The Ex-HMAS Adelaide, a former Royal Australian Navy Town-class light cruiser, was scuttled off the Central Coast of NSW near Avoca Beach to create an artificial dive reef.

Following a severe storm, its aluminium superstructure detached from the hull and settled on the seabed. BG&E was engaged to assess the structural integrity of the site to ensure diver safety, providing structural, materials, and durability engineering expertise.

Engineering review included

• Desktop assessment of dive reports.
• Materials engineering, including evaluation of exposure conditions, corrosion mechanisms, and deterioration progression.

Further works are likely at the recommendation of BG&E for multi-beam scanning and underwater ROV inspections.
