ACFS Port Logistics, the container logistics operator controlled by the billionaire Tzaneros family, is facing a potential wind-up application from the Australian Taxation Office (ATO) over unpaid debts totaling approximately $60 million.

The company has moved to head off the threat as early as this week, according to reports from the Australian Financial Review.

The tax dispute adds a new layer of financial distress to the firm, which is already embroiled in a separate legal battle.

Transurban, a major infrastructure owner, has previously filed a petition in the Supreme Court of New South Wales to wind up ACFS Port Logistics, citing a pattern of late payments and contractual disputes.

The convergence of creditor pressure from both the state tax authority and private sector partners signals deepening liquidity challenges for the logistics group.

For market participants, the escalation raises questions about the operational stability of key port logistics nodes in Australia.
