The competition will be played in Penrith from today with teams playing one-day matches today, tomorrow and Wednesday to decide who will square off in Thursday's final.

"Western's results the last few years haven't been great.

"We've finished in that bottom part of the competition, seventh to 10th," Colley explained.

"I've had the majority of this side through the winter and with the Western Zone under 17s and they did well at 17s. I'm hopeful they can do well at CHS."

Grenfell's Henry Hunt will captain the side which also features Orange's Braden Riles and Matt Corben.

"Henry is a good leader and has decent cricketers around him," Colley said.

Western will have a tough test first up when they take on defending champions Sydney East today.

Western will then play South Coast tomorrow and North Coast on Wednesday.

The top two sides will play in Thursday's final while the remaining teams will have their opponents drawn out of a hat to play on the same day.

Players will be out to catch the attention of selectors as the NSW CHS firsts and seconds teams will be chosen from the championships.

A team will also be selected to participate in a two-week tour of the United Kingdom.

WESTERN: Braden Riles, Matt Corben (Orange), Henry Hunt (c-Grenfell), Stu Fredricks, Nick Chapman, Harry Ottley (Mudgee), Oliver Hoare (Nyngan), Cory Suckling, Warren Dodd (Dubbo Senior), Ben Pattinson (Dubbo South), Jeremy Judge (Kelso), Luke Hillier (Cobar), Callan Taylor (West Wyalong).
