Controversial broadcaster Alan Jones has been ordered to undergo basic journalism training by Australia's media watchdog.

The Australian Communications and Media Authority (ACMA) says Jones will have to undertake training on "factual accuracy and significant viewpoints" as part of measures agreed with his station 2GB.

The shock jock has been deserted by sponsors and advertisers after telling a dinner organised by the Sydney University Liberal Club that Prime Minister Julia Gillard's father had "died of shame" because of his daughter's "lies".

But ACMA acted after finding that Jones breached commercial radio codes of practice in a statement he made about carbon dioxide emissions in March last year.

The ruling states that Jones said on air:

"Remembering all this when the percentage of man-made carbon dioxide Australia produces is 1 per cent of .001 per cent of carbon dioxide in the air. Nature produces nearly all of the carbon dioxide in the air. Human beings produce 0.001 per cent of the carbon dioxide in the air and Australians produce 1 per cent of that. That's 1 per cent of .001 is .00001 per cent of the air. 1/100000th."

ACMA ruled that an ordinary reasonable listener would have understood the material as a statement of fact, not opinion.

It said 2GB has not provided evidence that it or Mr Jones had taken any steps to ensure the statement was accurate.

It said it had agreed a list of new measures with 2GB which Jones would have to stick to in the future.

A statement on the ACMA website said the measures included:

Pre-broadcast fact-checking by the program's executive producer of any material provided by non-media sources or third parties which may require additional confirmation and attribution.

Pre-broadcast fact-checking by the program's executive producer of any material provided by non-media sources or third parties which may require additional confirmation and attribution. Creation and retention (for at least six weeks) of records of the verification material sourced by the executive producer for the facts contained in the editorial piece.

Creation and retention (for at least six weeks) of records of the verification material sourced by the executive producer for the facts contained in the editorial piece. Identification by the executive producer of controversial issues of public importance that are not covered by other 2GB current affairs programs.

Identification by the executive producer of controversial issues of public importance that are not covered by other 2GB current affairs programs. Communication of these exceptions to 2GB's program director who will then be responsible to ensure that another current affairs program presents an alternative, significant viewpoint to that presented in the program hosted by Alan Jones so that 2GB can discharge its obligations under the Commercial Radio Codes of Practice.

Creation and retention of records by the program director for the above steps.

ACMA also said that: "Training will be conducted [including with Alan Jones] focussing on the ACMA's findings concerning factual accuracy and significant viewpoints."

It ordered him to complete the training by the end of November 2012.

Jones is yet to comment on the ACMA ruling.

Editor's note (23/10/12): The story originally stated Jones's comments were made at a Young Liberals conference. They were in fact made at a dinner organised by the Sydney University Liberal Club.
