The Broncos are the only team to have lifted the NRLW trophy and they're aiming for a three-peat when they face the Roosters at ANZ Stadium on Sunday.
Brisbane, who have lost just one match in their NRLW history, beat their opponents in a dress rehearsal of the decider in round three.
Coach Kelvin Wright thought the Broncos "played within themselves" in the 24-16 victory, but the Roosters will regain troops and showed plenty of promising signs with some expansive footy.
The teams met in the 2018 grand final, with Brisbane prevailing 34-12 before smashing the Dragons in last year's decider.

Ali Brigginshaw v Zahara Temara. Whether at halfback or lock, Brigginshaw is undoubtedly Brisbane's chief playmaker and has been in typically sparkling form. Temara is a huge attacking threat with the ability to score tries, set them up as well as kicking goals.
The Broncos have won their two grand finals against the Roosters and Dragons by a combined margin of 64-18.
