The current government has recognised that there is great public concern about corruption in politics, and sincerely want to do something about it. About the concern, that is, not the corruption. Hence the proposed legislation that would deal with accusations in secret. That way they can say they have a watchdog, but ensure it barks silently and nips rather than bites.
GetUp, as usual, is alert to the threat, and intends to fight it. If you want to see political corruption effectively prosecuted, think about chipping in to help.
