Canberra's strong performance boosts NRLW title hopes; Gold Coast faces Brisbane while Sydney Roosters seek to continue dominance.
Canberra handed Brisbane their heaviest defeat in August and lost to Gold Coast by just six points, bolstering the Raiders' case as NRLW title contenders.
Gold Coast, winners of 10 consecutive games, face defending premiers Brisbane in Sunday's other preliminary final.
The Raiders meet Sydney Roosters on Saturday night at Allianz Stadium, where the visitors are favourites after a second straight unbeaten regular season.
Sydney have won 27 of their past 28 games since mid-2024, with Brisbane responsible for their only loss, in last year's decider.
