About
Martin Sheppard is a former employee of KPMG who has come to prominence as a whistleblower. He reported that KPMG staff leaked confidential information belonging to their client, Optus, to colleagues who were bidding for a contract with Telstra. This breach of ethics was revealed during a parliamentary inquiry. Further allegations brought forward by Sheppard include that KPMG surveilled his laptop and dismissed his concerns as "workplace grievances." The inquiry also heard from Michael Ebeid, the newly appointed chair of KPMG, who had previously stated that leak allegations were "completely false" and described a senator's actions as "inappropriate." Sheppard's actions and the subsequent revelations have put KPMG under scrutiny for its ethical conduct and internal processes regarding confidential information and employee complaints.
