Sydney Roosters booked a Grand Final place with a 20-10 win over Canberra in Saturday night's Preliminary Final at Allianz Stadium.
The undefeated Minor Premiers struck within two minutes, when Jayme Fressard crossed in the corner after an early penalty.
Jocelyn Kelleher missed the conversion, but Sydney extended its lead to 10-0 through Rima Butler, who finished a quick pass from Keeley Nizza.
Canberra's defence held firm through sustained pressure, and Krystal Blackwell put the Raiders on the scoreboard just before halftime.
Zahara Temara supplied the pass, and Blackwell broke through to score; the conversion failed, leaving Canberra 10-4 behind at the break.
Jessica Sergis restored Sydney's 12-point advantage after gathering a long kick and scoring beneath the posts, with Kelleher converting.
The Raiders responded when Hollie-Mae Dodd dived over after receiving Chante Temara's pass from dummy half.
Zahara Temara converted to make it 16-10, but Tarryn Aiken broke through late to seal the Roosters' victory.
Canberra had entered the contest confident and continued searching for chances, but could not overcome the eventual Grand Finalists.
