Up until 2005, Dunn was a member of a radio breakfast show in Brisbane. Dunn was an original member of the B105 Morning Crew, along with Donna Lynch and Ian Skippen when the station was first launched on the FM band in 1990. Whereas originally Dunn performed on B105 as Agro, over time he came to be credited as himself. The B105 Morning Crew led the breakfast time slot ratings until the end of 2004 (for about 115 consecutive radio surveys).
