Jamie Dunn was the undisputed king of Brisbane radio, when the B105 Morning Crew was at the heart of the station's incredible ratings success during the 1990s and early 2000s. Jamie was also the voice and personality of children's character Agro.

With features like 'Agro to the Rescue', 'Gotcha' calls and the Royal Children’s Hospital appeal, Jamie (alongside Ian Skippen and Donna Lynch, who was later replaced by Robin Bailey) created a Brisbane show that became the benchmark for FM breakfast radio.

Jamie then joined The Morning Crew in Sydney alongside Wendy Harmer and Paul Holmes. Dunn has also hosted a variety of children's television shows, although he has retired his alter-ego Agro.
