The 2009 Brisbane Broncos season was the 22nd in the club's history and their first without foundation coach Wayne Bennett. They competed in the NRL's 2009 Telstra Premiership and by the 12th round were leading the competition, but then suffered one of their worst post-State of Origin form slumps ever and spent rounds 16 to 22 outside the top eight. The team managed to finish the regular season 6th (out of 16), qualifying for the finals for the 18th consecutive year. The Broncos then came within one match of the grand final but were knocked out for the 3rd season in a row by eventual premiers the Melbourne Storm (who months later were found to have been cheating the salary cap over the previous four seasons and had all honours achieved during the period nullified by the NRL).
The new post-Bennett Broncos era got off to a thrilling start when they defeated the North Queensland Cowboys 19-18 in round 1 at Suncorp Stadium in the first game under coach Ivan Henjak. Star signing Israel Folau scored his first try in Broncos colours and the first try of the season for the club in the 6th minute, followed by NRL debutantes Antonio Winterstein and Jharal Yow Yeh who also crossed. In round 2 the Broncos defeated the Melbourne Storm for the first time since the 2006 NRL Grand Final. Israel Folau was up against his old club for the first time and scored a try in the 11th minute and second for the year for the Broncos.
For the second year in a row, The Broncos won the opening three rounds of the season when they defeated the New Zealand Warriors 26-10 at Mt Smart Stadium. In the following days Shane Webcke, who had been appointed assistant coach for Brisbane at the start of the season quit his post in the wake of controversy surrounding the release of his new book in which he was critical of some Broncos personnel. Later that week Wayne Bennett returned to Brisbane with the St. George Illawarra Dragons for round 4, coaching against his old club for the first time. Brisbane conceded their first loss of the season in what was also Darius Boyd's first match against his old club and the Dragons' 8th straight win against the Broncos.
