The corporate watchdog has yet to be contacted by the liquidator in charge of the collapse of Home Australia and its subsidiaries, owned by retiring Family First senator Bob Day.
Senator Day announced his resignation from parliament on Monday to deal with his fallen home building empire.
Australian Securities and Investments Commission deputy commission Peter Kell told a Senate estimates hearing as this collapse is a "new event", the liquidator is still reviewing the company.
"The liquidator is bound to report to us if the liquidator believes or suspects there may have been misconduct under the corporations act," he told the hearing.
Asked if there has been any complaints about Home Australia in the past, Mr Kell said said there may have been a small handful, but he took the question on notice.
