St George Illawarra's quest for a maiden NRL women's premiership has fallen short, with the Dragons going down 30-6 to Brisbane in the grand final on Sunday.
The Dragons were outclassed as the defending premiers made it back to back titles at ANZ Stadium.
Brisbane downed St George Illawarra 14-4 in the opening round of the competition and went into the decider with plenty of confidence they could repeat the result.
That result had left the Dragons playing must-win football for the second and third rounds of the competition to make the grand final, with St George Illawarra hopeful they could continue their momentum.
But they were unable to keep the run going as the Broncos burst out of the blocks.
Lavinia Gould had Brisbane in front after just three minutes, with the hooker jumping out of dummy half and showing good footwork to score in the corner.
The Broncos were out to a 10-0 lead midway through the first half thanks to former Dragon Raecene McGregor's outstanding solo effort.
With Brisbane attacking the Dragons' line, Gould fired a pass to McGregor out of dummy half with the five-eighth dancing between three St George Illawarra defenders to slam the ball down.
It could have been worse for the Dragons after Brisbane had another try disallowed on the stroke of half-time.
McGregor hung a kick up for Meg Ward, with the winger catching and touching down in the corner, only for the video referee bunker officials to disallow the try for a questionable obstruction.
It had been all Brisbane in the first half, with the Broncos enjoying 63 per cent of possession, with three quarters of the match played in the Dragons' half.
St George Illawarra were also hit hard with injuries. The Dragons lost Maddison Weatherall and former Bronco Brittany Breayley to knee problems and it got worse after half-time, with halfback Maddie Studdon suffering an elbow injury.
Brisbane extended their lead to 12-0 with a penalty goal before sealing the result with a try to Julia Robinson 10 minutes into the second half.
A slick short side raid saw Broncos captain Ali Brigginshaw fire a perfect cut out pass to Robinson to dive over in the corner.
Tries to Chelsea Lenarduzzi and Amber Pilley had Brisbane out to a 30-0 lead as the depleted Dragons lost Hoilli Wheeler and Takilele Katoa to shoulder injuries.
The Dragons finally got themselves on the board with 10 minutes to play when Studdon produced a beautiful short pass for captain Kezie Apps to barge over from close range for a consolation try.
Brisbane Broncos 30 (Lavinia Gould, Raecene McGregor, Julia Robinson, Chelsea Lenarduzzi, Amber Pilley tries. Meg Ward five goals)
