Roosters leaders Inika Tobin-Salzman and Isabella Rea believe their "united" 17 and under side is peaking at the pointy end.

But there's still another hurdle to clear. Tobin-Salzman and Rea are plotting the downfall of Koroit and are hoping to add another premiership to South Warrnambool's trophy cabinet.

"Last weekend, we just hit our primetime," Tobin-Salzman said.

Rea, the reigning Rebekah Moroney medallist who juggles 17 and under duties with open-grade minutes, echoed Tobin-Salzman.

The Roosters produced devastating form to thump Hamilton Kangaroos by 26 goals in the preliminary final.

"We have a really strong team all over the court and that has been a real strength of ours," Rea said.

"Our teamwork towards the end of the season has really lifted and we just feel united as a team.

"It's been a really positive season and coming in towards finals, things have picked up."

Tobin-Salzman, who has been exposed to division one netball this season, said teammates had benefited from senior experience.

"It's just about how far you want to go and every top-age girl moving up has the ability to (step up)," she said.
