ASIC probes big four firms after KPMG scandal

The Australian Securities and Investments Commission has commenced an investigation into how the big four accounting firms manage internal complaints.
The corporate watchdog faces structural limitations under current laws because its jurisdiction applies primarily to individual registered auditors rather than partnerships.
The enquiry comes as the federal government considers stalled legislative reforms aimed at expanding regulatory oversight and increasing sanctions for accounting partnerships.

The Australian Securities and Investments Commission has launched an investigation into the handling of internal complaints at KPMG, Deloitte, EY, and PwC using compulsory information-gathering powers.

The intervention follows revelations that KPMG initially failed to adequately investigate a whistleblower's claims regarding misconduct within its audit division.

"The allegations concerning KPMG are serious," said ASIC Chair Sarah Court.

The investigation focuses on the alleged improper access of client data from major companies, including Lendlease, Dexus, and Optus, by three registered auditors.

The controversy has led to the departures of several senior executives, including CEO Andrew Yates and chairman Martin Sheppard, after the details were made public in federal parliament.

Five external bodies are now investigating the matter alongside four separate reviews funded directly by the firm.
