The Raiders secured a 6-0 victory over the Tigers, advancing to the NRLW Grand Final with Isabella Waterman's try.
The Raiders are one win away from a spot in the NRLW Grand Final after one try was enough for the Green Machine in the lowest-scoring game in competition history.
Points were at a premium in Campbelltown as Canberra held on for a 6-0 victory over the Wests Tigers who have been knocked out of the finals after they ended the club's 15-year drought.
The Raiders were too good for the Tigers a week ago and made it back-to-back victories thanks to an Isabella Waterman try 16 minutes into the contest.
It was a nice shift to the left for the winger to score, with veteran halfback Zahara Temara then adding a penalty goal in the second half after she was stripped following a big break down the middle.
Canberra's forwards laid the platform in their first finals appearance where Chloe Saunders was just about the best player as she dominated through the middle.
