Classic 100 Symphony

During 2009, the Australian ABC Classic FM radio station conducted a survey of listeners' favourite symphonies. Participants were permitted to vote for their three preferred symphonies. The survey closed at the end of June 2009.

The works were broadcast (from number 100 to number 1) from 12–19 September 2009.
