Sydney Roosters crushed the Brisbane Broncos 30-6 to complete the perfect season and claim a third NRLW premiership title.

The unstoppable Roosters gave legends Corban Baxter and Millie Elliott the perfect send-off with six tries in a first-half blitz at Accor Stadium.

Sydney won all 11 of their regular-season matches before claiming victory in both finals to complete a perfect season.

Brydie Parker (2), Tarryn Aiken, Isabelle Kelly, Jayme Fressard and Amber Hall all crossed the whitewash as the Roosters produced a dominant first-half display.

Parker completed her Grand Final hat-trick before the hour mark to extend Sydney’s lead to 30-0.

Jesse Southwell finally got the Broncos on the board after 63 minutes, but the game was already done and dusted, with the Roosters soon celebrating a crushing victory.

Retiring Roosters forward Millie Elliott said: “Everyone knows what that felt like and we definitely used that as motivation all season, not just in this game, all season,” she said.

“And we worked so hard, I take my hat off to [head coach John] Strangey and the coaching staff, they really left no stone unturned this year and we wanted to put in a performance like that.”

Winning captain Isabelle Kelly said: “I knew that this year we’re creating something special, and I think we’re building and made that our best game yet. I love you guys and I’m so glad that we get to do this together.”

She added: “To Corban and Millie, you guys have been absolutely incredible for this NRLW competition, but mostly for the Roosters the impact that you guys have had on us, Millie, you being a mum, it’s just created such a special bond for us to look forward to for many years. And you’ll always be a Rooster.”
