The biggest part of corruption in this country would have to be in the banking sector.
I've seen it all over the last 3 years, people being setup to take all their assets/money, a pensioner who can't read or write signed up for a $1m loan (which he never got any money for), banks refusing to let people pay out loans,
The ANZ rate rigging scandal, Bankwest risk regrading, CBA predatory lending and now the latest on 4 corners with commonwealth insurance. I'm now keeping all my assets and money as far away from banks as I can.
Hopefully a royal commission will follow soon and the members of the 'big 4' organised crime gangs brought to justice.
