Broncos debutant James Segeyaro scored the match-winning try to help the Broncos claim a much-needed 15-10 win over the Sydney Roosters at Suncorp Stadium on Friday night.
Segeyaro iced the result when he burrowed over from dummy half in the 70th minute as Brisbane claimed their fourth win this season.
The hooker wasn't the also standout player for Brisbane as Payne Haas put his hand up for a New South Wales debut with an inspirational performance.
Barnstorming 19-year-old Haas ran for 223m and scoring a first-half try as the Broncos remarkably snapped the ladder-leading Roosters' eight-game winning run in a bruising clash in front of a 28,288-strong crowd.
Haas belied his years to manhandle the highly fancied Roosters pack which was found wanting after losing their inspirational captain Boyd Cordner (concussion).
Haas - who also made six tackle breaks - dominated the Roosters to ensure Brisbane also extended the Tri-Colours' horror record at the Brisbane venue.
The Roosters have not tasted victory at Suncorp Stadium since 2014, losing six straight games.
Armed with just nine NRL games, Haas is on track to become the most inexperienced NSW player and youngest forward in Origin history if picked by coach Brad Fittler for next month's series opener.
It marked the third win in four games for Brisbane after a week enduring headlines for all the wrong reasons.
Broncos coach Anthony Seibold felt the heat after ignoring NSW incumbent centre James Roberts for the second straight week, opting to pick Gehamat Shibasaki to line up against NSW strike weapon Latrell Mitchell.
Shibasaki did well in his fourth NRL game to restrict Mitchell who made three errors in a quiet display.
The Roosters were on the back foot from the outset when halfback Cooper Cronk was uncharacteristically sin-binned for a professional foul in just the third minute.
Yet the Roosters drew first blood when fullback James Tedesco ran off Victor Radley to score in the eighth minute despite being a man down.
Brisbane locked up the scores at 6-6 when young prop Payne Haas crashed through three defenders to score in the 16th minute.
Both teams exchanged penalties to lock up the scores at 8-8 at halftime.
After Anthony Milford potted a second-half field goal, Segeyaro sealed the result with his try.
