The Orange girls accounted for Nepean 6-0 this morning before toppling Newcastle 5-2 on Saturday afternoon.

The two wins meant Orange finished second in their pool and will move into the semi-finals on Sunday.

Orange under 18s coach Mel Hope was thrilled to see her side earn a place in the top four in the state.

"They've already done better than last year," Hope smiled.

"They've done brilliantly."

Hope said the girls' win again Nepean was "not very flash", but Orange was a different side when they took on Newcastle this afternoon.

"They came out onto the park as underdogs this afternoon and they dominated Newcastle from the start," Hope said.

"I can't fault their game."

On Friday, Orange lost to Lithgow 4-0, before bouncing back to topple Macarthur 4-3.

Orange's semi-final will start at 9.15am on Sunday.
