A confidential report has warned that a 2000-tonne former lighthouse tender moored at Balls Head in Sydney Harbour is at risk of catastrophic hull failure, posing an immediate and severe environmental threat. NSW Maritime seized the MV Cape Don last month after negotiations with its owner broke down, and is now exploring urgent salvage options that are likely to cost taxpayers $15 million to $20 million.
The report, by AMSA Accredited Marine Surveyors, found the vessel's hull was so badly corroded that "the risk of catastrophic failure of the port side hull plate is extremely high, which would pose an immediate and severe environmental threat." The surveyors noted that the bilge pumping arrangements were "grossly inadequate" to manage flooding, and that heavy rust at the stern left the ship "extremely vulnerable" to flooding.
NSW Maritime executive director Nicole Watts said the agency was examining several options, including dismantling the vessel in place or removing it in a "bath tub scenario" to prevent it from crumbling. Specialist equipment may need to be brought from overseas. "We've obviously got to go through our procurement process, but we're aware of the emergency," she said, recalling the 2022 sinking of the former Manly ferry MV Baragoola, which was moored nearby. "It needs to be done very urgently because things can change imminently. We don't want a repeat of the Baragoola."
The vessel, a former lighthouse supply tender, was bought by the charitable Sea Heritage Foundation in 2004. Volunteers have been restoring it with plans to open a museum, and it has been used for university research and cub scout activities. However, the confidential inspection for Transport for NSW last year raised concerns that many repairs were degraded or questionable. In addition to structural issues, the surveyors identified environmental hazards including asbestos, zinc chromate paint, and the previous use of tributyltin (TBT) antifouling paint, a chemical that changes the genders of marine snails.
Premier Chris Minns said the government had to intervene because of the serious implications for the environment and Sydney Harbour. "I'd expect anyone who owns or operates a boat in the maritime sector to follow the rules," he said. "We have to make sure that there are appropriate regulations and penalties in place if there is a breach because it can't just be shovelled over to the taxpayer when things go wrong."
The salvage operation is likely to cost between $15 million and $20 million and will be borne by taxpayers because the vessel is uninsured. Watts said many insurers were unwilling to cover ageing vessels, and Maritime NSW planned to crack down on unsafe ships. "When you go out on Sydney Harbour, you can see this is not the only vessel in disrepair. I can tell you it will not be the only one," she said.
Sea Heritage Foundation, through legal counsel George Caramanlis, disputed any suggestion it was incompetent or indifferent to safety. Caramanlis said it would be "seriously misleading to present historical observations as current findings without assessing subsequent repairs, mitigation measures and technical evidence." The foundation is exploring legal action against the Herald. It did not directly address the lack of insurance.
The removal of the ship is not expected until next year due to the logistical challenges of dismantling a vessel in such frail condition.
Analysis
Why This Matters
- The potential sinking of a 2000-tonne vessel in Sydney Harbour could cause severe environmental damage, affecting marine life and the harbour's ecosystem.
- Taxpayers are likely to bear the $15–20 million cost because the ship is uninsured, raising questions about regulation of aging vessels.
- The case highlights gaps in enforcement of vessel safety standards, with officials warning other derelict ships remain on the harbour.
Background
The MV Cape Don, a former lighthouse supply tender, has been moored at Balls Head in Waverton since 2004 when it was purchased by the Sea Heritage Foundation for restoration as a museum. Over two decades, volunteers worked on the ship, but a confidential survey commissioned by Transport for NSW in 2025 found severe deterioration. After negotiations failed, NSW Maritime seized the vessel in October 2026.
Key Perspectives
- NSW Maritime (Nicole Watts): The vessel poses an urgent environmental threat; the agency is exploring expensive salvage options and plans to crack down on unsafe vessels across the harbour.
- Premier Chris Minns: Supports government intervention but insists operators must face consequences to avoid burdening taxpayers.
- Sea Heritage Foundation (George Caramanlis): Denies incompetence or indifference, says the survey's findings are outdated and do not reflect subsequent repairs; considering legal action against the Herald.
What to Watch
- Whether NSW Maritime secures specialist equipment from Darwin or overseas for the "bath tub" salvage method.
- The outcome of the Sea Heritage Foundation's potential legal action.
- Any new incidents involving other derelict vessels on Sydney Harbour as enforcement ramps up.
