Tom Duffy made 10 appearances, mostly at five-eighth, during his 2026 rookie season, but says he wants Brisbane's halfback role in 2027.
The 23-year-old is competing with new signing Jonah Pezet and veteran Ben Hunt, who finished last season strongly at No.7 and is considered the early favourite.
Adam Reynolds retired after captaining Brisbane's 2025 premiership team and has joined the coaching staff following the Broncos' 14th-place finish last season.
Brisbane plan to use Ezra Mam at five-eighth next year, while Duffy believes halfback suits his kicking and communication.
"It's great. We're the same age and have been through the same sort of junior system and pathway, and now we've come together at the same club," Duffy said.
"We are both going for that seven spot. It's a very friendly battle, but we both want it. Dozer (Hunt) is in there as well. He wants a seven as well.
"It is going to make everyone train harder and it's going to make the team go better.
"I enjoy playing seven and controlling the team. I don't think there's much difference between a six and a seven these days, but definitely my kicking game and my communication among the team are my two strengths, which are more catered to a seven."
Reynolds has been running specialised halves drills and sharing his kicking knowledge with Duffy and Pezet.
"He will be a great link between the staff and the players," Duffy said.
Duffy also backed Mam's 2026 performances, saying he had shown strong moments alongside areas to improve.
"I disagree. I think he had a great season. He had glimpses of really good stuff and then some stuff he'd like to work on," Duffy said.
Hunt returned to training early, despite not being due back until the following week.
"He wasn't due back until next week, but he came back early yesterday fit as a fiddle, won most of the fitness and just really hit the ground running. He'll be ready to go."
