The Bulldogs lost star second-rower Viliame Kikau to a pectoral injury in an opening half at Suncorp Stadium on Friday that was close to perfect by the under-strength Broncos.
The Broncos were without Test stars Payne Haas, Pat Carrigan and Reece Walsh, as they were last year when they conjured a comeback 22-18 win over the Bulldogs in Sydney.
Their replacements were immense. Ben Talty and Jack Gosiewski powered on as starting props, while fullback Hayze Perham, making his first start in the NRL in 964 days, had a hand in two first-half tries in a stellar display against his former club.
The defending premiers gave an NRL debut to prop Va'a Semu and a club debut to versatile forward Preston Riki, who was put on report and sin-binned for a high shot on winger Jonathan Sua in the second half.
The finishing of the hosts was out of this world. Magic Round is three weeks away, but five-eighth Ezra Mam and winger Deine Mariner were conjurers to ground the ball in the corner for tries without going into touch.
Mam had one of his best games in the NRL and in cahoots with skipper Adam Reynolds totally controlled the match.
"I was really proud of the players," Broncos coach Michael Maguire said
"People talk about what is not in the team. I am more about having a good time with the players that are in the team.
"The captain is looking after the younger ones coming in and there is a calmness about how he is going about things. We have just got to keep bottling it."
The Bulldogs were toothless in attack and the early return of skipper Stephen Crichton had little impact.
"We couldn't take our opportunities up their end of the field … and we gave up too easy down the other end," Bulldogs coach Cameron Ciraldo said.
Brisbane's defence on their try-line was immense. Centre Kotoni Staggs, on one leg, was brutal with his work. When outside backs Gehamat Shibasaki and Josiah Karapani threw Crichton over the sideline early, it was a statement moment.
A Mam grubber set up centre Shibasaki for the opening try.
Reynolds managed the game to perfection and Mam added the classy flourishes like the scintillating cut-out pass he hurled for winger Karapani to make it 10-0.
Bulldogs bench forward Harry Hayes stuck his leg out to trip Reynolds and was sin-binned, with the Broncos then making their opponents pay.
When Mariner scythed past three Bulldogs and finished with a freakish put-down in the corner, the gulf between the sides was never more evident.
Perham threw the final pass for the Mariner try and his line-break assist was the catalyst for Cory Paix to race away and make it 20-0 at halftime.
Kikau went down in the 10th minute and battled on, but disappeared up the tunnel 11 minutes later.
"He's a tough guy Vili, so the fact he had to go off isn't a great sign," Ciraldo said.
Mam was horizontal in the air and facing the wrong way when he somehow grounded the ball for the first try after the break.
Matt Burton and Lachlan Galvin got the Bulldogs on the board, but it was too little, too late.
Broncos second-rower Brendan Piakura was replaced after aggravating a knee injury in the second half.
