Coached by Wayne Bennett and captained by Gorden Tallis, they competed in the NRL's 2003 Telstra Premiership, finishing the regular season 8th (out of 15) and making the finals for the 12th consecutive year.
In the pre-season Bruno Cullen replaced Shane Edwards as Broncos Chief Executive Officer.
A total of twelve Broncos players were selected to play in the mid-season 2003 State of Origin series, making them the most heavily represented club.
As a testament to the quality of the athletes produced at the Broncos, three of the club's former players would feature in two of the top three finishing teams of the rugby union world's peak competition, all of them having played together in the Broncos' 2000 premiership-winning side: Lote Tuquri with Wendell Sailor for Australia and Brad Thorn for New Zealand.
The Broncos were once again in the upper echelons of the ladder before losing their last eight games and falling to eighth place, nearly missing the finals for the first time since 1991.
