But politicians are among most corrupt public servants in Australia.
"The phenomenon has also been studied by the Australian National University, which produced a report called Perceptions of Corruption and Ethical Conduct (2012), which concluded: "there is a widespread perception that corruption in Australia has increased" and that "the media, trade unions and political parties were seen as Australia's most corrupt institutions."
That measure explicitly measures perception of corruption, not actual corruption.
A low rating could just mwan high corruption covered by effective propaganda directed at the masses that lack the means to meaningfully engage in corruption.
