Under the whistleblowing regime in the Corporations Act 2001 (Cth) (CA), it is unlawful for someone to cause or threaten to cause detriment to, or victimise, a person because they believe or suspect that the person has made, may have made, or could make a whistleblowing disclosure (Whistleblower).  Very substantial civil and criminal sanctions apply for both the individual engaging in detrimental conduct and the corporation that employs the Whistleblower and the antagonist.
