Kelsey got her spot in the final against state team-mate Grace Kim after a roller-coaster afternoon at the St Michael's Golf Club, Sydney.

With the temperature nudging the 40'son Thursday it was the cool calm and collected Bennett who put on a clinical display dispatching the British Women's Amateur Champion Emily Toy 4 and 2.

"I'm stoked, really stoked," Bennett said after the round.

"I figured she would be pretty good in the wind, coming from Great Britain, playing on links courses."

A St Michael's member, Bennett admitted the key for both of her wins was her local knowledge.

"I know you have to stay smooth with the wind out here, rather than trying to over hit. They will balloon, and that is the worst thing you can do," she said.

" I knew the spots on the greens to aim for, and I planted my approach shots there."

Bennett is looking forward to today's final, and the prospect of facing Kim is a daunting one. Bennett knows it will take her best to beat the world number 78.

"I'm just going home to sleep," she said after Thursday's tough match.

"I won't be leaving anything on the table at all, and I'll be giving it my all." Bennett smiled.

Kim, in contrast, ended up in a battle royale against the never say die Queenslander, Sarah Wilson.

After dispatching 12-year-old Ann Jang in the morning, Kim faced the more experienced Wilson in the afternoon.

With the lead barley swinging more than a hole either way throughout the afternoon, the pair came to the 18th all square.

With the pair on opposite sides of the fairway, Kim, first to play rifled her approach to about 15 feet over the flag.

Wilson couldn't respond, missing short and right of the green, and after hitting a good - but not great chip to about six feet, she left Kim with a putt for the match.

Kim couldn't convert, and when Wilson slotted her par save, the match was off to extra holes.

The pair traded pars on the first before heading to the second. Kim, with the honour, smashed a metal wood to within 75 metres of the green, but Sadly for Wilson, her tee shot went left and into trouble.

After being forced to take an unplayable, it was always going to be tough for Wilson, and when she failed to make the green, it was all but over.

After hitting the green, Kim calmly two-putted for par, and she was into her second NSW Amateur final in as many years.
