Robyn Choi is the best-placed Australian and is in a tie for 19th, nine shots behind Woad, who shot a 5-under 65 to get to 11-under and take a three-stroke lead over second-placed Amanda Doherty into the final round.
"I haven't looked at the weather, but probably going to be a bit of wind in there, I presume," Woad said of the final round on Sunday (Monday AEST).
"Just try to hit as many fairways as possible again to give yourself opportunities, because if you miss the fairway you've kind of got to play defence."
Play was delayed for more than two hours in the morning on Saturday at Maketewah Country Club, the first-year venue that features par-3 closing holes on each nine.
Korda was also nine shots back in a tie for 19th after a 2-over 72 in her bid for a third straight victory.Â
She was in the final group in all six of her previous starts this year, winning The Chevron Championship and Riviera Maya Open in the last two.
Woad is trying to win her second LPGA Tour title after taking the ISPS HANDA Women's Scottish Open last year. The 22-year-old English player had seven birdies and two bogeys on Saturday (Sunday AEST), dropping a stroke on the par-4 17th.
Doherty, who shared the second-round lead with Jin Young Ko, birdied the 17th in a 69. The 28-year-old is winless on the tour.
Haeran Ryu was third at 7 under after her second straight 66. Lydia Ko was another shot back, shooting 69 alongside Woad.
Jin Young Ko shot a 75 to tumble into the group with Korda at 2 under.
Jeeno Thitikul topped the group at 5 under after a 69. She won the Mizuho Americas Open last week in New Jersey
Australia's Cassie Porter shot a 73 in the third round to be in a tie for 37th. Hira Naveed missed the cut.
