The in-form West Australian rolled on at Gold Coast's Sanctuary Cove on Friday, shooting an eventful four-under 67 to sit alone at 10 under entering the weekend.
It follows a breakthrough triumph at the Australian Open in Adelaide last Sunday and victory at Singapore's Women's World Championship, her seventh LPGA title.
Victory at the $600,000 event would secure a unique Australian golfing double, given the Karrie Webb Cup has only been contested once before.
"I'm probably putting more pressure on myself as I am obviously on such a hot run," Green said.
"Perhaps if I didn't win the last two events, I would maybe fly under the radar a little bit more.
"We still have a really strong Ladies European Tour (LET) field, so it's not like I have it easy this weekend.
"There's going to be a lot of good players ... chasing me and probably have less pressure on themselves."
Bogey-free on Thursday, Green's second round was far more colourful as she mixed six birdies and an eagle with a double bogey and another dropped shot.
She had three birdies in four holes to jump clubhouse leader Meghan MacLaren (eight under) before finding the water on the par-three sixth and carding a five.
But Green responded by putting her second shot on the par-five seventh within eight feet of the flag and nailing the eagle putt.
Another long-range birdie putt on the 13th edged Green further ahead, although Germany's Alexandra Forsterling holed a monster of her own on 18 to card a five-under 66 and finish three back.
"It was definitely a roller-coaster ... hopefully I can go back to playing a bit more boring golf," Green said, despite admitting she would continue playing "aggressively as possible".
England's MacLaren (68) held onto second while Harang Lee, Alessandra Fanali, Vanessa Knecht and Casandra Alexander were a shot adrift of Forsterling at six under.
MacLaren will embrace the chance to chase down major champion Green, who has skipped a lucrative LPGA event to compete, on Australian soil.
"Whenever you bring that (a major winner) to an LET event, I think it just elevates the whole thing," she said.
"It's really nice to see them support their own country and their own tour ... It's inspiring for everybody on the LET to go, 'That's the level and can we compete?'.
"There's probably a fair bit of pressure on them to come and perform here, so I think they deserve a load of credit for being here."
Aussie Hannah Reeves backed up her first-round 67 with 70 to sit at five under, while compatriot Sarah Kemp was a shot further back.
But LPGA talent Steph Kyriacou's tough run continued, missing the two-over cut line by five shots after also missing the cut in Adelaide.
