In April 2011, New South Wales took an unusual approach to an old naval frigate. Instead of sending the ex-HMAS Adelaide to a wrecking yard, authorities deliberately sank the former Royal Australian Navy warship about 1.8 kilometers off Avoca Beach on the Central Coast of New South Wales, creating an artificial reef for marine life and recreational divers. The ship was placed at a depth of approximately 32 meters, and its changing underwater community was monitored over the following years. The ecological monitoring recorded 62 fish species from 31 families across the five-year monitoring period, along with a range of marine organisms that gradually colonized the wreck. The site remained a dive attraction until July 2024, when Crown Lands closed it because structural damage associated with storm events and coastal processes had created safety concerns.
