This dive site centers around the iconic Catherine Hill Coal Loader, a prominent feature of the bay. Descending to a maximum of 10 meters, divers can explore a fascinating underwater landscape dominated by the remains of the old loader, including a myriad of ship chains, cables, and other hardware. The site also holds the scattered remains of the SS Wallarah, offering a glimpse into its maritime history and providing intriguing structures for navigation and exploration.
The sandy bottom and structures attract a diverse range of marine life. Divers can expect to encounter vibrant schools of fish, numerous nudibranchs, and various sea stars. Rays are frequently found gliding across the sandy patches. While sightings are not guaranteed for divers, bull sharks have been reported by surfers in the area, adding a touch of potential thrill.
Being a shallow and relatively sheltered site, Catherine Hill Coal Loader is suitable for divers of all experience levels, including beginners. Its shallow depths make it particularly appealing for freedivers and snorkelers seeking interesting underwater features and marine encounters close to the surface. The site offers excellent opportunities for macro photography due to the abundance of small creatures. No specific best time to visit is mentioned, but generally, calm weather conditions will ensure the best visibility and enjoyable experience.
