The ATO does have some statutory powers, but none of these give the ATO priority over other unsecured creditors of the company. In this regard, if an unfair preference payment has been made to the ATO, the Court can order the ATO to pay that back to a liquidator just like any other unsecured creditor. The only special treatment the ATO gets is that they have tools they can use to chase the directors in their personal capacity in respect of the unfair preference set aside and as well as particular unpaid tax liabilities through issuing Director Penalty Notices.
If Bonza is making unfair preference payments, that would be a matter for a liquidator to pursue should one be appointed.
