Originally, when it started in 2001, the station played classic rock hits, with a little bit of current pop tracks, using the positioner "The Biggest Variety of Rock & Pop". In 2004, its music format shifted more towards CHR, and with it came a change of its positioner to "The Best Music in Macarthur". In early 2006, when Rob Doorey replaced Mal Lees (formerly of Triple M's Club Veg) & Mardi Cole, both now at other stations, for its breakfast slot, their positioner was changed to "Macarthur First".
