What you hear on community radio is governed by the Community Radio Codes of Practice.

The Codes of Practice cover matters relating to program content, including local content, news, current affairs, Australian music content, programs for children and the responsibilities associated with broadcasting to the community.

They also cover aspects such as community access and participation in the operation of this service.

Copies of the Codes are available on the Community Broadcasting Association website.
