About this site
Ex HMAS Adelaide is a ship wreck sunk as an artificial reef off the NSW Central Coast in Australia, and it was once one of the country's best-known artificial reef dives. The wreck lies at up to 30.5 metres and is graded advanced. The site is currently closed to diving indefinitely, following confirmed structural damage that includes the collapse of sections of the aluminium superstructure and further deterioration after major storms in July 2024.
Engineering and safety assessments are continuing, and authorities have made clear that diving is prohibited until the wreck is declared structurally safe. Unstable bulkhead joints and collapsed sections of the superstructure are the main hazards recorded.
