Agro For four decades, Dunn had been the voice and operator of children's puppet character Agro. Dunn rarely appeared alongside Agro, as a typical
ventriloquist might; when Agro appeared on camera or on stage, Dunn was always hidden, often by furniture. Agro was originally created in 1981 by
BTQ-7 employee Gary Rhodes. After a falling out with Seven led to Rhodes' resignation, several different operators were involved in working the puppet, with Dunn eventually hired by Seven in 1982 as a permanent replacement after they received a song demo recorded by Dunn about Agro which included an impression of the character. He began his career as Agro on Channel Seven's children shows ''Boris' Breakfast Club
and Wombat''. In 1988, Agro appeared in the television musical ''
Agro's Christmas Story, which was co-written and produced by Dunn. It was followed by A Very Agro Christmas'' in 1989. The character's popularity peaked with the morning children's show ''
Agro's Cartoon Connection'', which was noted for its sometimes provocative content, especially for a show aimed at children. The show, which won seven consecutive
Logie Awards for Most Popular Children's Program between 1991 and 1997, ran from 1990 until its cancellation in 1997. Dunn also owned certain rights to the character, such as merchandising rights, He parlayed Agro's popularity into other media, including four studio albums (of which three were nominated for
ARIA Music Awards), video games,
showbags, and even ice creams. Agro's on-camera roles became less frequent in the late 1990s and into the 2000s as Dunn's radio commitments grew and the novelty of the character had worn off; however, he still made occasional appearances on television in commercials and in guest appearances. As late as December 2025, Dunn claimed that he was in discussions with Seven to produce an
Agro Up Late special to air in 2026.
Other television In 1996, Dunn created the children's television series
Spuds In Duds, a parody of
Bananas in Pyjamas with potatoes. Dunn co-wrote, produced and co-starred in the series with longtime creative partner Ian Calder. Originally intended to be a segment for ''
Agro's Cartoon Connection'', the series was broadcast on community television channel
Briz 31. Dunn was the narrator of the
Animal Planet series
Snake Boss. ==Radio==
