Sydney Roosters defeated Brisbane Broncos 30-6 in the 2026 NRLW Grand Final at Accor Stadium, Sydney, on Sunday, 4 October 2026, to win their third NRLW premiership and complete an undefeated season.
The victory capped a perfect 13-0 campaign for the Roosters, who did not lose a match all year on their way to the title.
Sydney ran in seven tries to Brisbane's one. The Roosters led 26-0 at half-time, the largest half-time lead recorded in an NRLW Grand Final.
The 30-6 final margin equalled the biggest winning margin in an NRLW decider.
Brydie Parker scored a hat-trick, crossing three times in the win.
Tarryn Aiken won the Karyn Murphy Medal for best on field. Jocelyn Kelleher was also among the Roosters' best on the day.
Brisbane were the defending premiers, having won last year's Grand Final 22-18. It was the second consecutive year the decider had been contested between the Roosters and the Broncos.
Departing Roosters players Corban Baxter and Millie Elliott were farewelled by the club after the match.
The NRLW decider was played before the men's NRL Grand Final at Accor Stadium later on Sunday, in which the Newcastle Knights faced the Sydney Roosters.
