Transparency International's Corruption Transparency Index ranks 180 countries by the perceived levels of public sector corruption.
In 2019 Australia was one of only three countries highlighted as examples of the 21 countries countries who scores had markedly declined between 2012 and 2019 - Australia dropping 8 points from 85 out of 100 in 2012 (when it was the 7th least corrupt nation) to 77 out of 100 in 2019.
It should be noted that the Abbott-Turnbull-Morrison federal Coalition government came to power in September 2013.
Transparency International's 2019 report points the finger at Australia's poor performance with regard to rules around campaign financing, donations and grants.
Stating of counties such as Australia that; unfair and opaque political financing and undue influence in decisionmaking and lobbying by powerful corporate interest groups, result in stagnation or decline in control of corruption. [my highlighting]
It would appear that it is not just "the Twitter crazies" who are concerned about the possibly higher levels of corruption in Australian federal, state & local governments and the public service.
It comes as no surprise that the report rated New Zealand (along with Denmark) as the perceived least corrupt nation. Once again shaming its near neighbour and ally Australia by comparison.
