"ASIC sent emails and letters and telephoned the auditors using the current contact details provided by them. While most of the auditors responded by lodging their outstanding annual statements and paying their lodgement fees, 185 auditors are still yet to comply," according to a statement from the regulator.

"There has been ample time for auditors to come to grips with their responsibilities and multiple reminders have been issued. Auditors who do not ensure that they are aware of and meet their obligations face the risk of losing their registration," ASIC added.

"An unregistered auditor is not permitted to audit an SMSF. Conducting an audit of an SMSF when not permitted to do may have further serious consequences for the fund and the auditor."
