The Knights will play Nestles in the final on Sunday at Mack Oval. 

This is the third year of the competition, with Woodford the inaugural premier in 2016-17 and Nirranda saluting last year.

Nirranda made Sunday's final after a 29-run semi-final win over Brierly-Christ Church.

Sophie Walsh (30 retired) led the way with the bat, while Taleisha Ryan (2-8) returned the best bowling figures.  

In the other semi-final, Nestles defeated West Warrnambool by seven wickets.

Nestles opener Ella Couch made 33 not out as her team racked up 3-91, in reply to the Panthers 4-71. 

WDCA president Gordon McLeod is encouraging the cricketing public to come along to the final.

"It has been a fantastic competition all year," McLeod said.

"Anyone who comes along on Sunday will be pleasantly surprised when they see the standard the girls are playing at.

"There is a lot of talent in both teams.

"It will be a tremendous showcase of girls cricket at the Mack Oval, which is the home of girls cricket in Warrnambool."

The WDCA boys under 17 competition is also coming to the pointy end of the season.

Semi-finalists have been decided with West Warrnambool to play Koroit and Brierly-Christ Church to take on Woodford. 

Day one of the 45-overs a team semi-finals will be played on Tuesday.

"A lot of the boys in these games are playing senior grades for their clubs so it is terrific cricket," McLeod said.
