clubs (to approach the green)."

Early Ladies European Tour order of merit pacesetters Agathe Laisne - the recent Women's NSW Open champion and Australian Open joint runner-up - and Kelsey Bennett will bolster the field.
