The Protected Disclosure Act 2012 (the Act) established the Independent Broad-based Anti-corruption Commission (IBAC) and facilitates the making of disclosures about serious improper conduct by public bodies or public officers. The Act provides for a system for such matters to be confidentially disclosed and impartially investigated. The Act also provides protection from detrimental action to the discloser. Disclosures must be made directly to IBAC. Contact details can be viewed here.
