Brisbane have secured another key figure in their coaching ranks, with Queensland Origin assistant Matt Ballin opting to extend his stay at Red Hill.

The former Manly hooker had been a target for both the Titans and Cowboys, but has chosen to turn down rival advances and sign a fresh deal with the Broncos.

The move is the latest in Brisbane's multimillion-dollar retention push, ensuring stability around head coach Kevin Walters as the club prepares for another crack at premiership glory.

Ballin has quickly earned a reputation as one of the brightest young coaches in rugby league. Already part of Michael Maguire's Queensland State of Origin set-up, he has played a significant role in guiding Brisbane back into contention, with the club now preparing for a preliminary final next weekend.

The NRL assistant coaching market has been particularly active in recent weeks following the sackings of Des Hasler and Adam O'Brien, which set off a wave of staff movement across the competition. In that environment, Ballin's commitment represents a major win for the Broncos.

Seen as a future head coach in the making, his decision to remain at Red Hill not only shores up Brisbane's coaching depth but also sends a message of loyalty at a time when rival clubs are circling.
