That’s what oppositions and minor parties do. Do you know how many times the Coalition tabled the NSW ICAC proposal in the 1980s?Labor and the Greens have tabled and supported a Federal ICAC proposal nine times. The LNP have voted it down nine times and never tabled their own.
It absolutely is a partisan thing.
The Greens are just wedging the major parties anyway. Easy to be anti-corruption when you’re not worth bribing.
