chair James Spigelman announced that four independent audits would be conducted each year in response to the allegations of bias in the reporting of news and current affairs. ABC Friends have observed that "Most of the complaints about bias in the ABC have come from the government of the day – Labor or Liberal. Significantly both parties have been far less hostile to the ABC when in opposition". Reviews and investigations Reviews of the ABC are regularly commissioned and sometimes not released. Both internal and external research has been conducted on the question of bias at the ABC. These include the following: A 2004 Roy Morgan media credibility survey found that journalists regarded ABC Radio as the most accurate news source in the country and the ABC as the second "most politically biased media organisation in Australia". A 2013 University of the Sunshine Coast study of the voting intentions of journalists found that 73.6% of ABC journalists supported Labor or The Greens – with 41% supporting the Greens (whereas only around 10% of people in the general population voted Green). At the 2016 federal election, a study commissioned by the ABC and conducted by Isentia compiled share-of-voice data and found that the ABC devoted 42.6% of election coverage to the Coalition government (this compares to the 42.04% vote received by the Coalition in the House of Representatives (HOR)), 35.9% to the Labor opposition (34.73% HOR), 8% to The Greens(10.23% HOR), 3.1% to independents (1.85% HOR), 2.2% to the Nick Xenophon Team (1.85% HOR) and 8.1% to the rest. However, the ABC itself notes the "significant limitations around the value of share of voice data" as "duration says nothing about tone or context". In December 2020, the Board commissioned its 19th editorial review by an independent reviewer, which found that the ABC's news coverage of lead-up to the 2019 Australian election was "overwhelmingly positive and unbiased", although it also found that specific episodes of The Drum and Insiders reflected too narrow a range of viewpoints. The government forced the publication of the report after Coalition senator James McGrath raised a motion in the Senate, which led to ABC Chair Ita Buttrose and managing director David Anderson writing to the president of the Senate, Scott Ryan, to express their concerns about the use of the such powers, which went against the public interest.
