Adventure brief
Into the Blue: Two Days of Deep Diving with Grey Nurse Sharks off Coffs Harbour
Off the coast of Coffs Harbour, the Solitary Islands Marine Park forms a draught of deep walls, gutters and arches that host Grey Nurse sharks and dramatic drop-offs.

Set along the vibrant coast of Coffs Harbour, New South Wales, the Jetty Dive Centre delivers a standout gateway to the underwater world of the Solitary Islands Marine Park. Located at 398 Harbour Dr, this pioneering dive shop specializes in the PADI Deep Diver Course, a focused two-day experience tailored for certified divers eager to push beneath the typical recreational depths.The Solitary Islands Marine Park, a network of ecological refuges protecting coral reefs, steep underwater walls, and rich marine biodiversity, forms the exceptional classroom for this course. During four deep dives ranging from about 26 to 40 meters, divers encounter dramatic seafloor formations such as Buchannan’s Wall and encounter legendary Grey Nurse sharks, a critically endangered species known for their docile nature and unique appearance. These dives emphasize mastery of safety, dive planning, and handling the nuances of deeper water environments like nitrogen narcosis and decompression considerations.Instruction at Jetty Dive Centre prioritizes small-group engagement to ensure personalized guidance and thorough skill development. The course includes E-Learning access and culminates in a PADI Deep Diver Certification, which contributes to the Master Scuba Diver rating—a valuable credential for serious dive enthusiasts. The dive boats launch from Coffs Harbour Marina, sparing participants the hassle of shore entry, and provide access to secluded dive sites often missed by larger tour operators.Beyond technical expertise, the course situates divers in a marine hotspot known for strong currents, cool yet clear waters, and an abundance of underwater life, from giant Queensland groupers to vibrant soft corals. Jetty Dive Centre plays a vital role in the region’s dive community, combining education, conservation awareness, and first-rate logistics to offer an immersive, safe, and unforgettable deep diving adventure in one of Australia’s most dynamic coastal environments.
