Victoria's corruption watchdog will be given powers to retrospectively go after organised crime figures and bikies connected to government project criminality.
The state Labor government on Monday responded to a report by parliament's Integrity and Oversight Committee, which recommended a major overhaul of the Independent Broad-based Anti-corruption Commission (IBAC).
It supported 21 of the committee's 29 recommendations for government in principle, including giving the independent integrity agency "follow the money" investigative powers.
The watchdog can investigate public officials or bodies, but not contractors or third parties such as union officials and bikies, under its legislative framework.
It has been calling for "follow the money", also known as "follow the dollar", powers since 2017.
"Let me be clear, I want the follow the money investigative powers to be retrospective," Premier Jacinta Allan said.
