Brisbane have all but qualified for their second-successive NRLW grand final, with Ali Brigginshaw leading the Broncos to a 20-0 trouncing of the Sydney Roosters.
If the Broncos weren't already the team to beat, they confirmed it by dominating what was a rematch of last year's decider, putting a sloppy and wasteful Roosters to the sword on Saturday at AAMI Park.
It leaves the Roosters' season on life support and they will be knocked out of contention if the Warriors beat St George Illawarra on Sunday.
The Broncos remain undefeated, having won all four games on their way to last year's title and opening their account with two victories in 2019.
They would need to lose to the Warriors next week and have results run against them to miss out on this year's decider.
Halfback Brigginshaw orchestrated the rout, setting up Annette Brander's opening try before putting the icing on the cake in the second half with a chip-and-chase solo try.
Her kicking game was also hugely influential in wet and difficult conditions, pinning the Roosters down their own end for long periods.
Brigginshaw finished the game with ice on her right knee after coming off with five minutes to go, but coach Kelvin Wright described it as a precaution.
"It was a bit more of a scare than anything. She's moving around alright in the sheds," Wright said.
"Hopefully, nothing too serious.
"She had another fantastic game in tricky conditions, her and Raecene (McGregor) kept getting us to the right end of the field."
Prop Millie Boyle was also immense, running for 113 metres, while Roosters starting front-rowers Ruan Sims (16m) and Vanessa Foliaki (6m) had just two and one runs respectively.
The Roosters' day was summed up when Amber Pilley strolled through some soft defence to make it 10-0 after 10 minutes.
They were their own worst enemies in the first half, not completing their first set until the 20-minute mark.
They picked up where they left off after the break with winger Kiana Takairangi allowing the kick-off to trickle into touch.
And from the next set, lock Rona Peters crossed to effectively seal the result.
"It was frustrating to watch. We got a bit of lesson in wet weather footy," Roosters coach Rick Stone said.
"They played pretty consistently; didn't take too many chances; got to their kicks well.
"We just gave the opposition possession and field position time and time again with some fundamental errors."
