Brigginshaw is set to make her final NRLW appearance for the Broncos on Sunday, bringing her nine-season, 67-game stint with Brisbane to a close.
Brisbane will meet the Sydney Roosters at Accor Stadium in the 2026 NRLW Grand Final, the club's fifth appearance in the decider.
Coach Scott Prince has named an unchanged line-up for Sunday's match.
The Broncos' squad has also remained largely consistent through the back end of the 2026 season.
Kick-off is at 3pm AEST (4pm AEDT).
