The third independent editorial audit of ABC content has found that the public broadcaster's local radio stations are in touch with the concerns of the community.

When announcing the audits last year, ABC chairman James Spigelman said he was concerned ABC journalists reflected the issues of interest to an educated elite rather than the general public.

Complaints about ABC bias are usually driven by the topics chosen rather than the content, he said.

"Journalists - all of you, not just those at the ABC - tend to have a social and educational background, perhaps particularly in Canberra, Sydney and Melbourne, that may make them more interested in, say, gay marriage than, say, electricity prices," he said. "As a public broadcaster, we must endeavour to engage with those sections of our community who are concerned with the latter."
