ACNielsen is the official contractor for radio audience surveys in all markets throughout Australia, providing detailed listening data for radio stations in Sydney, Melbourne, Brisbane, Adelaide and Perth, eight times per year. Regular surveys are also conducted in numerous regional markets.

The Federation of Australian Radio Broadcasters, FARB (www.radiomarketing.com.au), currently administers the radio ratings contract contract on behalf of all commercial radio stations, and assists in the continued improvement of the research program and the audit of the survey methodology. Considered to be the most advanced of its kind anywhere in the world, ACNielsen's diary system is based on personally-placed and collected diaries, which record seven day, quarter hour listening by pre-listed stations.
